We investigate laser bonding of Zr 41 Ti 14 Cu 12 Ni 10 Be 23 bulk metallic glass (BMG) using experiments and finite element simulation. The specimen plates with 5 × 30 × 1.3 mm 3 are welded together successfully and the welded joint maintains fully amorphous under the welding parameters of 1.3 kW and 7 m min −1 . To examine in detail the thermal stability of the welded joint, we employ the SYSWELD software to simulate the distribution of temperature field and thermal cycle curves. The simulation results are consistent with the laser welding experiments, and there is no intersection point between the thermal cycle curves and time–temperature‐transformation diagram, indicating that the joint retains amorphous structure.
