    My job literally trained me for a day yesterday and just said if it's not shiny it still needs grinding and that was it .... Thank you for this knowledge !

      Ive been a fab worker for 25 years and my son texted me asking for help with this at his new job. Im off site now for QC inspection and travel so i found this video and sent it to him. Its very sad to hear from him and from you that people still dont want to teach new trades workers the job. The industry is starving for new hires but the old guys like me dont want to teach its very sad.

    I had a lot of old pipes and rebar to cut up and from what I read ua-cam.com/users/postUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.

    I worked for 2 abrasive manufacturers for over 40 years and have visited literally thousands of manufacturers fabricating many types of steel, stainless steel and fibreglass products. This video demonstrates various levels of grinding and finishing abrasives but should not be seen as a “how to” instructional on finishing light structural steel. I never saw anyone using non woven Velcro discs of fine grit orbital psa discs to blend welds on light angle iron. My recommendation would be to use a 60 grit flap discs for this application.

      I have seen people reuse discs by cutting down the pads and disc 1/2" around. Making a set for my roloc discs so i can reuse the edge until i get to 1" size. So 3 inch, 2.5 inch. 2 inch, 1.5 inch, 1 inch, .5 inch all the same disc passed down the line to use it up completely. of course i dont use them all in order as it takes a time to switch the bits. just do all 3" until u run out. then go to all 2.5 etc.

    i recommend you try anti vibration backing pad from Walter or off shore brand. the one you demo is very good for stainless but it does a number on wrist. i can only one hand grind with that kinda pad for like 10 minutes. well with anti vibration i can grind for 8 hours everyday one hand.

    I wish I could weld as good as your welds look. I enjoy welding on projects that come my way , but that is not all the time. In order to make my welds look better I spend a lot of time grinding them down. I have found that a 36 grit zirconium flap disc cuts through welds fast and they last for ever opposed to other flap disc's.

    If you have a good hard and wear resistant stone on a die grinder and a light touch, you can do tight spots, and it won't be too chewed up - might not even need a sanding pass if it's fine enough a stone

    Clamp a piece of brass flat stock, like 1/2 × 1 1/2 on backside, and weld with a little more penetration. It will remain smooth on backside.

    Isn't that 1/4" thick wheel supposed to be used for end grinding, using the flat edge of the wheel only? I would have knocked the weld down using just the edge and use a 2" sanding disk to blend. If filler would be needed, only a fraction of the area would need to be filled to blend with the parent surface.

    Are there cons or benefits to using sanding discs vs flap wheels?

    • @robdamico5304
      @robdamico5304  5 років тому +1

      The flap wheels are more expensive but last longer. The sanding discs are cheaper per pad but you also need to buy a backer. In terms of finished part results, the sanding disc is more flat, and if your technique is on point you can get a very flat (nearly invisible) weld seam. The flap discs are inherently curved and generally a bit more spongy. I find it’s harder (nearly impossible) to get a flat grind with a traditional flap disc. However, if you don’t need a super flat weld seam, perhaps you just need a smoother weld seam or a rounded corner/edge, a flap wheel will save you a good amount of time and effort.

      Fiber disc will get you flat surface, flap discs will just remove the weld make surface not flat and take out all of your sharp corners....also you both need cubitron 987 discs, this klingspor are bad as soon as they touch metal
