Welding Alloys has been a global leader in the production of advanced welding consumables for more than 50 years. We formulate new fit-for-purpose welding consumables and produce wires tailored to suit more advanced welding processes, such as laser, arc spraying and additive manufacturing. We provide innovative wear protection solutions for even the most challenging service conditions in a range of industries. Complementary to our welding consumables, we manufacture a range of automated equipment for hardfacing, joining and cladding. We also offer engineered wear solutions, IntegraTM services, in our workshops, or in situ, as well as a wide range of wear plates, pipes and components. Since 1966, the Welding Alloys name has been synonymous with excellence in research and development (R&D), resulting in a steady stream of innovative products and advanced technical solutions and services. Welding Alloys is a participating member of the United Nations Global Compact and supports all principles relating to the environment, labour, human rights, and anti-corruption. Reflecting this, we have developed welding wires that emit less harmful fumes, and we manufacture a range of our wires using processes that produce less harmful waste for the environment. We continue to improve our products and processes in order to reduce the negative impact on both the welder and the environment. Our company welding-alloys.com 1 Back to contents page
welding-alloys.com 2 Laser wire cladding & hardfacing: our offer At the forefront of innovation, Welding Alloys is a pioneer in the development of specialist wires for laser cladding and hardfacing. We understand the demands of laser applications and have engineered our consumables to deliver the performance, durability, and reliability needed. Enhanced availability and efficiency Our wires are readily available in convenient lot sizes, ensuring you have the necessary materials on hand without unnecessary delays. Safer and easier handling Unlike fine powder particles, which pose significant hazards to both people and the environment, wire products are safer and easier to handle. This reduces the extra effort, cost and time typically associated with managing powders. Additionally, wires are less prone to contamination compared to powders, ensuring the purity and quality of materials remain intact. Optimal productivity Cored wires offer 100% material recovery, meaning all the material contributes to the deposition. Wire feedstock systems also require less maintenance, resulting in maximum productivity. Developed for laser cladding Our range of metal cored wires produces clean weld beads with minimal silicate islands, low fume emissions, and very little spatter. The precise chemical composition, combined with low dilution, delivers superior results for cladding applications with excellent bonding. Wide range Our dedicated laser cladding and hardfacing range includes chromium carbide, boron carbide, tungsten carbide, and cobalt based wires, providing solutions for a wide variety of applications. We develop our wires with the user in mind. We invest in research and development and continuously enhance our range to ensure our wires are the best-in-class solution for laser applications.

welding-alloys.com 4 Highly alloyed steels with hard phases Cored wires can be designed and manufactured by adjusting or adding specific alloying elements. These alloying elements improve resistance to abrasion, impact, metal-to-metal friction, corrosion, high temperatures, or a combination of these wear phenomena. These wires consist of hard phases in a matrix, where the structure depends on the metal composition. Optimised cored wires for superior results Products with high levels of carbon and chromium result in chromium cast iron deposits that contain hard primary chromium carbides. These are ideal for abrasion resistance in applications that involve moderate impact. High boron content results in boron carbides and borides, providing the best solution for resisting various types of pure abrasive wear. The laser process results in low dilution with the substrate. This means a high hardness is achieved right from the first layer, whilst still maintaining strong bonding. Consumables: HARDFACE HC-LD HARDFACE BN-LD Applications: Equipment used in agriculture, quarrying and mining, screw flights, for example.

welding-alloys.com 5 Tungsten carbides Cored welding wires filled with advanced tungsten carbides offer exceptional resistance to abrasion. These cast tungsten carbides are added to the wire during the production process. Ideal for laser applications By using laser welding technology, the wire melts in the laser-formed weld pool without damaging the tungsten carbides. As this process has a low heat input and a fast cooling rate, the tungsten carbides are trapped during the solidification, ensuring an even distribution throughout the deposit. In contrast, using a different process with higher energy levels could damage the carbides or cause them to settle at the bottom of the weld pool. Consumable: HARDFACE NICARBW-LD Applications: Equipment used in oil & gas, stabiliser, trenchers, screws, for example.

welding-alloys.com 6 Cobalt based alloys Cobalt based cored wires are mainly alloyed with carbon, chromium and tungsten. However, sometimes they are alloyed with nickel and molybdenum. These alloys are ideal for resisting wear caused by metalto-metal friction and abrasion at high temperatures, as they retain high hardness over time. Chromium provides a protective layer, playing an anti-oxidation role. Chromium, tungsten and molybdenum combined with carbon create hard carbides. Advanced laser wires All of our cobalt based alloy wires, including grades 1, 6, 12, 21, 25 and 188, have been developed for use in laser welding. These materials have a low coefficient of friction and a self-polishing tendency, making them highly resistant to scratching while maintaining excellent surface quality. Laser cladding is a well-suited process for applying these high-performance alloys, as it allows for a precise deposition of the exact amount of material needed to the specified working area. Consumables: STELLOY 25-LD STELLOY 21-LD STELLOY 6-LD STELLOY 1-LD STELLOY 188-LD Applications: Industrial valves and seats, forging dies, hot shearing blades, for example.
