In manufacturing, an undercut is a special type of recessed surface that is inaccessible using a straight tool. In turning , it refers to a recess in a diameter generally on the inside diameter of the part.
Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
Shrinkage then introduces residual stresses and distortion. Distortion can pose a major problem since the final product is not the desired shape. To alleviate certain types of distortion, the workpieces can be offset so that after welding, the product is the correct shape. [19] The following pictures describe various types of welding distortion ...
