Everything has its own operationrules,The editor of Xinxing recommends that welding personnel understandResistance spot weldingThe change pattern of solder joint nuggets ensures high-quality weldingproducts.
1. The transparent plastic ring was first formed 2. A nugget forms inside the plastic ring 3. The plastic zone and the molten nugget expand simultaneously. 4. The plastic ring can prevent the nugget liquid from being invaded and seeped out by the atmosphere, and prevents splashing.
The expansion speed of the nugget depends on the welding current, and the plastic ring of the transparent protective layer of the nugget has an important relationship with both the welding current and the electrode pressure. When the expansion speed of the nugget is faster than the plastic ring, spatter will occur.
