Technology

Flash Welding is a Resistance Welding (RW) process, in which ends of rods (tubes, sheets) are heated and fused by an arc struck between them and then forged (brought into a contact under a pressure) producing a weld.

The welded parts are held in electrode clamps,one of which is stationary and the second is movable.

Flash Welding method permits fast (about 1 min.) joining of large and complex parts.

Welded parts are often annealed for improvement of toughness of the weld.

Steels, Aluminum alloys, Copper alloys, Magnesium alloys, Copper alloys and Nickel alloys may be welded by Flash Welding.

Thick pipes, ends of band saws, frames, aircraft landing gears are produced by Flash Welding.
