Orbital TIG head welds return bends in thin tube

A weld head for the welding of return bends to thin walled tube in heating and cooling equipment offers consistent TIG torch rotation, and constant or variable welding current.

Orbimatic (UK), the manufacturer of technology leading Orbital TIG Welding equipment, have introduced the M45 weld head for the welding of return bends to thin walled tube in heating and cooling equipment.

The M45 weld head has been designed to enable the welding of thin walled stainless steel return bends to tubes fitted in to heating and cooling equipment.

The M45 allows this task to be carried out using a precision Orbital Welding Power Supply, such as the Orbimat 165CB range.

This means that not only is the rotation of the torch consistent, but the delivery of the welding current is also kept constant and can be varied around the circumference of the tube.

Allowing the heat input to be reduced as heat builds up in the tube sheet.

The heads are controlled with closed loop servos and parameters are monitored 500 times per second to provide a precise and accurate control of the weld profile.

It can be used for tubes which are flush, receded or protruding from the tube plate and the tungsten can be angled by up to suit the specific application it is being used for.

Tubes from 6mm to 20mm OD can be welded with completely repeatable results.

Because the welding arc is contained in an enclosed chamber which is filled with inert gas the M45 can be used to weld stainless steel, nickel alloys and titanium tubes.
