Links are flash butt welded. The flash butt welding machine is pre-set according to data depending on chain grade and size (welding recipe). The welding recipe is set by the production engineer and stated in our monitoring system RChain. It is the responsibility of the operator to continuously check that the welding clamps are clean and have a snug fit.

Each flash butt weld is recorded and controlled by microprocessors. The monitoring parameters are the current, voltage, sledge force and position.
