 The invention discloses a consumable electrode inert gas shielding arc brazing process for a titanium alloy-stainless steel. The consumable electrode inert gas shielding arc brazing process for the titanium alloy-stainless steel comprises the following steps that firstly, welding pretreatment is carried out, wherein edge machining of titanium alloy base metal and stainless steel base metal, surface washing of the titanium alloy base metal and the stainless steel base metal and assembling of the titanium alloy base metal and the stainless steel base metal are included, and a dry low-melting-point welding stick is selected; secondly, in the welding process, welding is carried out through a consumable electrode arc method, firstly, the low-melting-point welding stick is arranged at a position, to be welded, of the titanium alloy base metal and the stainless steel base metal and points to one side of the stainless steel base metal, the offset is 0 mm-1 mm, in the welding process, a weldinggun is controlled, and inert gas is used for protecting a welding region; and thirdly, welding aftertreatment is carried out, and a fixture is immediately loosened after welding. By means of the process, the strength and the tenacity of a stainless steel and titanium alloy joint are improved, the process is simple, the production cost is low, the production efficiency is high, and the applicationprospects are wide.
