TacoMitch Posted May 30, 2015 Report Share Posted May 30, 2015 Since there's been so much talk about welders and welding lately I think we should have a thread dedicated to tips, tricks and pics! Post up your pictures of your beads! TIG (600v 1970's Miller arc with a scratch TIG attachment) stainless.

derekmac Posted May 30, 2015 Report Share Posted May 30, 2015 Do any of you guys use the magswitch ground clamps? Link to comment Share on other sites More sharing options...
Powerram Posted May 30, 2015 Report Share Posted May 30, 2015 I haven't used them personally but have seen them used lots, works great for an area that a regular clamp won't clamp to, like large flat surface, pipe, almost limitless uses. But surface has to be clean of rust, paint or clear coat for it to work effectively. Link to comment Share on other sites More sharing options...

My04T4R Posted May 31, 2015 Report Share Posted May 31, 2015 Building the last of the open pit mines in the oil sands, (probably last they are all sagd process now pretty much). Pre building some big *** walls and going to stand the building in sections. But we are doing some heavy duty structural welding here ill try and snap a few tmrw. hosting image Link to comment Share on other sites More sharing options...

derekmac Posted June 2, 2015 Report Share Posted June 2, 2015 So who has tips for welding 20 gauge with flux core? I set the machine per the chart on it, and I could do tacks no problem, but trying to run even a pretty short bead would start blowing through after about an inch of travel. Do you really just have to do really short runs, and move to a different section? I didn't have a need to weld this, just wanted to practice on thin material.

Brunet-Hemi Posted June 2, 2015 Report Share Posted June 2, 2015 Heat at its minimum? If so you might have to either move faster or do many small beads like you were saying. That's some pretty thin stuff. Link to comment Share on other sites More sharing options...

I didn't have a need to weld this, just wanted to practice on thin material. metal that thin pretty much needs to be welded just like you said, the longer the weld the hotter it gets. In practical situations when welding sheet metal you would always want to stagger your welds to avoid warping anyway. You can also use a piece of copper on the backside in certain situations.

flibby Posted June 2, 2015 Report Share Posted June 2, 2015 Here's a tip, read about this in a magazine. don't use brake wash to clean aluminum if tig welding, there is a chemical (I think its tetrachlorethylene or something like that), when its mixed with pure argon and heat it produces phosgene gas which is extremely deadly.

TacoMitch Posted June 2, 2015 Author Report Share Posted June 2, 2015 Don't use brake clean to clean anything before welding!!!! You can use acetone, but in reality a flap disc will work just fine and still give you pretty decent welds. Make sure you clean any paint away from both sides of the metal. As it heats up it'll suck impurities thorough it and give you gross looking welds. When it comes to laying nice strong beads, prep is half the battle.

TacoMitch Posted August 20, 2015 Author Report Share Posted August 20, 2015 Welded up an axle back for the IS at work this morning! I'm not very good at fitting pipes, especially when what I'm fitting isn't here lol I hope it fits! 20150820_042452 by Mitch Parsons, on Flickr 20150820_041608 by Mitch Parsons, on Flickr 20150820_051020 by Mitch Parsons, on Flickr Final-ish product! I have a hole I need to use a mig for, I kept burning through with the Tig 20150820_063119 by Mitch Parsons, on Flickr I didn't purge the pipe before I welded it so there's some buildup of impurities inside the pipe where it wasn't shielded, but at least there won't be any holes!

sar4x4 Posted August 20, 2015 Report Share Posted August 20, 2015 I didn't know what purging for welding was until I watched Extreme 4x4 on Spike recently! Looks like a good first try! Link to comment Share on other sites More sharing options...
