Nut energy storage projection welding

What are the advantages of projection welding of nut?

Since it has the advantages of high production efficiency, no shunting effects, and the ability to arrange solder joints on narrow locations without the limitation of point distance, projection welding of nut has been widely used in the automotive industry.

What type of welding is used for nut and M-thread bolts?

Projection welding is the most common method for nut and M- or T-thread bolt welding. These nuts and bolts are provided with annular projections or three to four separate projections, depending on the application. With an annular projection and a plastic insert, some nut types can achieve a watertight joint.

What nut is used in ring projection welding?

Nut projection welding Ring projection welding 1. Square nut 2. Hexagon pilot nut 3. Round nut 4. Collared hexagon nut 5. T-type nut 6. Cap nut A clearance hole of upper tip is provided, and a breakage of a guide pin and the problem of a spark are remarkably decreased.

What are the welding parameters for a square nut?

For square nuts to BS 7670, the following conditions for welding to 1mm sheet may be used as a guide to setting up:

How complex is the nucleation process of projection welding of nut?

The nucleation process of the projection welding of nut is more complicated. During the tance changes nonlinearly with the contact area. The inter- its state.

Which weld nut has the highest pull-out force?

The annular projection of the high-performance (HP) weld nut required much higher welding current compared to the three and four projections of the hexagonal (Hex) and square (SQ) nuts, respectively. As expected, the highest pull-out force was recorded for the HP M8 weld nut for all sheet materials in the study.
