The orbital weld heads HX for compact cooling systems sets new standards!
“HX” stands for heat exchanger and for the welding of pre-mounted elbows in tight pipe bundles of heat exchangers into a pipe coil. At present, there is no other solution as effective as this one in the world!
Due to their compact size, all fully closed or open orbital weld heads commonly available on the market are not suitable for being positioned between the individual pipes of finned heat exchangers.
The HX scores points in the areas of economy and efficiency when compared to conventional weld heads: The pipe outlets of a heat exchanger can be fully fitted with elbows before joining and then welded in any order. For conventional orbital weld heads, the principle of fit elbow, weld, fit elbow, weld etc. applies, always starting from the center of the pipe sheet and working outward. If quality testing reveals a faulty weld later on, all elbows must be disconnected and new ones must be welded on in the worst case scenario (fault in the middle of the bundle) due to the accessibility factor. With the HX head, only the affected elbow would have to be replaced. This design-based advantage also makes the Orbitalum system the ideal tool for unbeatably cost-effective repairs.
In contrast to open weld heads with a cumbersome hose assembly, all connections for power, gas and cooling water are permanently integrated in the HX.
All orbital welding power sources from Orbitalum automatically detect the head and its properties so that the operator only has to call up his or her specified jointing program and start the joining process before beginning to weld.
Traditionally, complex heat exchangers for cooling systems were made of copper and soldered with the pipe elbows. The high price of copper prompted manufacturers to switch over to stainless steel for production. Stainless steel can only be joined economically, reliably and in high quality with tungsten inert gas (TIG) welding in conjunction with mechanized orbital welding.
· Highly durable thanks to liquid-cooled earth plate and rotor housing
· Horizontal, vertical and tilted welding positions are possible
· Very robust and ergonomic design
· Fast and easy mounting at the tube
· Self-retaining weld head thanks to the patented fixation mechanism via pistons which saves up to 80% of the preparation time
· Pneumatic clamping system for easy mounting on the pipe elbow
· External stop for adjusting the electrode position
