Sandvik has introduced a new welding strip titled Sandvik 24.29.5.Lcu, for overlay welding. Suitable for oil and gas applications, such as pipe and tube, heat exchangers as well as chemical plant and vessel repair. 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%. 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 that has good resistance to corrosion from phosphoric and sulphuric acid and sea water.
