Horst Jöbstl (Managing Director Schwing GmbH): “ With the new laser-sealed cored wires from the diamondspark series, Böhler Welding is setting new milestones in welding consumables and support herewith PALFINGER with the continuous development to ensure the global quality benchmark in lifting solutions.”ĭipl.-HTL Ing. Controlled wire cast and helix largely avoids “dog tailing”, giving, well positioned welds.įranz Wirnsperger (Head of Welding Technology and Analyses PALFINGER AG): ![]() The copper coating enhances current transfer between contact tip and wire – and together with arc stabilizers in the filling – promotes good arc ignition and a stable arc. The seamless, copper coated wire design adds sufficient stiffness and glide to overcome friction in liners, welding guns and contact tips. Without increasing hydrogen level in weld metal even after long term exposure, these wires provide the very best low-hydrogen performance available in the market. For the simple reason that there is no open seam running over the wire length, moisture cannot penetrate into the filling.ĭiamondspark tubular seamless cored wires are produced with very low levels of diffusible hydrogen – typically 2-3 ml / 100g weld metal for rutile types and even lower for metal-cored and basic wires and the diamondspark laser-sealed metal-cored wires are even ultra-dry with average initial hydrogen levels well below 2 ml / 100 g weld metal.ĭiamondspark wires maintain this property until the moment of welding, regardless of the duration of storage and time of exposure at the work site. Within the field of flux-cored arc welding, the seamless design offers optimal protection against moisture reabsorption and thereby against hydrogen induced cracking / hydrogen assisted cracking (HIC, HAC, cold cracking). One of the features of diamondspark metal-cored wires is a wide envelope of applicable welding parameters, enabling easy setting and wider use of productive spray arc parameters. In fillet welding, significantly higher travel speed can be applied than with solid wires, with excellent weld quality. Arc stabilizers make favorable spray arc welding start at welding currents where solid wires of the same diameter operate in the short or globular arc mode, with associated superior productivity and virtual absence of spatter. In the downhand position, Böhler Welding metal-cored wires are the fastest way to join steel plate. On top of this basic productivity advantage, diamondspark cored wires make use of the powerful option to very precisely influence welding characteristics with well-designed cored wire formulations.īöhler Welding rutile cored wires with fast freezing slag, for instance, provide deposition rates in positional welding up to three times as high as obtainable with any conventional arc welding process. ![]()
