[0001] The invention relates to the technical field of welding fixtures and metal welding, in particular to a welding fixture and a welding method for furniture metal components. Background Art

[0002] The welding of furniture metal components is an important link in the manufacturing process of metal furniture. It involves a variety of welding methods and precautions. Metal accessories in metal furniture, such as support columns, mainly play a supporting and load-bearing role. In order to facilitate the subsequent assembly of support columns with other accessories of metal furniture, multiple connectors are usually welded to the support columns to facilitate subsequent connection and assembly.

[0003] During the welding process, the existing welding facilities can only weld and fix one connecting piece to the support column at a time. It takes a long time to weld the component and the support column together, resulting in too slow processing efficiency and unable to meet user needs.

[0004] The reason for this problem is that the welding device can only weld one component to the support column at a time. The welding process is to first fix the component and the support column, and after welding, release the clamping parts, then clamp the new component and continue welding. This leads to a high repetition rate of the entire processing flow, which limits the welding speed and makes it impossible to weld quickly. Therefore, we propose a welding tool and welding method for furniture metal components to solve the above problems. Summary of the invention
