[0002] The flow channel and pipeline welding equipment of the cooler is a key equipment specially used for the manufacture and maintenance of the cooler. It can firmly weld the various flow channel and pipeline components of the cooler together to ensure the normal operation and efficient heat exchange of the cooler.

[0003] When using existing welding equipment, most operators hold the welding equipment in their hands to perform welding work, which results in poor fixing effect on the parts to be processed, easily causing the parts to shake and cause welding errors, while reducing the welding efficiency of the welding equipment. Moreover, if the equipment is not polished before welding, impurities such as oxide layer, rust and oil stains will remain, which are easily mixed into the weld, resulting in welding defects such as pores and cracks. These defects will seriously affect the strength and sealing of the weld. The presence of impurities will also reduce the strength of the weld, making the weld prone to breakage when bearing loads, thereby affecting the safety and reliability of the welded structure. Currently, manual polishing is usually required before welding, and fine cracks cannot be found, which greatly reduces the welding efficiency and quality.
