maximum unit weights of 250 kg, diameter 1,200 mm and
surface dimensions 2,000 x 800 mm, 7 axes simultaneously.
Welding is done manually or by robot welding arms and
using the following welding procedures:
WIG (Wolfram Inert Gas Welding)
Especially for welding high alloy materials and for partly
mechanical welding of aluminium and other non-ferrous
metals.
MAG (Metal Active Gas Welding)
Many assemblies and machines are made of structural
steel. Their solidity depends on impeccable welding seams
which are often genereated using the MAG welding
procedure and the «appropriate» protective gas.
