Abstract

The invention discloses a welding device, relates to the field of welding and aims at improving the quality of welding. The welding device comprises at least two welding electrodes and at least two transformers, wherein each transformer corresponds to one welding electrode, and the rated power of each transformer is lower than a set value. Compared with the prior art that the welding electrodes are driven by a high-power transformer, the welding device is provided with a plurality of welding electrodes and each welding electrode corresponds to one independent transformer, and therefore, a low-power transformer can be adopted. Taking the high-power transformer of above 200KVA in the prior art for example, a common transformer of below 200KVA can be adopted. As a result, the power of the transformers of the welding device can be extremely low, and therefore, the phenomenon of unstable welding quality due to great power grid current fluctuation can be reduced and even avoided.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding device. Background technique [0002] The welding equipment currently used is a multi-point spot welding machine. Existing multi-point spot welding machines all use a high-power transformer to drive a plurality of spot welding poles for welding. This welding device has the disadvantages of large grid current fluctuations and unstable welding quality. Contents of the invention [0003] One of the objectives of the present invention is to provide a welding device for improving welding quality. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] The invention provides a welding device, comprising: a welding electrode and a transformer; [0006] The number of the welding electrodes and the transformers is at least two, and each of the transformers corresponds to one of the welding electrodes; [0007] Wherein, the ra...
