Production of round link chains
The steel for the round link chains is procured from steel factories, which must meet very high quality and strength requirements. The material for the link is cut to measure by a cutting tool. Along a bending form, the material is bent in two movements into the form of a link and at the same time pressed together.The welding together of the links takes place without the addition of extra material. The side of the weld is given an electric shock, so that this is heated locally. Immediately after that the ends are mechanically pressed into one another and the steel is welded together.After the welding, the chain class is stamped into the chain and the chain is calibrated. During calibration, the chain is pulled to its exact correct length with a force that is 2.5 times the nominal load of the chain. The deformation and the force required are carefully monitored. Thus, in this manner literally every link of a calibrated chain will also be load tested before delivery.
