METHOD FOR WELDING WIRE ROD

摘要

PURPOSE:To obtain products with stabilized welding strength by preventing the oxidation of a molten metal due to the influence of the air. CONSTITUTION:In the welding method of the wire rod in which two pieces of the wire rods 1, 2 consisting of metal materials are joined by a butt resistance welding, the wire rods 1, 2 are arranged in a reducing gaseous atmosphere such as gaseous hydrogen and the butt resistance welding is performed.
