Flat Head Rivets

Flat head rivets are cylindrical bodies without threads and with smooth surfaces, specifically designed for standard arc welding processes. The interior of the welding end is filled with a soldering agent, which can make the welding process smoother and meet various usage requirements.

Product Features

The rivets are just a metal rod, with one end designed for welding to steel. You can attach them to the surface using a welding gun. The electric arc produced by the welding gun will melt the bottom of the pin and the underlying metal, instantly fusing them together. This is a method that allows for the quick addition of installation points or anchors without the need for drilling.

When conducting insulation on the steel bulkheads of ships, using flat head rivets can save several hours. Using a standard arc welding machine, hundreds of pins are spot-welded onto the metal. The pins protrude, and all that is needed is to place a fiberglass pad on top of them and cover it with a washer. No drilling or use of adhesives is required. It can withstand the high temperatures and vibrations of the engine room and will not malfunction.

Most welding rivets are made of carbon steel, but there are also ones made of stainless steel, which are suitable for corrosive environments such as food factories or ships. The material of the welding pin should match the base material. Although it is possible to weld stainless steel onto low-carbon steel, it may rust over time. Copper welding pins are rare, but are often used for grounding.

Installation Advantage

Flat head rivets can be installed using standard arc welding techniques. During the welding process, the welding gun lifts them from the surface of the base material. The power supply generates a controllable electric arc, which melts the ends of the weld pins and a portion of the base material. Then, the weld pins are pressed into the molten metal, thus forming a high-quality welding joint. They can withstand considerable tensile force and pressure.
