The work is dedicated to increase of safety and service life of apparatuses of chemical production due to replacement of brazing process to welding in manufacture of the filter elements. Three methods of welding (argon arc, electron beam and laser) were compared applicable to joining of thin-wall tubular cone billets for the filter elements of stainless steel 08Kh18N10T steel. Defects, typical for indicated methods of welding, were investigated and procedures for their elimination were proposed. It is determined that laser welding has the largest productivity in combination with high weld formation stability that makes its application reasonable as industrial technological process in manufacture of thin-wall cone filter elements. 9 Ref., 5 Figures.
Keywords: stainless steel, thin-wall products, laser welding, productivity, edges, technological fixture, mechanical properties, corrosion resistance
