Description
Summary:Until now, automatic consumable electrode welding in shielding gases has not been used extensively for the joining of non-rotating joints in pipes in nuclear power engineering. This is associated with stringent requirements concerning the preparation and assembly of joints in pipes for welding, the quality of welded joints and the complicated nature of formation of welded joints in different spatial positions. The aim of the present work was the determination of the parameters of microcycles of welding, taking into account the special features of the process of consumable electrode welding with short-circuiting as the preferred method of formation of welded joints situated in different spatial positions.
