FIELD: technological processes.
SUBSTANCE: invention is related to method of arc welding with tungsten electrode in inertial gas medium of the first part with the first wall and end edge to the second part with the second wall and edge, besides both parts are welded to each other along joint surface between mentioned edges, along which the first wall creates a protruding angle with the second wall. Electrode is moved along mentioned surface. Electrode is placed on side of protruding angle at the angle (β) of less than 180° relative to the first wall, at the same time in case of this direction (D) electrode passes through incoming angle joined to protruding angle.
EFFECT: method is used, in particular for welding of guide spark plugs to jacket of gas turbine engine combustion chamber.
