I know this looks like things you can make with a “My first welder” kit, but these are examples of the three basic things that are done with gas welding.

On the left is a box section which is made by welding together four pieces of steel at the corners.

The middle is a butt weld, which I’ve talked about before.

On the right there is a T joint, which I talked about in the last post.

Everyone should try to learn one new skill every year. At least one per year.

Specialization is for insects.
