Nut spot welding machine is used for spot welding nuts, also known as projection welding nuts. Welding nuts can be directly purchased in the market or customized according to requirements. So the question is, can only spot weld nuts with a nut spot welding machine, and can regular nuts be welded with a nut spot welding machine.

螺母点焊机是可以焊接普通螺母的，不过相对于凸焊螺母来说，增加了一定难度。要想焊接普通螺母，并达到螺母焊接的效果，比如焊接牢度，焊接外观，我们还要掌握很多细节。

Nut spot welding machine can weld ordinary nuts, but compared to convex welding nuts, it adds some difficulty. To weld ordinary nuts and achieve the effect of nut welding, such as welding fastness and welding appearance, we still need to master many details.

螺母点焊机点焊普通螺母的注意细节：

Attention details for spot welding ordinary nuts with nut spot welding machine:

要知道，焊接螺母上是有几个倒角的，在点焊焊接螺母的时候，焊接电流会集中在这几个倒角的位置，形成焊接熔核和牢固的焊点，但是普通螺母是没有这个倒角的。

It should be noted that there are several chamfers on the welding nut. When spot welding the nut, the welding current will be concentrated at these chamfer positions, forming a welding nugget and a solid solder joint. However, ordinary nuts do not have this chamfer.

正是因为普通螺母没有这个倒角，螺母焊接的截面积会更大，需要的焊接电流也就更大。苏纳尔工程师提醒大家，常规的螺母点焊参数一般选用硬规范焊接，也就是强电流短时间焊接，这在普通螺母焊接上面是不适应的。

It is precisely because ordinary nuts do not have this chamfer that the cross-sectional area of nut welding will be larger, and the required welding current will also be greater. Engineer Sunar reminds everyone that the conventional parameters for nut spot welding are generally hard standard welding, which means high current short time welding, which is not suitable for ordinary nut welding.

普通螺母的焊接电流要求更大，同时焊接时间也会更长，这样才能为熔核形成提供足够的热量，从而形成稳定均匀牢固的焊点。

The welding current requirement for ordinary nuts is higher, and the welding time is also longer, in order to provide sufficient heat for the formation of molten nuclei and form stable, uniform, and firm welding points.

普通螺母焊接的电极压力不宜过大，这样才能保证足够的电阻热，为焊接电流提供足够的空间。

The electrode pressure for welding ordinary nuts should not be too high, in order to ensure sufficient resistance heat and provide sufficient space for welding current.
