The Tube 2018 trade show in Düsseldorf is a chance for players in the tubing industry to present their latest innovations from manufacturing to on-site assembly.
This show will be the opportunity for Polysoude to present its orbital tube welding solutions, developed thanks to many years of expertise in the TIG process and which meets customers’ needs as closely as possible.
Polysoude has also innovated in the sector of tube weld overlay by developing TIG bi-cathode technology (TIGer) which creates significant productivity gains.
Orbital TIG welding: Quality and yield
Regulations and standards that govern the tube sector are imposing stricter quality on manufacturers. Based on this observation, for several years Polysoude has been developing orbital welding solutions using the TIG process.
This is a stable and reliable process, with or without filler wire, and can be used on all sorts of materials. Combined with a wide variety of Polysoude welding heads and programmable power sources, it thus covers all tube sectors and ensures quality, regularity and repetitiveness in line with manufacturers’ demands.
Among its wide orbital welding range, in recent years Polysoude has developed the MW34 for high-productivity applications without wire filler. Its compact design, its ergonomics and its high operating factor are its key advantages. It is fitted with titanium tube clamp inserts (TCI™), which adapt to tube dimension tolerance variations and meet non-contamination requirements. With an operating range from 6 to 34 mm, the tool is ideal for the aeronautics, bio-chemistry and micro-electronics sectors, as well as pharmaceutical, food and conventional chemistry sectors.
For clean room welding applications, Polysoude can complete the installation with its P4 power source and its remote touchscreen option. The operator can thus select the welding procedure, programme and monitor the welds without leaving the cleanroom, thus minimising the risk of contamination.
Polysoude has also added the TS 8/75-2 welding head to its range. Its advantages are its high duty cycle and its pneumatic clamping system controlled via its ergonomic handle. Its integrated rotating wire feeder is also a significant advantage as the wire does not become twisted and no longer has to endure any variations in speed; this results in productivity and quality gains.
Suitable for all drilling pitches thanks to its adjustable stand-off legs and with a wide range of tooling available, the TS 8/75-2 is the ideal welding head for all types of tubular heat exchangers consisting of tubes with an inner diameter of 10 to 60 mm.
SPX TIGer weld overlay: Constant productivity gains
One concern of pipe manufacturers, which has clearly increased in recent years, is productivity gain. With this in mind and after years of development, Polysoude has developed the TIGer. Technology.
This bi-cathode technology designed especially for cladding allows lower ferrite levels (< 5 %) and deposition rates above6kg/h with a speed of 1000 mm/min, while preserving the quality of conventional TIG. It therefore responds perfectly to the requested productivity gain.
Polysoude aims to continually adjust to market requirements and, based on long-standing experience in weld overlay using endless rotating collector heads (SPX) in TIG Hot Wire welding, Polysoude can now propose its TIGer process for SPX heads and thus provide continual high-yield weld overlay.
