The work within said heat retaining container is heated by a continuous combustion in a gas burner, so that the temperature of said work is raised to a predetermined preheating temperature. Then, the work is subjected to a soaking treatment at the preheating temperature by switching-over the combustion in the gas burner to a pulse combustion. The continuous combustion in the gas burner is restarted to raise the temperature of the work to a brazing temperature, and then, the part is brazed to said base metal with the temperature of the work maintained at the brazing temperature by switching-over the combustion in the gas burner to a pulse combustion. | |
