The ability to complete a weld from the inside can very often provide the solution to a seemingly insurmountable problem. This can be achieved in a variety of ways using modified standard OD weld heads or dedicated internal bore welding (IBW) heads. Applications typically require torch assemblies that are tailored to suit the reach and diameter necessary to access the weld joint. Some applications such as heat exchangers with back face IBW welds have been around around for a number of years. However, the equipment and expertise required to successfully apply the process in this way can be difficult to source. In recent years we have provided specialised equipment and application engineering for a number of IBW projects for the aerospace, power generation and nuclear industries. Outline drawing showing an Orbitec IBW weld head for a back face tube to tubesheet application (photo shows the torch end at the joint prior to fitting the tube for welding).

Refrigerating Cooling units are available for specific high duty applications. Please note that due to the specialised nature of such requirements the specification, model and pricing information is available on application. Please contact Orbitec for more information.

Turn table system based on the OSW 115 weld head suitable for welding small components. The package is highly customisable, for butt and fillet joints with and without wire and development welding.

Simple illuminated control panel, with digital display. Power (On Off) and Rotation direction (CW CCW) push button switches. Linear single speed control knob, with center, push button start, stop or jog functions. Gas ID purge through the center shaft. High frequency interference protection. Simple push knob to adjust table angle.

The OSK4TK weld head is a combination of the OSK65W enclosed water cooled weld head and the 4TK kit; comprising electrode holder, nose ring and pneumatic mandrel actuating assembly. This method of producing autogenous tube to tubesheet joints provides a high quality, very clean weld and is particularly suited to Titanium applications because the entire weld circumference is contained within a fully inert environment during welding. This head can be used for tube diameters from 15.0mm to 50.0mm ID, a mandrel assembly is required to complete the package.

Light weight compact power source with 180 ampere output for both manual, and orbital TIG welding with all Orbitec controllers.
