摘要（英）：

Disclosed is a method of gas turbine combustion chamber stellite alloy bead weld. The invention relates to the method of combustion chamber stellite alloy bead weld, and provides the method of the gas turbine combustion chamber stellite alloy bead weld which aims at solving problems that weld joint strength and anti-cracking ability of the gas turbine combustion chamber stellite alloy bead weld not comply with the design requirements, and safe operation of a unit is unsteady. The method of the gas turbine combustion chamber stellite alloy bead weld comprises the following steps of (1) cleaning welding areas of workpieces, (2) heating the workpieces by using kiln equipment, (3) welding the satellite alloy on the workpieces by using a direct current argon arc welding machine, (4) carrying out heat treatment on the workpieces after the workpieces are welded with no flaws, namely achieving bead weld of the gas turbine combustion chamber stellite alloy. The method of the gas turbine combustion chamber stellite alloy bead weld is applied to the field of the gas turbine combustion chamber stellite alloy bead weld.
