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.

Does a hexagonal nut require a higher welding current?

Moreover, the welding current was dependent on the geometric design of the projections. 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.

Sun [4] performed finite ele-ment analysis (FEA) to simulate the projection collapse and nugget formation processes for various projection heights.

How many projections does a weld nut have?

Projection shape varies due to the weld-nut manufacturing method, cost and final product-design requirements. Nuts generally are formed with three to six projections on one side; higher strength applications may require more projections. Projection shape also varies from pointed to rounded with various heights.

About Nut energy storage projection welding

About Nut energy storage projection welding

Projection welding of a weld nut or weld bolt involves three phases. In the first phase, the projection is in contact with the mating sheet. Then the current starts to heat the projection to welding temperature. The electrode force then causes the heated projection to collapse rapidly, and fusion takes place.
