MIG Welding Techniques

Watch this video for an introduction to MIG welding. MIG welding (GMAW - Gas Metal Arc Welding) is the most common process used in home shops, small businesses, manufacturing and metal fabrication applications. Here you will learn about equipment setup, basic housekeeping nad techiques for various welding positions.

Nice looking weld at the end there

[@tar21gi]

@Koba4329 You can push or pull with a MIG welder. When you pull with MIG you get deeper penetration, however the weld profile isn't as nice. When you push you don't get quite as much penetration, but obviously you get a much better profile. So it all depends on the job, and the finish required, but either work.

[@MilleniumYT1300]

that weld was beautiful it almost looked like tig!

[@tar21gi]

When you pull/drag, where is your gun pointing? It's pointing back at the puddle/weld, which is where the argon/co2 gas is being sprayed at. So yes you can get adequate gas coverage either way, the problem is when your gun angle is too severe, but that can happen with either push or pull, and thats when you can get porosity. If you find yourself getting porosity often, you should straighten your angle a little bit, clean your gun and the metal you're welding on.

@3:05 That weld had to be the display model!!!!!!!!!!!Dam

[@areynolds2000]

I think it has everything to do with the gas flow. If the gas flow is in front of the weld (a push), it shields it more, maybe cooler. The pull would not have as much shielding gas and would be hotter with more penetration. Someone correct me if this is wrong.

@gownozjad3, it is hard to examine many types of weld joints to determine what type of penetration you are getting without destructive investigation. Got to cut it open to view it. Do some practice welds are pieces that are narrow enough that you can take welded assembly over to your cut off saw and cut off some well back into the weld. This is the best and maybe only way to see what kind of penetration you are getting, other than being able to do an x-ray of weld.

[@Koba4329]

@tar21gi alright, thx. will try that. was gettin conflicting stories here but that cleared it up. thx

[@Koba4329]

@tar21gi i was always told that when you pull the argon gas doesn't surround or get trapped around the weld which makes it less strong/less penetration and can cause verocity which isn't even a weld, just makes bubbles and just a completely hollow weld that isn't at all strong. is that true? or just bull?

[@tsraina]

could you discuss multi pass welding and whats the best welder for weldng space frames using 0.120 chrome molly or mild steel.it for my race car/weekend fun car.
I just bought a chicago mig flux core 90amp that says it can weld 3/8 on a single pass
thanks in advance
what a way to test for weld strength I will need in a space frame on chrome molly/mild steel 0.120 tube.its for my tube chassis in my race car/super luxury car.

[@ghowell0729]

@koba4329 it don't matter if you push or pull you'll still get coverage.

[@lassehoei]

@willystylee we not have Idiot stores were i live but i got some from my friend

[@tar21gi]

@Koba4329 oh and also if you get porosity you might need to turn up the pressure on your shielding gas, btw I forgot to set my last response as a reply

[@Koba4329]

k im getting conflicting stories here. im young and learning how to weld from a old pro. he tells me "push a wire, pull a rod" cause when you pull on a wire the gas doesn't stay long enough on the weld for it to seel properly so you get verosity. is that true or is this video true?

[@SthealthRaider]

O M F G!! what can pc arc burn mah eyes?!?!!? OMGH I WATCHED LIKE 1000 hours of welding vids..... WTF

[@Tehtog]

@willystylee This is not true. The computer screen cannot reach the dangerous levels of light. Although you're spot on. A good visor is key.

[@bunnythekid]

I would say push would be deeper.

[@stevebigler]

I was looking for the idiot store, but I could not remember the number for 411.

[@lassehoei]

must i use welding gogles when seeing the video !!!! thxs???

[@SOLDOZER]

Pushing and pulling give the same penetration. Jody from Tips and Tricks proved it. Anyone who says different is just spreading nonsense they heard themselves.

[@joseluislopezfernandez8969]

I'need spanish subtitles please

[@larryalexander4833]

jose luis lopez fernandez this the United States

[@neeedGems]

@willystylee
what the hell.. i never even said this.... o.O

[@Koba4329]

@tar21gi sorry perocity*

[@neeedGems]

yeah u need to, the even looking at an arc on a computer screen will burn your eyes. Better hurry and go get one from the idiot store
