Default My welding projects picture thread

I'm going to throw some pics up every now and then of some of the stuff I'm working on. These are all robot welds, developed and programmed by me. This is the stuff that pays my bills.

Sorry about the bad quality pics, these were taken with my phone and a shaky hand.

Tube welds, can't say what for. .045" wire, power MIG mode, stationary part

The way MIG welds on tube are supposed to look, not the whip/pause "wanna look like TIG" crap so many people are trying to do. :shaking: Leave stacking the dimes to the TIG welders and use MIG like its supposed to be used.



Several more here.

Big crane axle housing. .063" wire. Some CV, some pulse.













10mm fillet on 10mm plate. What a retarded callout by the customer.

10 ton crane front axle housing. Mostly 3/4" - 1-1/4" plate. .063" wire, CV and pulse modes mixed, minimum amperage on any weld seen here is 280, maximum is about 550. A lot of these could look a lot better, but cycle time requirements force me to weld faster than I want to, which sacrifices appearance.

How about a video? This is called "coordinated motion", where the part is moved so that the weld joint stays in the flat position all the way around the circle.

I do like your welds, but you pissed me off with that comment. I have seen some masterful mig welds running stringers with a "whip,pause." motion. these welds are all code welds, most of them are hydro/xray tested. there is NOTHING wrong with that method, I use it myself on pipe quite often.

There are very few people that can do it right, but it can definitely be done. What Im referring to in my comment is all the noobs that like to stack tacks and whip way ahead of the puddle. They have no idea how little fusion and penetration they are getting using that poor technique.

i agree with that but there is nothing wrong with stepping a mig weld. my stepped welds shoot and pass bend tests so they must be done right.
