Schmidt specializes in projection welding machines consumables and accessories. A fourth projection design is the corner projection commonly used to plug a hole in a reservoir.

In most applications one of the workpiece surfaces features multiple small formed projectionsround dimples elongated ridges or rings or the extended corners of weld nuts.
Projection welding weld nut. They can be used in channels and tight spaces where round-base weld nuts wont fit. Ad Find China Manufacturers Of Welding Wire. Projections concentrate the weld and provide room for heat to dissipate.
Projection welding is often used to manufacture weld nuts and weld bolts. Each of our different projection weld nuts have been uniquely crafted to handle their own sets of applications. Short length T joints eg.
Piloted square four projection weld nut. Ad Find China Manufacturers Of Welding Wire. The projections might be round dimples circular elongated ridges or else weld nuts prolonged corners.
Coined projections are common on welding nuts while machined projections often are used to make circumferential projections to form a hermetic seal. The projections concentrate on the current flow once the mating parts are got together. 14 or 15 can be made by forming projections in.
As a result they provide better performance for industrial and heavy duty applications. Projection nut welding is done every day in sheet metal fabrication shops. Projection welding is an ideal method of fastening attachments eg.
The principle applied is the same seen at electric resistance spot welding ERSW but in this particular process the nut has some small protuberances which are. This page introduces projection welding a method that adopts resistance welding principles. Unpiloted square projection weld nut.
There are two round wires put together at 90 degrees form a point contact. Nut welding is used to describe the projection welding process used to attach threaded nuts to a metal substrate. In most tooling is used to locate the nut on the part.
As a distributor for quality-driven companies like SEKI and as a manufacturer of the ProLine Nut Verification System G-Series we have all the tools and equipment you need for an efficient accurate nut welding. The primary advantage of hex-3 projection weld nuts is that you can apply greater torque to these weld nuts as compared to other non-welded nuts. Brackets spigots and weld nuts to sheet metal where there is access from only one side and for making attachments to solid forged or machined parts.
Embossed projection welding and solid projection welding. JHP Fasteners square projection weld nuts are available in several options to specifically suit your project needs. Projection weld nuts provide a high torque value allowing them to withstand heavy duty industrial applications.
That produces heat into these places. Weld them to flat stainless steel surfaces for a strong permanent hold. And that would be the projection weld as well.
Low-Profile Narrow-Base Weld Nuts with Projections. Metallographic aspect of projection welded nut 12 5 times magnification. This is a very common form of welding in the automotive and appliance industry.
This is a projection weld because the nuts either have a partial or full ring projection or multiple corner edges are formed into projections. This method is broadly divided into two types. Projection welds developed via the resistance welding RW process use the design or shape of the part to make discreet individual-point contacts to concentrate the current during welding.
For high-torque applications projection weld nuts show higher resistance to pulling out and twisting. A centering pin is frequently part of this tooling. Projection weld nuts are generally resistant to twisting and deforming when used in higher torque situations.
Piloted square projection JPWP weld nut. Weld sections of typical projection welds are shown in Figure 3. These specialized weld nuts have 3 projections that melt into the host material during the welding process allowing for a fast and secure hold.
