Thread: Got the frame cut!

Tweet

good advice guys,
only one thing welding flat is great, but to get the strongest weld they weld up hill. i find up hill and over head are easier.. the 7018 rods i have are in a rod oven..

on the low heat comment. the ovens we use at home and at work are at 350f , so they are perfect for cooking lunch in

i work at power plants and oil refinerys and they xray all our weld so the pressure is on

my dad has a tig and thats the ticket. but if your good you can make a stick weld look as good as a tig.. ive seen guys at work weld tincans together..

When I built my '27 frame I spot welded it and took it to a professional welder. He was referred to me because he teaches welding at a school. I told him I wanted it Migged (that was the high tech 17 years ago) He laughed at me and said he was going to arc weld it. I told him I wanted the welds to be pretty, and he said I would be happy. When I picked up the frame they welds looked like a welding machine had done them. The man was a super good welder, and he was right, I was thrilled. Beads looked like the nickel rows you hear about.

I would have rather seen you make your cut at a 45 degree angle to give more area to your weld.Do you intend to box the spliced area? The last p/u I did,I simply flipped the piece I took out over, overlapped the bottom,and fitted in at the top. i prefer to arc weld this kind of work, dc reverse,90 amps,7018 rod. Hank

I am overlapping the 2 halves 8", and I am going to box and weld the inside, as well as weld fish plates front and back. I am going to use 6" plate across the 8" gap diagonally to give me more area to weld to.

The frame is 1/8", should I use the same for my boxing plates and fish plates, or should I get 1/4 inch?

Use the 1/8th inch. Going to a thicker material just increases the probability of cold welds on the thick stuff or burning through the thinner while trying to get enough heat into the thicker.

Sounds like overkill to me. Why not butt weld the flanges,cut the overlap to a point on the out side,fully weld the inside and outside and then box with the 1/8 in plate. hank

Overkill is kinda what I am shooting for! I have always heard "if you can't weld good weld a lot." If I were more confident in my ability to weld I would engineer a correct kick up, but I am trying to do this all myself, and that is how I feel most comfortable doing it.
