Orbital-TIG – a great wayto join pipesBy: Juha Lukkari, ESAB Oy, Finland.ESAB supplies a complete range of orbital TIG-equipment – including power sourcesand weld monitoring programmes - for the mechanised welding of pipes.Why mechanisation?Although pipes have been welded using mechanisedsystems since the 1960’s, the TIG-process still accountsfor a considerable amount of manual welding. Yet, thereare many good reasons to explore the use of orbital TIGweldingfor applications ranging from single-run weldingof thin-walled stainless pipes to multi-run welding ofthick-walled pipes, and even narrow-gap welding:• Young welders are difficult to recruit.• Operator ergonomics are improved significantly.• Remote control and video control options.• Increased duty cycle - so higher productivity.• Welding procedures repeatable - resulting in aconsistent weld quality.• Good control over heat input.• Equipment available for use “on site”.Stationary vs. orbitalThere are two main catagories of mechanised weldingsystems:• Stationary: the welding head has a fixed positionwhile the pipe rotates.• Orbital: the pipe has a fixed horizontal or verticalposition while the welding head rotates.Orbital-TIG clamp-on weldersClamp-on pipe welding tools are used in orbital weldingof small and medium-sized pipes, see figures 1 and 2.The tools can also be equipped with a wire feeder. Themaximum pipe diameter that can be handled is around200 mm. Tools bigger than this are impractical andunwieldy. The same type of welding tool can be used toweld pipes within a specific diameter range. The PRB/PRC clamp-on welding tools, for example, cover thediameter ranges 17-49 mm, 33-90 mm and 60-170 mm.Normally, pipe standards are taken into considerationwhile designing welding heads, in order to make theFigure 1. Three PRB welding tools for pipe diametersØ 17-170 mm. They are compact welding heads witha unique pincer action. The head is positioned andsecured around the pipe in seconds.Svetsaren no. 1 • 2005 • 3
