摘要
Abstract
LNG storge tank is core equipment of LNG storage and transportation and its construction technology is complex and strict. The welding technique of tank wall plate with 9％ Ni steel is the key of the construction of LNG storage tanks at low temperature.The welding joint is directly connected to the tank's construction quality, safety and reliability.The paper focuses on applications of SMAW and SAW during the construction of tank wall plate, including the choice of welding materials and parameters, designing welding groove,welding sequence and procedure specification. SM AW is applied to vertical position welding,and SAW is applied to horizontal position of girth welding. Welding procedure qualification is carried out and the properties of joints are measured.The results show that two weld joints are qualified.关键词
