英文摘要	A new energy-efficient welding method, flux bands constricting arc (FBCA) welding, is proposed to solve the fabrication of metal sandwich panels. This method is suitable for welding T-joints in special structures where the welding gun is unable to reach the welding position, such as welding thick face-plate metal sandwich panels. The characteristics of FBCA welding, key welding technologies, and corresponding defects and resolutions are discussed. Pull-out tests between T-joints welded by laser and FBCA welding were conducted. Results indicate that complete penetration and good fusion of three-sided T-joint can be produced by FBCA welding. The typical cross section morphology is unlike other common welding methods. T-joints without defects, such as weld asymmetry, root leakage, slag inclusion, and pores, show better ultimate tensile strength than T-joints welded by laser welding. The FBCA welding method can compensate for shortage of insufficient weld width of laser welding. © 2019, Springer-Verlag London Ltd., part of Springer Nature.
