Influence of stainless steel circular pipes welding methods and parameters to the process accuracy and productivity

This article describes the interacting of AISI 304L stainless steel circular pipes automatic and manual TIG welding method and its parameters to the process accuracy and productivity. Pipe edge preparation described applying seam sequence for manual welding. Length of samples deformation is analyzed and their axial deviation after automatic and manual welding is determined. Basing and measurement principal schemes are presented. The results of measurements are systematized applying appropriate tables with presenting the results analysis. The research is based on experimental results and measurements deleting axial deviation of welded pipes after manual and automatic welding. Looking of best productivity index and welding quality the optimal welding speed and other parameters have been defined experimentally. Further research discusses the possibilities of improvement the productivity index increasing created product and process value.
