How to machine and weld 440B
Thread Content
If this material is used for the valve internals, how should it be machined and welded? The current problem is that conventional cutting tools are difficult to turn and suffer from welding cracks. Is electrical discharge machining really necessary? The machined and welded areas of this part can allow for local annealing, etc.
