New overlay strip can halve welding time
Sandvik has developed a new welding strip for overlay welding which can significantly improves welding productivity, reducing the welding time by half.
Suitable for oil and gas applications such as pipe and tube, heat exchangers and chemical plant and vessel repair, Sandvik 24.29.5.LCu is quick and easy to use and provides an ideal overlay.
Traditionally, 904L overlay welding is carried out with a double pass weld. Use of this new Sandvik material allows the required grade to be reached with one weld, cutting previous operational time by around half, while achieving the required material grade.
The new welding strip is available in coils, 30, 60 or 90mm wide by 0.5mm thick.
Designed for use with corrosion-resistant high-alloy austenitic stainless steels and nickel alloys, the welding strip gives a weld overlay which has good resistance to corrosion from phosphoric and sulphuric acid and sea water.
"Of course, an additional benefit of the new material is that because the operation is reduced to just one layer, it also reduces the risk of any mishap during the welding operation," said Sandvik's Linus Svensson.
