Prompt rationing of MIG/MAG welding works in series production

Abstract

The research on welding work in the conditions when products of different sizes, shapes and complexity are manufactured in series is performed in the work. The professional skills and abilities of welders of various qualifications in the production of parts with MIG/MAG technology have been tested. Video recordings of welding processes of various products have been collected and analyzed. The results of the observations were used to determine the time capacity of the welding work elements and to model the course of welding work. The aim is to find out the possibilities to calculate the time required for welding a specific product, using the test results and the technical documentation of the product. The dependence of individual elements of welding work on various factors is analyzed. An algorithm for calculating the welding time of different types of products has been developed. A method for determining the welding time for groups of products of different complexity by the welding angle and joint seams with MIG/MAG technologies has been developed. Theoretical calculations for the welding time of various parts have been made. Time consumption for analog parts was determined experimentally. The results were compared using mathematical statistical methods. It has been found that the technology used for the standardization of welding work allows to calculate the time required for welding the product with acceptable accuracy, using data from the technical documentation on the length of the seam, the number of parts and the cross-sectional area of the seam.
