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.
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.
Attention details for spot welding ordinary nuts with nut spot welding machine:
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.
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.
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.
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.
For more nut welding issues and knowledge, you can consult Sunar technical personnel at any time. Professional technical advice can help us better complete nut spot welding operations and also save a lot of time and cost.
