A three-dimensional automatic welding system and its welding control method

Abstract

The invention discloses a three-dimensional automatic welding system. The three-dimensional automatic welding system mainly comprises a welding gun running mechanism, a control cabinet (21), a welding machine and a wire feeding machine, wherein the welding gun running mechanism comprises a swing mechanism, a lifting driving mechanism, a direct movement mechanism and a base (1); the movement direction of the swing mechanism, the movement direction of the lifting driving mechanism and the movement direction of the direct movement mechanism respectively correspond to the X-axis direction, Z-axis direction and Y-axis direction of a three-dimensional orthogonal coordinate axis. The invention discloses the control method for welding by use of the three-dimensional automatic welding system, and the control method can be implemented under an automatic control or a manual mode. The three-dimensional automatic welding system is applicable to multi-layer welding of medium-thickness walls and long straight seams, can be used for realizing automatic welding, and is low in manufacturing cost, convenient to use, stable in welding quality and relatively high in efficiency.

Description

technical field [0001] The invention relates to a three-dimensional automatic welding system and a welding control method thereof. Background technique [0002] With the rapid development of science and technology in today's era, welding, as a key manufacturing technology, has entered a new stage of development. Many of the latest scientific research achievements, high-tech Technology and cutting-edge technology are constantly fused in welding, and a variety of straight seam automatic welding equipment has emerged in large numbers. The torches of these straight seam automatic welding equipment are mostly raised and lowered by cylinders, and the height can only be fine-tuned by mechanical fixtures, which are only suitable for thin-walled single-layer welding of (0.5-6) ​​mm. In construction, petrochemical, construction machinery and other industries, with the increasing demand for large-scale welded structures, the application of multi-layer multi-pass welding of medium and ...

AI Technical Summary

Problems solved by technology

At present, the domestic medium-thick-wall welding method is mainly multi-layer and multi-channel MIG welding. Generally, manual welding or semi-automatic welding is still used. The welding efficiency is low and the labor intensity of workers is relatively high.
