A metal-selected suitable for welding electricallywith low sulphur, carbon silicon andphosphorus, so that the place electri-cally welded becomes stronger than theother sections. The electric-weldedchain does not break at the weld buton the solid part of the link. It has been proved that a chain-bend-ing and electric-welding machine has acapacity equal to the output of tenv orkmen for the quantity. There is theadditional advantage that the rings arelbsolutely similar and the welding of thelntrhest quality without changing theire of the metal. If, for instance, ahand-made chain has a tensile strengthequal to about 55
