摘要：
The article studies the change in the content of alloying elements in multi-pass welded joints formed by manual arc welding with TsL-11, TsT-15, and OZL-8 coated electrodes at different currents during welding of tubes made of 12Kh18N10T austenitic steel with a thickness of 6 mm. Based on the results of layer-by-layer chemical analysis of the welded joint metal and base metal, the most efficient welding modes and the sequence of bead surfacing are proposed. Practical recommendations for soft and rigid manual arc welding modes with different TsL-11 electrodes in order to form one- and two-pass welded joints with a uniform distribution of alloying elements are given.
