🔥 Silver Soldering Basics and Technique

[@thefreedomwarrior]

Bob has to be the real deal. Looks like he raised a good kid.

[@MrShobar]

I'd would never have talked to my father like that.

[@haroldwatkins7059]

I truly appreciate all your videos. I saw how proud you were of your son. He will be fine. I am 62 years and a 100% disabled Vet from A.F. I had a great time and started learning how to solder and weld while I was in. Refrigeration Shop. He will do well sir. Again, Thank you for all your instructions.

[@retireddec04]

1st and only time I used silver solder was in tool and die school. Soldered high speed steel tips onto cold rolled steel for boring bars. They are still holding up 10 years later. Good stuff.

[@freddyrasheed528]

I am so very impressed, with ALL YOU DO, when I started in this industry in vocational school in high school, these are the things we learned how to do and it doesn’t seem like they show or teach the stuff a lot anymore, I love the old-school ways and the way you conduct yourself. So I just want to say thank you for what you give back to the industry.

[@waynenocton]

In a pinch I once silver soldiered a clothes dryer element and then ordered the replacement to make the full repair later on. It ended up outlasting the dryer itself, I never did put the new part on. Great video.

[@thelement3363]

That scuffle between you and your son was awesome example of give and take. Thanks gents.

[@CTmoog]

Used it all the time on copper pipe back when I used to install a/c systems. Cool video!

[@jolkraeremeark6949]

Would this technique work on a chainsaw exhaust?

[@w5cdt]

Great for refrigeration copper tubing.

[@Gears.and.Gadgets]

I have been using brazing techniques for years. In the Refrigeration industry I either braze with sil flos or silver solder.
Best rule of thumb is copper to copper is sil flos.
Copper to anything else is silver solder.

[@bobmoffatt4133]

Thanks for the feedback. Good intel.

[@Harry-ei7os]

How's about stainless to steel?

[@jsfkdkjslfdslfkdj]

Stainless to carbon steel can be done with a 56% silver brazing rod with a paste flux

[@Lahainalongboarder]

There’s so many different kinds of flux. Can you use just regular flux found at a plumbing supply store?

[@phiksit]

Just make sure it isn't soldering flux. You want the white paste flux in the plastic jar. There's a ton of different brazing alloys too. Only a few seem to be available to us every day folks.

[@ls2005019227]

Bob, thanks for another great video. Tell your son thanks for his decision to serve our country.

[@withoutdad7616]

awesome video Bob. Simple and to the point. Good to see the young ones being productive even if they are lippy and disturbing the tools.

[@Bluelightbandit]

lol love Tombstone! Seen that movie about 50 times! Thanks to your son for serving our country. respect!

[@JG-mp5nb]

Haha! We have the same yard tool and it broke exactly where yours did. My husband drilled and tapped it and it’s still going three years later! All of a sudden they’re ready to go , and they don’t visit and call as much! Good luck to him-go active!

[@talshaharfamily]

God bless you on supporting our military! From one vet to another, thank you!

[@Notmyhome-y7y]

I have worked with silver solder and flux for many years. Orthodontic appliances are made with silver solder, stainless steel, solder, a superfine torch flame and human hands. The appliances are extremely durable.

[@ghffrsfygdhfjkjiysdz]

Great video. Here are couple additional details for the viewers: Soldering and brazing are essentially the same technique. The difference is the temperature. Above 830 degrees F it's brazing, below is soldering. The MAIN difference is that in brazing the surfaces are hot enough to burn off the oxides off, hence much less surface prep is required. In soldering the surface prep is very important, because metal does not get hot enough to burn off oxides and other gunk.Usually silver solder has up to 8% silver content, while brazing rod goes to 20%. In AC industry brazing is required for R410A systems, because they run at higher pressures.

[@ScottTheis]

Thumbs up for your son's service. Thank him for me and mine.

[@myrametals]

Really great video regarding silver solder! Great young man assisting as well! As a sales person for the welding industry, your videos really help EVERYONE- I'm a huge fan and will continue to be!

[@ddcd53]

Nice video, very informative. I'm enjoying these videos on the brazing and oxy/acetylene welding very much. I think every welder should learn the o/a and the brazing before the stick, mig and tig. O/A is real welding. Once you learn that, the rest is easier. Just my opinion. Thanks Bob for these vids. Dan.

[@chrisbeard5794]

Oxyacetylene was what attracted me to welding in 5th grade im 33 now and I have done all the welding processes SMAW, GMAW, GTAW, FCAW but out of all of the faster processes I still prefer Oxyacetylene became sort of a expert in it controlling the weld pool and the torch.

[@codyguynn6386]

long time viewer, first time comment. thank you sir for all the time and energy put into your videos. I am not certified but not many of us in the fencing and gate industry are. therefore I appreciate the diversified non opinionated education I find on your channel and have used things here and there to become a better welder. I charge more for my welds than I used to
and I believe I owe a thanks to you and a few other you tubers. thank you sir -Cody starline fence and gate panama city beach, fl

[@thebmac]

these videos really help to see the everyday applications that can be done. Thanks for all your videos.

[@rondumontier1187]

I got my 1st job cuz I could gas weld, braze, solder. One person said we should learn this 1st, he,s correct. Nice video

[@anthonydwilliamson]

Thumbs up for the "go heels" Tombstone quote. It's like your working with your brother's kids or something

[@daveybernard1056]

nice

[@johnchadwicktilton]

Can you name off the Silver Solder rod types and the Flux , possibly leave links ?

[@JayKayKay7]

About to fix my mother's broken silver service set; two handles need to be attached to a bowl. You popped up as the first You Tube on 'silver solder'. I learned a lot and you demonstrated the basic process. Thanks. Of course, I'm going to roll with the Craftsmen MAPP yellow home gas and Ace hardware alphaFry #53982 Specialty Soldering Kit featuring silver solder solid wire and flux. Seeing as how I am clueless and have a tremor, I think all will be well and the repair will be successful.
You have a fine son and I hope the Army bit works out. (ex Air Force, myself.)

[@dougmaz1]

Bob I do lots of silver soldiering for my model engineering steam engine’s and I only use a very soft flame held about 2” away from the job and wave it back and forth then all of a sudden the flux starts to go watery and shiny then touch the silver soldier on the job and then it flashes around the part it even flows up hill. I started when I was your son’s age now I’m 82 yo. I would use that flame you used to do brazing on thicker materials not silver soldier because it only burns the flux and it will go black in between the two metals stopping it flowing. Doug in Australia.

[@jeffhall2958]

Bob, nice demo for newbies. As I'm in an HVAC&R trade person, I would have to say your techniques are lacking concerning silver soldering/brazing. If I have the chance after this "Covid-19" scare goes away, perhaps a person such as myself can show you a different way of silver soldering, and properly. That metal should have never been "red-hot". Feathering a torch is an art, and takes practice. You heated that stainless entirely too hot. Just my 2ç.

[@bhein67]

This was a great video Bob. I was searching for info on silver soldering carbide tips for turning tools and am glad you had a video. I really like your logical straight forward way of approaching projects. I have watched many of your videos and have learned from them all. Cheers

[@ronalddavis]

look up stephen gottswenter channel. hes a machinist in germany and has a video on what you describe. i might thavespelled his name wrong but its close enough to find it

[@dalebennett5227]

More silver and brazing videos, Please.

[@seamanjive]

Just what I needed...got to fix up a tiny leak on the vaporiser tube of a kerosene lamp. I'm thinking bit of flux, silver solder rod and run it in. My Dad was a welder, wish he was still here !

[@stewartalbert3523]

In my work life i silver soldered copper alloys used in resistance welding applications . A tough one is a scintered material of tungsten and copper , hard to "wet" and too much heat causes tungsten to precipitate to bottom of weldment . Another tough one was induction heating coils made from rectangular copper tubing .

[@101bennyc]

ALL BUCKLE NO KNUCKLE

[@Mentorcase]

I broke the inner cable of my dremel extension and just silver soldered it for a temporary fix while I waited for a new cable to come in the mail, that was more than a year ago and it is still going strong.

[@dasvelo3758]

Great stuff! More silver brazing please, perhaps show its limitations too. Awesome belt buckle!!

[@georgecurtis6463]

Silver solder is sadly under rated. I used it for certain repairs on automobiles. Strong and clean.

[@kenstahl5504]

Man I love this channel

[@thanasisathanasi4965]

You and your son are wonderful. Thank you for the wonderful video.

[@leonardpearlman4017]

Silver solder is great! There's all kinds of it. I've had trouble doing this on stainless, got it overheated or something, maybe didn't clean enough first. I'd love to see some close-ups of this while it's happening. Have had good results with blue or other (Tin Man Tech) lenses that take out the sodium flare so you can see better. Yeah, the number one thing about this stuff I think is working dissimilar metals, that comes up all the time!

[@patw52pb1]

Using the correct flux and cleaning are important for a good joint.
I have had good results on stainless using Harris Stay-Silv Black, it seems to remove the contaminates and oxides better than other fluxes and tolerates the higher temps required for getting a good bond on stainless.
A coworker swears by MuggyWeld and to be fair his final product looks good and seems to hold together, but I do not have any firsthand experience.

[@leonardpearlman4017]

Hey, I tried the Black flux, it worked the first time! Looks funny in use, but when I washed it off the stainless looked like new. This is with Stay-Silv 45 and regular 304 stainless, and a big honking Harris air propane torch. Will try tomorrow with Oxygen. Thanks!

[@patw52pb1]

Cool.
You are welcome.

[@banjosambar]

Love the tombstone quote 😎👍🏻

[@richardplatt2020]

Great video

[@thor-dx8sz]

One of the things I thought was really neat is how high of a tensile strength some sodders can have when i thank of solder i immediately think of circuit board solder

[@chrismadaj8751]

My Dad used silver solder all the time and said it was a super strong weld he was a machinist like you said it flows really thin

[@Mudsuitable]

I've used silver solder to replace front sight on old guns and joining hss shafts to carbide cutting inserts for odd mill/lathe jobs, if also used it for a few other jobs I'd never admit doing while nobody was lookin... The old "looks good from my house" kind of halfassery

[@MrKidkiller159]

nice little repair. thanks for sharing you many years of expertise.

[@aubreymatthews1021]

I’ve never found a solder with the capillary action that silver solder has, great video and a good dad.

[@Golgafrinchamdent]

Ha... didn't expect the Tombstone runthrough. My favorite western :)

[@user-cm9uh6sj7n]

is very useful to know about such techniques it can get things back on line know all the processes including gas welding and soldering techniques

[@joek2858]

Thank you very much! Awesome skills.

[@mjsoup29]

Nice video and presentation- thank you!

[@cdrom1070]

having a bit of braze around can save you money and time. Its easy to do and you can get a more then acceptable repair on many objects. The best one I did is repairing a really old lock (100 years old) for a door to some closet or something. Exact fit when I was done, its strong, and they did not need to remake a door or hire a carpenter. Easily saved someone like $1000 (some home owners don't accept a solution that does not match the decour for custom stuff).

[@kevinhornbuckle]

This is very helpful. Thanks. Your handsome son obviously has a future. Congrats.

[@triggeral]

LOVE THIS! THANKYOU FOR EXPLAINING AND SHARING!!

[@lloydsims1573]

I saw the scoop get red hot. I've silver soldered a few things with propane, but unless I'm welding, the only time the parts get red is when I'm brazing.

[@andygeorgiou2846]

First video I watched and it was amazingly clear and educational. Thank you Sir.

[@dandexinventor]

Thanks for the guidance and great to see you and your son having fun. My son and I joke around a lot too.

[@billy19461]

Love the video, hug 🤗 your son and tell him you love ❤️ him while you have the chance. Lost one of mine in a car accident, someone went to sleep and crossed the center line. I am a retired welder and I was wondering if a neutral flame would have made a difference?

[@phiksit]

Soft neutral flame with a small rosebud is best... imo. His fit up on that one tab was too big also. You need a tight fit up for capillary flow to happen.

[@semperidem2577]

Nice to see you add in the homage to Tombstone in your banter.

[@Darthbelal]

Sweet video. Oh, and I caught the "Tombstone" reference....

[@GosselinFarmsEdGosselin]

Not sure how I missed this one... A year ago!!! Hmm. You tube has been a bit sketchy with notifications..
Another great video Bob!!
Thank you!!

[@briantheprion]

2:25 is that a tombstone reference? Ha love it!

[@tonytully931]

there is a place in my area called TM technologies. he specializes in torch work. lots of brazing, welding, and soldering materials

[@boohootoo1000]

congrats to your son and yourself and best of luck in military service. go army.

[@skiptracer8703]

You make it look so simple

[@fireofenergy]

You mean I don't get to see the test? Darn (and that was a mighty fine video).

[@ScrewDriverxxx]

Thanks. Close up of the finished article would be nice...

[@boramir7]

Really appreciated your instruction. Can you explain when to use regular solder and when to use silver solder?

[@zeroumashi2947]

what's shown in the video is considered brazing because the base metal was above 840°F.
the difference between soldering and brazing is filler melting temperature, base metal temperature, and tensile strength.
both soldering and brazing use capillary action but brazing filler can also be built up to fill gaps if needed.
brazing works great for steel and similar metals, but not so much for copper.
I prefer soldering with *silver bearing* solder over brazing when dealing with copper, the copper surrounding the braze joint will anneal and lose most of it's strength.
I suggest soldering over brazing unless you're going to need lots and lots of tensile strength or are placing metals in very hot places like an oven.

[@mulebarn1949]

Fitting ends to motorcycle cables silver solder is the only thing too use.

[@dorsetengineering]

my first day at my first job in a sheet metal shop - 'can you silver solder?' the foreman says. yep, I sure can... on that job for the next 5 weeks, silver soldering m10 studs into 6mm mild steel plate. I did over 900 of those plates, each with 8 studs in.

[@broken1965]

Mention SS comes in preformed rings also map gas works great also to control heat. Use at work in production environment

[@patrickbehan8737]

Good video Bob would like to see you use silver soldersed again in different applications

[@pierdolio]

Good preparation is very important.

[@spudpud-T67]

I would have fit the handle to the scoop better before brazing, or soldering. The closer the fit the better. The silver will work by capillary action. In my jewelry an invisible fit gives the best strength and a minute use of solder. It is so fun to silver solder, so user friendly.

[@jdog4534]

What's the difference between this silver solder and silphos 15? Ive gone through pounds of of solphos 15. Sometimes ill go through a couple pounds of it in a day. It's what we use to join our medical grade copper pipe in hospitals and labs. We have to fill the cup 100% then I like to cap it off. Those 4"Ø and 6"Ø lines will just drink that stuff til they're full. Of course we keep a nitrogen purge going inside the pipe the whole time to displace the air so copper stays nice n shiny..

[@samiayyat4826]

love the relationship. will watch for more vids.

[@johnscahill3273]

well described thankyou

[@LifeSavingDefense]

Thank you.

[@aguy7039]

That's a real shop. Tile Walls. You know what you are doing.

[@MrNigel1340]

Thank you, an interesting and well laid out video, regards Doc Cox.

[@Quadflash]

Bob, looks like you've raised a fine young man.

[@jwills8606]

Couple of things: First - I got the reference to Tombstone immediately. (I think it's actually, "get the bulge on a DUB like you," not TUB.Second - was this real silver solder - you know, with the majority component real silver? The reason I ask is that I've done a bit of "silver soldering" with the stuff you get at the welding supply shop, and it works ok. On a whim, I ordered some real silver solder and was amazed to find that it would easily solder chrome plated items and stainless. Maybe the other will, too, but I was blown away to see it wet the chrome.

[@robertsmith4861]

70,000 lbs tensile strength would be correct. Watching the heat; a muted sunrise is almost too hot, in my experience. For small parts you'll want to invest in a porcelain brick or two for heat concentration; you want to heat the part, not the table or vice as well. Read the heat like you'd read the puddle; You want the flux to be at it's optimum viscosity just before it passes that latent heat threshold and boils out. I used a #000, with a nice long neutral flame and using the tip of that blue point. I've never used that low of pressure settings but will have to try it. Also have done a fair amount of aluminum brazing. Fun stuff.

[@boblitchko2979]

Another great video.Didn't know silver solder is 70,00psi.

Thanks! I need to repair the headlight rings on my 1930 Packard

[@scottyglenwalker2345]

How would you recommend soldering a leg back onto a silver tea pot? I can see they tried repairing it with putty but since I told my partners mother in law I weld for a living she gave this to me to figure out lol lowes doesn't have much if a selection I got the spray on liquid flux and just regular electrical soldering wire

[@rayrenzi4860]

Great vid and informative,Thanks

[@oblazeo]

I fixed that exact tool with my Mig welder and even on the lowest power setting it did burn through the inside. I had to sand it. It was probably my fault. :)

[@GeneralMe100]

I had no idea Kevin Costner was a welder in his spare time.

[@jamesdavies7526]

Good video! I am always puzzled by the dislikes! What is there to dislike about what I consider honest effort on your part?

[@burrowssj]

thank you for these videos, keep up the good work!

[@NitroAl]

Wish I could get a couple years out of one packet of silver solder, 500g about every three months doing diamond saw blades and core bits. It's not bloody cheap.

[@enganear]

Will silver solder be strong enough at temperature for automotive exhaust fittings, not at the manifold?

[@themotofixery]

silver solder some carbide tool bits?

[@BisdremisKostas]

i wish i could like this comment 10 times

[@themotofixery]

why don't i just have someone do my machining for me? then i can try to convince my wife to wipe my butt as well...

[@KowboyUSA]

The Moto fixery on some of the huge saws and planers at lumber mills the carbide teeth and blades silver solder/brazed in place. It's amazing how strong it can be when done right.

[@gregvisioninfosoft]

for one desiring to try this, can you suggest a currently available flux and silver solder product? Thanks. My goal is to solder 1/16" thin steel, or stainless steel sheet. does the process work easier with mild steel or 304 or 316 ss material?

[@johndemore6402]

I've got a question please
I'm replacing an evap system
Air Suction pipe with copper
PIPE and elbow I'm 99% sure
I'd be okay with lead free silver solder but would leaded solder work as I believe gasoline eats lead so yeah any advice

[@johnhall8455]

Should’ve made sure there was a better flush fit before starting, and more flux required on the second attempt

[@zep909]

Thanks, great information!

[@jackvolkwyn470]

IVE GOT A REAL SMALL TIP IN HERE

[@WesAxson1]

thank you for the information

[@fortheearstohear7824]

Can you use Mapp gas to Silver Solder ?
I have a small cast ring 2" dia. (China) dresser handle, would SS work that or maybe brazing it would be better?
