description: The object of the study are samples of 316L stainless steel welded tubes with various cleaning options: after washing, without cleaning and clean. The aim of the work is to study the corrosion characteristics of welded joints, heat-affected zone and the base metal of welded stainless steel tubes. In the course of the work, corrosion tests were carried out for the resistance of welded stainless steel tubes to pitting corrosion. Based on the results of the studies performed, it was found that the studied samples of welded pipes showed low resistance to pitting corrosion. The paper provides recommendations for improving the welding mode to obtain products with improved characteristics and with uniform penetration without defects. The objectives of this study are: 1. Analysis of literature data on existing welding technologies; 2. Analysis of the materials and equipment used for this type of welding; 3. Assessment of microstructure and microhardness; 4. Analysis of the reasons for the formation of defects; 5. Recommendations for improving mechanical properties.
