Product Details
Tungsten copper welding wheel is know as rolling welding wheel, which is a kind of electrode wheel mounted on seam welder. Becasue of its good wear resistance, electrical and thermal conductivity can be widely used in steel, stainless steel, copper, aluminum and other materials welding.
Seam welder is similar to spot welder, but there are some differences in the shape of elctrode. The electrode of spot welder has rod-like electrode and spark welding, but the seam welder has two upper and lower ring-like electrodes and continuous or intermittent dischargeing.
Tungsten copper welding wheel is suitable for the continous welding in metal sheet joints, such as soldering iron tin cans. In the welding process, upper and lower ring-like electrodes clips the welded workpiece, the welding wheel plays a part of electrode and were released by being positive and negative current welders, welders are in contact so that the heat generated will be fused welder parts. And the rotation of the roller drives welders to form a continuous welding process.
Tungsten copper welding wheel are indispensable in PCD sharpening and other precision applications, thanks to their unique combination of wear resistance, thermal conductivity, and high electrical conductivity. Their role in the EDM process for eroding hard metals and PCD components ensures high-quality results in industries such as aerospace, automotive, and semiconductors. As advancements in metallurgy and manufacturing processes continue, copper tungsten electrodes will remain a vital tool in achieving high precision and performance across demanding applications.
