Seam Welding Electrodes

Seam welding produces an extremely durable weld because the joint is forged due to the heat and pressure applied. A properly welded joint formed by resistance welding can easily be stronger than the material from which it is formed.

The electrode wheels apply a constant force to the work pieces and rotate at a controlled speed. Seam welding equipment is normally fixed and the components being welded are manipulated between the wheels.

Spot Welding Electrodes

Resistance spot welding is a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. It is a subset of electric resistance welding.

Work-pieces are held together under pressure exerted by electrodes. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time.

Mesh Welding (Cross Wire) / Butt Welding Electrodes - Parts - Blocks

Cross Wire Welding Is a process for joining bars or wires in cross joints by directly applying opposing forces with usually flat electrodes. The current and the heat generation are localized at the contact points of the crossed bars or wires. Cross wire welding is widely used in construction and electrical industry as well as for manufacturing of metal wire nets and shopping trolleys etc.

Butt welding is a precess where two pieces of metal to be joined are in the same plane. These types of welds require only some kind of preparation and are used with thin sheet metals that can be weldedwith a single pass.
