hi I am a student (19yr old) going to be working on a Willys CJ2A to bring it back to life the way I want it.

before I dive into the body work I am practicing my welds.
since I am new to body work, I dont really know what I am doing. I know that I dont want to heat up the metal to much or it will warp my body.

should I do a lot of tack welds or do I do constant weld but for a very short bead say 1''.

here are some of my test pieces.
