Abstract With the rapid development of industry and globalization, the demand and strategic importance of oil and natural gas have become increasingly significant, leading to energy extraction in more complex corrosive environments [1, 2]. Bimetallic composite pipes, which offer strength and corrosion resistance, exhibit promising potential. For the welding of bimetallic composite plates, it is optimal to follow the welding sequence of the base layer, transition layer, and inner layer [3, 4]. For the welding of bimetal composite pipes, due to the diameter limit, the inner layer is usually welded first, followed by the transition layer,… More >
