Welding represents the joining of two workpieces in a liquid state. The welding stock and the welding rod are made of the same basic material . The weld point is briefly brought to melting point and the materials more or less flow into one another.

The welding temperature is usually produced by a light arc (arc welding). In the rarer process of oxyacetylene welding, the heat is produced via a flame. Other welding processes include friction welding and spot welding.
