Abstract
Butt-welding procedure can be used for the welding of pipes, sheet metal, rails and the like, and the burn off rate is altered during welding. The welding process is completed before the entire surface of the front face has reached a temp. of 0.7 - 1.0 of the melting temp. of the material to be welded. Max. output performance is maintained as a function of the current flowing through the primary circuit of the welding transformer, while the products are upset to an extent equal to the distance between the cross-sections of the products when heated to a specific temp.
