Twin-Wire is the Latest in Weld Overlay Cladding
01 Mar 2006
Weld overlay cladding (WOC) specialist Arc Energy Resources has announced the first innovation from its recently created R&D department, with the development of a new twin-wire system for its WOC processes, which significantly reduces production time.
The company's expertise in WOC service provides heavy-duty protection against corrosion and wear for process and pipeline equipment, and offers significant savings when compared to manufacturing from solid corrosion resistant or wear resistant alloys. It is specified in many industries to enhance the life of new components, and refurbish and extend the life of worn parts.
Arc Energy's, QA and welding engineering manager Peter Minett says that reducing production time is an obvious advantage to customers; and the biggest influence on cladding production time is the rate at which the material can be deposited.
The twin-wire system introduces a second consumable wire into the welding process, immediately doubling the deposition rate.
Putting quantities and deposition rates into perspective, Peter explains that a 2.8m-long vessel with a diameter of 950mm being clad with a 4mm thickness of material, will take almost 300kg of alloy. The conventional GTAW process would deposit the alloy at a rate of just over one kilo per hour.
The new twin-wire system almost doubles this deposition rate, providing obvious savings in production time.
