Which stud welder is best for sheet metal?

State-of-the-art solid-state capacitor discharge stud/pin welders, featuring lightweight design for increased portability and power. The ProWeld ® Table Welder is perfect for welding sheet metal with CD studs or headed anchors. ProWeld's AG line of drawn arc stud welding tools are lightweight, compact, and powerful.

Is hilumin a good weld?

Hilumin, a nickel-plated steel product by Tata Steel , and CuZn37 specimens according to Fig. 2 were investigated. For both metals a proper weld cannot be achieved with too little welding energy, in this case less than 200 Ws (see Fig. 6). More welding power enlarges the weld nugget and leads to a higher weld quality.

How do you find the optimal weld seam?

The optimal geometry of the weld seam for the used test samples is given by the edges transversely relative to the longitudinal direction of the overlap . The optimal weld seam can be realized by laser beam welding resulting in relatively low electrical contact resistances.

Do voids inside the weld Nuggets reduce the strength of a joint?

The voids inside the weld nuggets for spot-welded CuZn37 test samples reduce the strength of the joint. But for spot-welded Hilumin test samples the base material failed and not the weld spots themselves (see Fig. 6). This was only observed with resistance spot welding.

What stud welding accessories do you offer?

We offer a full line of standard in-stock fasteners for quick shipment, as well as custom-designed fasteners to meet your specific needs. To support our complete line of stud welding equipment, we offer a wide variety of stud welding accessories, including chucks, grips, feet, insulation pins, and more.

How does welding energy affect electrical contact resistance and tensile force?

Further increasing the welding energy leads to electrode sticking and significant expulsion of bulk material , , , . Fig. 6. Electrical contact resistance and ultimate tensile force as function of welding energy.
