66 cj-5 frame welding questions

Thanks Dave, but I am well versed in mig, tig & stick, been behind a hood since 1972. The only welder I have available is my pipeliner and that is why I was asking about the diffeences between the 2 rods is in post #6. Jim

That was a typo. It is a 1966 CJ5.

get a buddy to weld it a welder who dont know how to weld is like a murder wepon lol

 

hey cj-jim
preperation is everything! use fresh 7018 rod. remove all paint, scale and grease. don't bother with grinding a bevel, the material is thin enough to weld one side then grind out the backside to clear metal then weld it. you will achieve a full pennetration weld using this method. definitly pre-heat the area to be welded and when you are done wrap it with a welders blanket. this will help minimize problems in the heat affected zone. before you attempt the welding i would suggest mocking up a test sample that as closely resembles the actual weld as possible and weld in the exact position that you will be doing on the frame. take a look through a very critical eye and be honest with yourself as to the quality. if you have any doubts maybe have a pro do the job. if you are going down the road at any speed and the weld fails you and any oncoming traffic might not fare so well. good luck!

 

Thanks Skeely, you confirmed my thoughts on what I was taught on frame welding, be it truck, tractor, car or whatever, except for the welding blanket to hold the heat, I did not think of that one. Thanks again everyone for your input. Jim
