Undercut created during welding. In welding, undercutting is when the weld reduces the cross-sectional thickness of the base metal. This type of defect reduces the strength of the weld and workpieces.
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.
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 ...

Autogenous welding is a form of welding in which the filler material is either supplied by melting the base material or is of identical composition. [1] The weld may be formed entirely by melting parts of the base metal, and no additional filler rod is used. There is some variation in the use of this term.

Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935.
Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates.
