СПОСОБ ДУГОВОЙ СВАРКИ ВОЛЬФРАМОВЫМ ЭЛЕКТРОДОМ В СРЕДЕ ИНЕРТНОГО ГАЗА

摘要

The tungsten-inert gas (TIG) welding procedure for joining two components and especially an igniter guide (12) to the outer sleeve (11) of a turbojet engine combustion chamber (10), with the guide wall (13) set at an angle to that of the combustion chamber sleeve, consists of moving the welder electrode (22) along the line of the joint so that it lies at an angle of less than 180 degrees to the wall (13) in a direction (D) passing across the corner of the joint. The electrode is supplied with sufficient energy to create a bead in the aforementioned corner. The speed of the electrode's movement and intensity of its current are varied according to the geometry of the components.
