Typical crack repair involves welding or inserting a string of threaded taper plugs from one end to the other. This is called cold crack repair, and each plug fits into a hole that must be drilled and tapped in an overlapping fashion. Once the plugs are installed, they are ground flush with the surrounding metal. The big limitation to this type of crack repair is access-you have to be able to get into the area with a drill, tap, and grinder. View Related Article
