Description

Technical Field

[0001] The present invention relates to the technical field of reactor welding, in particular to a dual-beam rotary reactor synchronous welding machine. Background Art

[0002] In the fields of chemical industry, pharmaceutical industry, etc., reactors are one of the core equipment, and usually need to weld coils on the outer wall to achieve heating or cooling functions. Traditional external coil welding mostly adopts manual welding or single-beam laser welding technology, which has problems such as low efficiency, unstable weld quality, and poor adaptability. At present, conventional welding equipment usually adopts a fixed structure, which is difficult to adapt to reactors of different diameters and lengths, and the welding gun position needs to be adjusted frequently during the welding process, resulting in complicated operation and difficulty in ensuring accuracy. In addition, when dealing with wide external coils, single-beam welding is prone to problems such as uneven welding and excessive heat-affected zone, which affects the welding quality and equipment life. In the existing technology, some rotary welding equipment realizes circumferential seam welding by driving the reactor to rotate, but generally has defects such as limited adjustment range and low degree of automation. For example, traditional support mechanisms are difficult to quickly adapt to reactors of different specifications, and the position adjustment of laser welding guns often relies on manual operation, which cannot achieve synchronous welding at multiple angles and positions, restricting the improvement of production efficiency and welding accuracy. Therefore, there is an urgent need to develop an automated welding equipment with dual-beam synchronous welding capabilities and the ability to adaptively adjust the reactor size and welding posture to meet the needs of high-precision and high-efficiency welding.
