Abstract

As a new type of pipe

bimetal composite pipe not only ensures corrosion resistance

but also reduces the cost

which has been widely used in oil and gas mining. The welding of bimetal composite pipe requires that the weld has the corrosion resistance of the clad metal and the mechanical properties of the base metal. Automatic welding can improve the welding efficiency and ensure the quality of welding. Therefore

more and more automatic welding technology is applied in the construction of bimetal composite pipe.The paper introduces the application of bimetal composite pipe

the development of welding technology

and the structure characte-ristics of bimetallic composite pipe and the existing problems in welding

introduces the advanced automatic welding technology. Look forward the prospects of development of automatic welding technology of bimetal composite pipe

and provide a reference for automatic welding of double metal composite tube in our country.
