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.
