in order to improve the performance of the welded joint of the identification machine, it is sometimes necessary to add one or more of the following items to the basic cycle:
(1) increase the pre-pressure of the indentation machine to eliminate the gaps between thick workpieces and make them fit closely.
(2) use preheat pulse to improve the plasticity of the metal, make the indentation machine work piece fit easily and prevent spatter; indentation machine protruding welding can make multiple bumps evenly contact with the flat plate before welding, to ensure each point the heating is consistent.
