The Z and ZP series resistance spot welders, versatile, robust and easy-to-use, ensure best welding results on all weldable metals. Thanks to their adjustable length feature they represent the ideal solution in a large variety of spot-welding applications. Z models are mechanical pedal operated, whilst ZP's are pneumatically

Resistance Welding has some limitations, the principal ones being: • The equipment has a high initial cost. • There are limitations to the type of joints that can be made (mostly suitable for lap joints). • Skilled maintenance persons are required to service the control equipment. • Some materials require special surface
In resistance welding heat is generated by the electrical resistance of the work pieces and the interface between them. Pressure is supplied externally and is varied throughout the weld cycle. Heat generated is proportional to I2R·t, where I is value of current, R is resistance and t is the time during which current flows.
GENERAL PRINCIPLES. Resistance welding is a thermo-electric process in which heat is generated at the in- terface of the parts to be joined by passing an electrical current through the parts for a precisely controlled time and under a con- trolled pressure (also called force). The name “resistance" welding derives from the.

What is Resistance Welding? Resistance welding is one of many methods of fastening two or more pieces of metal together. Some of these methods are listed below in order to illustrate how resistance welding differs from the others. 1. Bolting. 2. Riveting. 3. Soldering. 4. Arc Welding. 5. Resistance Welding. Bolting, riveting
5.0 Introduction. Electric resistance welding refers to a group of thermo-electric welding processes such as spot and seam welding. The weld is made by conducting a strong current through the metal to heat up and finally melt the metal at a localized point, predetermined by the design of the electrodes and/or the work piece
