I really had my doubts that this was going to work. Lincoln's L-56 .035 inch wire on 1/2 inch thick material. I cut the bevels on the coupons at 37 1/2 degrees. I ran this at 18-volts, 198 wire speed, 125-amps, with 20 cfh of C/25 gas. I know a lot of charts say you can use .035 wire on 1/2 inch plate, but I didn't think it would work. Years ago one of the best weldors I ever had the pleasure of working with spliced some 3/4 inch thick plate using .035 wire, mainly because he was too lazy to change wires. When the plates were tested they failed!

These coupons were side bends, someone told me once a side bend test is harder to pass than a face and root bend. I don't know if that's true or not.


















No visible flaws.

Thanks! I tried something new, I ran the root and hot pass using the upside down V like in this video.

He,He. And I thought somebody was just asking if it could be done. Very nice looking and the cutaways are even more impressive. I prefer to run vert up with my mig also. It has been years since I have done any bend tests. Kinda miss welding, my new tractor has given me a chance to start again. I have not done any fab work since building a bunch of wood boilers 4 years ago. Reinforced my bucket and added hooks last night, the fork rack will get hooks tonight. Also will start on a carry box.
