The gas-delivery system was purged for at least two minutes between subsequent welds. The welds were carried out on chemi-etched samples, with chemi-etched filler wire and using a twin-spot energy profile, based on the thus far accumulated experience. (W 354) (1)

Gas-delivery system = Sistema de saída de gás

This report evaluates a new high velocity flame-spray system that uses consumable in a wire form. (W 295) (2)

Flame-spray system = Sistema de pulverização de chama

To combat surface melting, further changes were made to the remote heating zone pattern using the deflection system. (W 225) (3)

Deflection system = Sistema de deflexão
