Gripco® Round Weld Nuts | STANLEY® Engineered Fastening

Our round projection weld nuts are engineered for automation and ease of assembly. Round weld nuts yield a better weld schedule and performance than a standard hex weld nut due in part to a larger bearing surface. Three- and six-projection types provide a non-rocking, firm current connection during welding.

The Secrets to Successful Resistance Fastener Welding

The most effective weld controls for projection nut welding are user-friendly, easy-to-understand and intuitive, containing only a few functions required for repeatable and successful welds. In addition, due to their small footprint and thin profile, single-point RPW machines can be combined in cells to create several welds in the same setup

Projection Welding | Application Methods

Projections are "dimples" or "bumps" that are pressed or machined into material at the location where the weld is to be made. Projections promote heat balance, extend electrode life and ensure a consistent current path ensuring more reliable and consistent welds.

What Is Projection Welding? | MachineMFG

The ideal thickness range for projection welding of a plate is between 0.5 and 4mm, while spot welding is recommended for thicknesses less than 0.25mm. With the growth of the automotive industry, projection welding with its high productivity has become widely used in the production of automobile components. 2. Classification of projection welding

Projection Welding of Fasteners to Hot Stamped Boron Steel

In most cases, the weld nuts and studs being used are considerably softer than the 1500 MPa stamping. Due to the large change in hardness, the projections in the fastener will collapse prior to a good weld being made. The end result is usually vaporized projections and extended weld times in an effort to forge the materials.
