TIG welding head with multi-axis servo movement mechanism and welding method

Abstract

The invention discloses a TIG welding head with a multi-axis servo movement mechanism and a welding method. A walking mechanism is installed on a walking track so that the TIG welding head can move along the walking track. A wire feeding mechanism is installed on one side of the walking mechanism and used for feeding a welding wire when the TIG welding head performs welding. A swinging mechanism is fixed to the upper portion of the walking mechanism and connected with one side of a vertical adjusting mechanism through a welding gun angle adjusting arm, the other side of the vertical adjusting mechanism is connected with a front-end welding mechanism, and therefore a welding gun can swing in a reciprocating mode in the width direction of a welding seam when the TIG welding head performs welding. The vertical adjusting mechanism is used for adjusting the distance between the welding gun and a workpiece. The front-end welding mechanism is used for adjusting the position of the welding wire and the position of a tungsten electrode. The TIG welding head is economical, practical, compact in structure, small, portable, convenient to clamp, convenient to disassemble and maintain due to modularization, high in automation degree and capable of achieving remote monitoring and control in the welding process.

Description

Technical field [0001] The invention relates to a TIG welding head with a multi-axis servo motion mechanism and a welding method, and belongs to the technical field of automated welding equipment. Background technique [0002] With the vigorous development of national industries such as nuclear power, petrochemicals, and wind power, welding, as one of the most widely used permanent connection methods, is widely used in the equipment manufacturing, installation, and maintenance processes, and whether we can obtain high-quality welded joints directly affects Ensure the engineering construction and operation safety of equipment. At present, narrow gap welding TIG welding technology has been widely used in the manufacturing, installation and maintenance processes of these equipments. At present, the level of domestic narrow gap automatic TIG welding equipment is constantly improving, but there is still a gap in technical level and performance compared with foreign countries, es...

AI Technical Summary

Problems solved by technology

At present, the level of domestic narrow-gap automatic TIG welding equipment is constantly improving, but there is still a gap between the technical level and performance compared with foreign countries, especially in practical applications.

[0003] Narrow-gap TIG welding technology and equipment are still in the research stage in China. At present, the narrow-gap TIG welding mechanisms developed by several domestic companies either have a low degree of automation, high labor intensity for operators, and cannot realize remote monitoring and control; or The mechanism is complex, heavy and bulky, which cannot meet the welding requirements of small-pitch tube rows
