New welding overlay reduces welding time by half
Sandvik is introducing a unique, new welding strip, Sandvik 24.29.5.LCu for overlay welding, which significantly improves welding productivity, reducing the welding time by half.
Suitable for oil and gas applications, such as pipe and tube, heat exchangers as well as chemical plant and vessel repair, the new overlay material is both quick and easy to use and provides an ideal overlay.
Traditionally, 904L overlay welding is carried out with a double pass weld. Use of the new Sandvik material allows the required grade to be reached with one weld, cutting down on previous operational time by around 100%, while achieving the required material grade.
“Not only do customers save on the operational time taken to complete the weld, but they also save on material usage,” explained Linus Svensson of Sandvik. “In addition, a standard flux can be used for the weld, rather than a more expensive, special flux.”
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.
Sandvik is the largest producer of stainless steel welding strip in the world and its ongoing research and development programme capability ensures the introduction of new, time saving, materials, consumables and techniques for welding.
“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.
“Whether the requirement is for overlay welding to repair a vessel or any other form of welding, our specialists can assist with leading-edge solutions from the company’s extensive expertise.”
