Why are cold-joint welds so difficult to open
One source of difficulty is that cold welding does not exclude relative motion between the surfaces that are to be joined. This allows the broadly defined notions of galling, fretting, stiction and adhesion to overlap in some instances. Cold welding was first recognized as a general. Some will only affect the appearance of the weld, while others may lead to serious issues and eventually result in weld failure. They can start small, on the surface or inside the weld. Since cold welding involves no heat, these issues are avoided. Cold welding produces clean, smooth joints with no oxidation, burning, or thermal degradation. -
