The Basics Of Welding Part II

Welding is like any other skilled trade—it’s not something you can become good at by reading books or watching videos. It takes practice, experience and some patience (a good name brand machine always helps, too). However, you can gain a lot from reading these tips on welding fitment, machine settings, and eliminate any mistakes that might be made through trial and error. Let’s get welding! 1. This job revolves around making caps for 2x3 box tubing (link crossmember) to give it a nice, finished look. I started by beveling the edges with a 60 grit flap disk on a grinder. This lets the weld penetrate deeper allowing you to grind it smooth without worries of it coming back off.

  |   6. After tacking it on, I noticed that one side was overlapping while the other side was perfect. A little more grinding was in order.

  |   Preparing To Weld 8. Here I am "running it with it" as my dad says. The wire speed is up, and some wrist action is needed here.

  |   Finshed Weld 10. I always choose to take the time to grind the welds down. Hearing protection—you should be wearing it anyway but I feel I can make more precise cuts and have an overall better product without all the background noise.
