Problems solved by technology
[0004] The main difficulties in the processing of thin-walled pipes are that they are easy to crack, have pressure pits, and are not easy to straighten
At present, under domestic ultra-thin-walled copper-zinc alloys using welding methods such as argon arc welding and submerged arc welding, the finished welds produced are not high in density, wide in heat-affected zones, prone to deformation, low hardness and other welding defects. The appeal welding process has the characteristics of slow welding speed and low production efficiency, which makes it difficult to meet the production needs of ultra-thin-walled pipes

Description
technical field [0001] The invention belongs to the technical field of manufacturing copper-zinc alloy pipes, and in particular relates to a manufacturing method for high-frequency induction welding of ultra-thin-walled H65 copper-zinc alloy elliptical pipes. Background technique [0002] H65 alloy is a copper-based alloy containing zinc. The alloy has high strength and plasticity, and has good cold and hot pressure processing performance, good mechanical properties, good plasticity in hot state, good machinability, and easy welding. , low price and other excellent properties, it is widely used in various stress parts manufactured by deep drawing and bending such as conduits, radiators, pins, and screens. [0003] Copper-zinc pipes have good thermal conductivity, plasticity and high corrosion resistance, and are widely used in electric power, chemical and other industries. For sanitary ware and decorative pipes produced by copper-zinc alloy pipes instead of copper pipes, it...
