Abstract
The invention relates to a secondary compression type plasma welding gun. The secondary compression type plasma welding gun comprises a gun cap; the gun cap is connected with a gun body through a fine adjustment centering tube; a gun handle is connected to the gun body. The secondary compression type plasma welding gun is characterized in that a circulating water pipe inlet and outlet joint and a protective gas leading-in opening joint are arranged in the gun handle; an air cylinder is arranged on the upper portion of the gun body. Meanwhile, a tungsten electrode is arranged in the middle of the gun body; compression nozzles are distributed in the lower portion of the gun body. The compression nozzles comprise a first-level water cooling nozzle and a second-level water cooling nozzle arranged on the outer side of the first-level water cooling nozzle; a plasma gas channel is formed between the first-level water cooling nozzle and the second-level water cooling nozzle. Therefore, an electric arc can be secondarily compressed through the two compression nozzles composed of the first-level water cooling nozzle and the second-level water cooling nozzle, and the electric arc is high in concentration ratio and stiffness. The energy utilization rate is improved, economic benefits are increased, and the welding thickness of plasma welding is increased.
