ABSTRACT:
In a brazing method of brazing a joint at the contacted surfaces of two base metals, the surfaces of the base metals are arc heated to the optimum brazing temperature of higher than a melting point of a brazing alloy and lower than a melting point of the base metal with the temperature gradient gradually lowering from one end to the opposite end, while feeding the brazing alloy from the end in the lower temperature side into the clearance between the contacted surfaces of the base metals or disposing the brazing alloy in the clearance before heating.
A soft plasma arc is used as the heat source to heat the joint from one end to the opposite end.
