Resistance Welding Diagram. 229 high frequency resistance welding of thin walled pipes the high frequency resistance welding process can be used to weld many types of steels copper and its alloys aluminium nickel and its alloys titanium and zirconium. Included spot welding and seam welding two joining methods widely used today in sheet metal working.
Resistance welding processes are used to join metals and include spot welding seam welding flash welding and projection welding. Heat i2 x r x t x k where i is the weld current through the workpieces r is the electrical resistance in ohms of the workpieces t is the weld time in hertz milliseconds or microseconds and k is a thermal constant. Resistance welding working principle diagram process.
The general heat generation formula for resistance welding is.
The name resistance welding derives from the fact that the resistance of the workpieces and electrodes are used in combination or. This is the same principle which is used in the electric coil. Heat i2 x r x t x k where i is the weld current through the workpieces r is the electrical resistance in ohms of the workpieces t is the weld time in hertz milliseconds or microseconds and k is a thermal constant.
