Orbiweld Orbital Fusion Weld Heads

Orbiweld OW76s Orbital Weld Head

Orbitalum enclosed orbital fusion weld heads range in size from .118in-6.69in (3mm-170mm). These fluid cooled orbital fusion weld heads can TIG weld thin-walled stainless steel tubes and micro-fittings, as well as unalloyed and low-alloyed steels, and titanium.

The Orbiweld series is characterized by very high thermal resistance. It is therefore particularly suitable for applications in the chemical, pharmaceutical, food and beverage industry, where ever greater demands are made on the closed weld heads by ever greater tube diameters and wall thicknesses. Coolant channels running through the entire weld head body ensure an excellent heat dissipation that enable the Orbiweld weld heads to work continuously, even at high welding currents and intensive load.

The closed design of the Orbiweld series with the gas management system of the head ensure a permanent infiltration of the GTAW weld seam during welding with inert gas, guaranteeing seams that have very little heat affected zone (HAZ).
