Application of vapor micro-plasma arc welding in air conditioner copper pipe soldering
Copper pipe is a kind of important raw material of refrigeration equipment,and gas soldering is usually used to weld copper pipe joints in production.However,the traditional gas soldering has many disadvantages,so the vapor micro-plasma arc welding process is introduced to explore the feasibility of soldering copper pipes and determine its appropriate welding process parameters.Through the soldering experiments of 5 groups of copper pipe joints with different specifications under 6 welding current gears,the appear-ance and internal structure of the experimental samples after welding are observed,ana-lyzed and compared,which verifies the effectiveness of this method compared with the gas soldering method,and obtains the appropriate welding current gears of various types of copper pipe joints.Compared with gas soldering,better efficiency,stability,ease of use and safety can be achieved by using vapor micro-plasma arc welding process under suitable welding process parameters.
