How do you weld welding projection nuts?

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.

Can nuts be welded?

As a general principle, welding should not be done on bolts or nuts. However, if essential, the composition of the bolt (and nuts if involved) must be carefully considered.” AISI takes the stance that welding to nuts and bolts should be avoided unless absolutely necessary.

Which way do weld nuts go?

You can attach a right-angled weld nut to the base metal to create a threaded hole, which should be aligned vertically to the surface.

What is the purpose of a weld nut?

A weld nut is a special type of nut specifically designed to be welded to another object (spot welding).

What is a projection weld?

Projection welding is a form of resistance welding which uses pressure and electrical current to join two or more metal parts that have been designed to meet at one or more specific points with the maximum amount of contact. This allows for more efficient welding with less energy and greater weld strength.

What grade nut is weldable?

In a random sampling of numerous sizes of nuts in our inventory, representing five different manufacturers, it appears that smaller nuts, those 1″ and below, are cold formed and made from 1008 or 1010 steel, which has low carbon, low manganese, and would chemically be considered weldable.

Is it safe to weld nuts and bolts?

“Occasionally, it becomes desirable to weld bolts to structural steel, or bolts to nuts. As a general principle, welding should not be done on bolts or nuts….When is it acceptable to weld to bolts, and when it is prohibited?

ASTM Standard Recommendations per AISC Design Guide 21
Nuts & Washers Can be problematic

Can you weld zinc nuts?

Yes, zinc bolts can be welded if you follow the proper safety guidelines. Bolts must be appropriately prepared, safety equipment must be worn, and adequate ventilation is essential. We will explain more about the guidelines and preparation so you can safely weld zinc bolts.
