Welding fasteners: Spot or projection? - The FABRICATOR

Spot welding has advantages for hard-to-reach areas. For instance, a spade screw, which has a flat section jutting perpendicularly at the top, can be spot-welded in tight corners and confined spaces (see Figure 4 and 11). Spot welding has a few tendencies to consider. The process can discolor the material, mainly from excessive heat.

How to Weld Cast Iron to Steel | eHow

Welding cast iron to steel is a process that really doesn't take much time to get the hang of, even if you've never welded before. The reason for this is that steel is slightly harder than cast iron, and therefore combines fairly easily. The most difficult aspect of welding is when the cast iron is relatively small or thin compared to the steel ...
