GTAW + PAW machine ( Model No. : SAF )
Equipment name : GTAW + PAW machine ( Model No. : SAF )
Max. welding capability :4 m length, 450~700 mm diameter, less 6 mm thickness.
Description:
- The Gas Tungsten Arc Welding (GTAW) is an arc welding process that uses a nonconsumable tungsten electrode held in a torch, shielding gas is fed through the to protect the electrode, molten weld pool, and solidifying weld metal from contamination by the atmosphere.
- The Plasma Arc Welding (PAW) is an arc welding process that produces coalescence of metals by heating them with a constricted arc between an electrode and the workpiece. PAW like GTAW uses a nonconsumable electrode. The PAW torch has a nozzle that creates a gas chamber surrounding the electrode .The arc heats the gas fed into the chamber to a temperature where it becomes ionized and conducts electricity. This ionized gas is defined as plasmas.
- GTAW + PAW machine is used in a wide range industrial application. High weld quality, high deposition rates, deep penetration. It is used extensively in pressure vessel fabrication, ship, and barge building, railroad car fabrication, pipe manufacturing.
