PROCESS PARAMETERS FOR CMT ROBOTIC CORROSION RESISTANT OVERLAY WELDING OF WATER TUBE MEMBRANE WALL

Cold Metal Transfer (CMT) welding technology represents an important improvement of classical MIG/MAG welding process. Among its many advantages one of the most important is ease of robotization and automatization. In boiler manufacturing corrosion resistant overlay welding is extremely labour-intensive process. When cladding large areas human workforce would be extremely slow. All these issues can be solved with proper utilization of robotic CMT welding process. This paper will attempt to determine optimal welding process parameters for CMT technology. Stated process parameters are utilised and tested during manufacturing process of water tube boiler membrane walls in Đuro Đaković Termoenergetska postrojenja d.o.o. For the purpose of generating heat water tube boilers often use natural gas as fuel. Manufacturing high quality boiler components represents an important part of natural gas economy
