Metal Finishing Welds On Sheetmetal

[@ttobinupinit]

I've been doing Industrial Metal-Finishing in Wisconsin for the last three weeks. While we don't use exactly the same tools, the same principles seem to translate... I had to struggle for ten hours today, blending the welds on some server racks that we're producing before I realized that the welds were mediocre and not anywhere near full enough to do a proper finishing on. I had to spot-weld (despite having no exerience prior to getting this job) due to the gas pockets that come from crappy welds done by someone with little training more than once (four, in total)... it left me with paper-thin metal to grind and really frustrated me, as it was all done by the overnight shift, which seems to have little training and quality control. Two hours of grinding per piece, when one hour is the norm for an individual piece. The older guys have told me that if I don't get picked up at this place past being a temp, that I should look into working in finishing in the Auto-Body Industry, as I'm already an artist, and my obsessive attention to detail would translate over to that field, as well... I thought it was quite a compliment, as they're all gear-heads, like my Dad, who has built his own Hot-Rods, in the past. I obviously have much more to learn, but decent instruction always starts with the willingness to learn, the ability to take criticism, ask for guidance from those more experienced than you and intellectual curiosity. Thanks for the video, dude.

What a fantastic comment! Thank you, I appreciate it and I apologize for taking so long to reply! It really is too bad when you have to rely on other people to get the quality of work you need. My background is Hot Rods and Customs, so it was stressed on me from the beginning to save as much metal as possible. Thank you for commenting!

Thank you!!! I really appreciate it!

Awesome love this tip. Will try it this weekend

[@MagnaMachineWorks]

Thank you! Good luck with your project!

Ok I have been using this method and it works like a charm. But only have 4 1/2” grinding disc. Where do you find that 3M weld grinder disc? I have been looking, $85 fit one disc seems pricey! Thanks!

@@martinsteele3259 www.grainger.ca/en/product/3X1-4X3-8-ZIP-GR-WHEELS/p/WLT11L333 these should be very similar to what I used in the video. $9.00 CAD each. I couldn’t find the same ones I used, I recently found out 3m may not make that kind anymore.

@@MagnaMachineWorks Thank you!!!

[@MagnaMachineWorks]

@@martinsteele3259 no problem! Hope it helps

What's the part number for that thick 3" grinding disk? Good stuff there!

[@MagnaMachineWorks]

Thank you Roy!

[@vancearamsay]

Where do you buy the discs? This video is awesome. I’ve been wondering why i keep turning my panels to tim foil. Thanks do a great video.

[@MagnaMachineWorks]

Carlson’s body shop supply, Cmax or KMS tools. Thanks Vance!

[@gregtough9055]

Well done!!

[@MagnaMachineWorks]

Thank you!

[@209chevymon]

could i just use a grinding stone and use it the way you used the 3in one to get the same results?

[@MagnaMachineWorks]

@@209chevymon absolutely, you just have to be a little more careful. Lots of power and speed.

[@ChipsAndSparksGarage]

Good technique! Yeah, the thin metal on today’s cars wouldn’t take much to burn through. 👍

[@MagnaMachineWorks]

Thank you!

[@AndyGeesGarage]

Great tips

[@MagnaMachineWorks]

Thanks Andy!

[@maxakarudy]

Completely WRONG mate, pro's use a mini belt sander 3/8" or 10mm. You always gauge the panel with a disc, which ever way you use it

[@MagnaMachineWorks]

Thank you for the comment. I have been an autobody tech for 17 years and have never had the opportunity to use a belt sander. I have only ever done restoration work, I have never done collision work. None of my employers supplied belt sander belts. Saying that, now that I only do this on my own, I am willing to give the belt sander a try. Thank you

[@marialouisa108]

The 1 in. wide belt sanders are GREAT for kissing off the proud weld tops. Then going to a 9in sidewinder w/ 50disc can make short work of going nice. Running disc at 90 to the weld is less effective than keeping it on 180/parallel-cut to the weld line. (I started in 1970, went over to Harrah's car thing in '72, with their old pre-War metalmen ....sorry - using my wife's account this moment... ; - } Kent White )

@@marialouisa108 Kent White!!! Thank you so much for watching and commenting. You are a legend in the industry and I really look up to you. I have recently moved to the 5 inch discs with the backing pad for an angle grinder, trying to continuously improve. I appreciate it
