Orbital / Tube Arc Welding Machine

The machine is widely used for orbital or tube welding processes. The orbital welding process makes use of the Gas Tungsten Arc Welding (GTAW) process as the source of the electric arc that melts the base material and forms the weld.

Working Principle
The orbital or tube welding equipment consists of a power supply and an orbital weld head. In the welding process, tubes or pipes are fixed in place and there is an orbital weld head that rotates an electrode and electric arc around the weld joint to make the required weld. There is a power supply that provides the control specifications, the arc welding current, the power to drive the motor in the weld head and switches the shield gases on or off as and when required. Orbital weld heads are of enclosed type and offer an inner atmosphere cabinet that encloses the weld joint.

Uses & Applications
The orbital or tube welding machine finds application in many fields. Some of its common uses include:

• Metal working
• Aerospace application
• Automotive industry
• Shipbuilding
• Casting
• Machining
• Manufacturing industries
