I have to take 4 feet off my car hauler. A section of the tubing is bulging out the sides and i am afraid something very heavy was put on the trailer at that point and damaged the frame tubing. All the other tubing is in good shape. So what i want to do is cut the tubing from right behind the front crossmember and then weld it back 4 feet back. I will also move the bottom "V" portion of the trailer back also. My question is will jsut straight butt style welding it will work?? Originally the front of the box frame, the square tubing was cut at 45 degree angles and welded together. I want to just cut before the crossmember and weld it back ad a 90 degree angle. Sounds confusing I know. I just want to make sure if i weld like this it will be strong enough, i didnt know of the 45 degree cut was done like that for strength or for looks. What do you guys think?? I can also plate the area i reweld so i get some more strength. Or am i overthinking this?? here is a pick of how much i want to remove.
