Brazing a car frame

Oct 18, 2013 3 Replies

I am contemplating building a t bucket. I have plans to build a frame out o f 2x3x 3/16 rectangular mild steel. I consider myself a "farm welder" I can make it hold, but it is not real pretty. On somethign like a car frame, I wondered for someone worried about their welding would brazing be better? W ould the capillary action be more "idiot" proof for lack of a better word? I have read brazed joints can be as strong as welded joints.



Again, just brainstorming right now and contemplating options.


A properly designed and properly executed brazed joint may well be as strong as a welded joint.... but note the word "properly".

But why not just get some 3/16" plate and practice up a bit so that you are sufficiently expert to weld the frame?

At night class in the high school shop we bent our practice coupons between three pieces of scrap on a 50 ton hydraulic press, but Vise-grips and a bench vise will do for 1/8" steel. . I didn't start my project, a hydraulic bucket loader for my tractor, until my arc welds with 7018 would stand being bent double. jsw

I currently have a hobart 110 mig that can use flux core or gas. Would this be sufficient for 3/16?

Also, I can weld with it but have never done anything "critical". I have re ad alot about welding but have difficulty "seeing" from what I have read de fective welds such as undercutting, convex, concave beads etc. I do know wh at porosity is.
