Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular, to a multifunctional welding tooling. Background Art

[0002] In the fields of welding and leak detection technology, especially for the welding and leak detection operations of the carbon dioxide heat pump unit production line, the traditional operation method mainly relies on manual operation, involving multiple links such as oxyacetylene welding, nitrogen protection welding, and nitrogen filling leak detection. However, this operation method has many inconveniences and potential safety hazards.

[0003] First of all, the traditional welding operation requires manually pushing an oxygen cylinder or an acetylene cylinder to the work station and connecting the corresponding pipelines. This operation method is not only inefficient, but also the pipelines are randomly laid at the site, and it is extremely inconvenient to store the pipelines and welding torches when the construction is suspended, consuming a lot of time and manpower. In addition, the continuous welding operation time is limited by the capacity of the gas cylinder, and the gas cylinder needs to be frequently replaced, seriously affecting the work efficiency. At the same time, the height of the gas cylinder trolley is relatively high, posing a potential safety hazard of tipping over.

[0004] Secondly, in the process of internal nitrogen filling protection during copper pipe welding, the above problems also exist. The nitrogen pressure storage tank occupies a large area, which is not conducive to on-site material production management. On the production line with flow operation, it is necessary to move the hand-pushed welding equipment back and forth according to the welding requirements. When multiple sets of equipment are configured, the site is messy, and a large number of gas cylinders need to be managed and their gas types and capacities need to be distinguished.

[0005] Finally, in the nitrogen filling airtightness inspection experiment of heat pump products, similar problems also exist. Manual operation is not only inefficient, but also requires frequent replacement of gas cylinders and dragging of pipelines, resulting in low work efficiency and relatively large potential safety hazards.
