Spot welding usually doesn't cause warping. Machining always causes warping. I just straighten them. Even though the liners may be slightly bowed, they will straighten out when the pins are installed. I machined the set in the pictures above and you can see they are parallel after I straightened them.
I machine some of mine if I have the material that's thick enough, but it wastes material. costs more money.
Spot welding allows the use of cheaper materials, but you run the risk of having a spot weld or edge show. That can usually be avoided. I bought a Harbor Freight spot welder on sale for around $100.00 a few years ago just because I wanted to try it on folders.
