Description

technical field [0001] The invention relates to the technical field of welding construction equipment, and more specifically, relates to an all-position laser-arc composite welding system for pipes. Background technique [0002] With the rapid development of petrochemical, pressure vessel, pipeline, shipbuilding and other industries, the application of all-position welding technology is becoming more and more extensive. In order to reduce manufacturing costs and improve structural safety, the design of new materials and new structures continues to develop in the direction of high strength and toughness, high pressure, large diameter and large wall thickness, making the whole industry demand high-quality, high-efficiency, low-cost all-position Welding technology has fundamental inherent needs. [0003] Traditional all-position welding mainly uses arc welding technologies such as electrode arc welding, gas metal shielded arc welding, and submerged arc welding. Two sets of co...

AI Technical Summary

Problems solved by technology

However, the existing laser-arc hybrid welding equipment is mainly used for experimental welding of plates, which cannot realize the industrial production of all-position welding of large-diameter and large-wall-thick pipes, and cannot guarantee the automatic control of the all-position welding process, welding quality and efficiency. take into account

[0005] In view of the fact that the existing welding equipment and technology have not yet solved the application and quality control problems of laser-arc hybrid welding in all-position welding of pipes, it is urgent to develop an all-position laser-arc hybrid welding automatic welding equipment
