More Spray Arc.

[Guest]

This is an adapter for that stretch bender I worked on last year. All 1 1/2" 1018 cold rolled steel. It has to withstand 135 tons of pressure.

Close up of the joint design.

Here it is all tacked up...just used short arc to tack it.

[Guest]

Another angle of it.

Here it is standing up with the first round of spray arc tacks on it. For these tacks I switched over to spray mode .035" ER70S-6 wire 98 ar / 2 CO2 32 volts, (that's what the meter said by just pulling the trigger, not welding) (I don't think it's accurate) Oh, yeah, the machine is a Miller CP300.

[Guest]

Here's one of the spray tacks....if I had started welding spray arc with it only held by the short arc tacks, it would have popped the tacks, and I'd have a mess on my hands.

[Guest]

Now it's ready to weld, with the 1/16" wire...I'll have to change guns for that. M-25 to a M-40. This is as far as I got today.

VERY nice Rocky !

what does it weigh ? i'd guess ALOT

what kind of designs do you get for the projects you build ?

did the material come beveled on the ends for the welds or did you do that, if so how ? as thick as that is that'd be a fair job with an angle grinder...

It's only about 1800 pounds. I beveled the ends, with a Victor O/A Machine cutter, #2-101 tip.

What do ya mean 'kind of design'? Like blueprints? Acutally, ACAD drawings. A lot of times, I just get a photo of something they want duplicated. If I'm lucky, they will include dimentions.

Yeah, this is the kind of project that I like to see. I am assuming you will be multipassing the joints. If so, could you get some close up pictures of this? I m jealous you get all the fun projects. The thickest material that I ever get to spray arc on is 1/2". Well, I m really looking forward to seeing some more pictures of this project. Hopefully tomorrow evening.

WOW, Rocky. Thanks for posting the joint design. With metal this thick is distortion still a concern? I didn't see any jigs holding it in place. So I assume it isn't necessary.

Thanks

Yes it will move around, but I will weld it to the table to reduce it. I also have a 1" tolerance built in. One good thing is that all the welds are parallel. It will be machined after welding, so it should clean up OK.

Rocky, years ago I had a neighbor who was a Brick Mason. He wanted to start a side line business and someone suggested brick BBQ pits. He made one in his garage that he planned on leaving in the bed of his truck to show prospective customers. Yep, you guessed it. He mortared it to the garage floor. Not the same as welding a project tto the table.
