Welding method

Abstract

A welding method includes perpendicularly connecting a web required to be welded with a mother board; setting different welding parameters of two side surfaces, connected with the mother board, of the web according to the thickness of the web and welding sequence of the two side surfaces, connected with the mother board, of the web; selecting deflection distance point as a welding position of a welding gun according to the thickness of the web, adopting a connecting line of an optional side surface, connected with the mother board, of the web as an x-axis, adopting a line perpendicular to the x-axis as a y-axis, and adopting an intersection of the x-axis and the y-axis as an original point; and welding at the selected position by a 45-degree ship-shaped welding mode. The deflection distance point is centered at the original point upwards along the y-axis. By the aid of the welding method, the problems that a traditional T-shaped full-penetration weld joint method is over complicated in process and high in auxiliary material consumption, accordingly, production efficiency is low, requirements on personal experience and self-technique are high, the qualified rate of products is greatly affected by the technical level of workers, and a large-scale processing mode with multiple production lines cannot be realized are solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding method. Background technique [0002] With the continuous development of the steel structure market and the optimization and integration of the steel structure market, higher standards and stricter requirements have been put forward for the production and manufacture of steel structures. Some traditional welding processes can no longer meet the needs of market development. [0003] The traditional T-shaped full-penetration weld method usually requires the following six processes: cutting the web before welding, gap assembly, gas-shielded welding priming, back gouging, gas-shielded welding, submerged arc Welding etc. procedures. This method requires six processes, which makes the process too complicated and consumes a lot of auxiliary materials, resulting in low production efficiency; at the same time, this method requires high personal experience and skills, not only...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a welding method, which solves the need for six processes in the traditional T-shaped full penetration weld method, which makes the process too complicated and consumes more auxiliary materials, resulting in low production efficiency; The experience and skills required are relatively high, not only requiring workers to have a high level of gas shielded welding skills but also rich experience in gouging and root removal. The technical level of workers has greatly affected the product qualification rate, and it is impossible to achieve a large Problems with processing methods in batches and multiple production lines
