Define Electrical Resistance Welding
About Electric Resistance Welding
It is used for joining pieces of sail metallic or wire. It is a type of pressure level welding. The welding rut is obtained at the location of the desired weld yesteryear the electrical resistance through the metallic pieces to a relatively brusk duration, depression voltage (from half dozen to ten volts only) high amperes (varying from sixty to 4000 amperes) electrical current.
Other details
The total of electrical flow tin endure regulated yesteryear changing the main turns of the transformer. When the expanse to endure welded is sufficiently heated, the pressure level varying from 25 to 55 MPa is applied to the joining expanse yesteryear suitable electrodes until the weld is solid.
Various types of electrical resistance welding are equally follows:
- Spot welding
- Projection welding
- Butt welding
- Roll location in addition to seam welding
- Carbon Arc welding
- Metal Arc welding
- Automatic Hydrogen welding
- Stud arc welding
- Submerged arc welding
