Welding Alloys – Advanced Wear Protection
Welding alloys offers industry-leading flux cored and metal cored wires, plus coated/tubular electrodes for hardfacing, rebuilding, and repair.
These wires consist of hard phases within a matrix, whose structure is determined by the composition of the filler metal.
Products with high boron content deliver the optimal solution for combating a broad range of pure abrasive wear conditions. HARDFACE BN, HARDFACE BNC, and HARDFACE NCWB can achieve high hardness starting from the first layer; however, applying a second layer or repairing an existing hardfacing deposit with these wires is not recommended due to the risk of spalling.
A vast selection of cored wires can be engineered and manufactured simply by adjusting or incorporating specific elements. For instance, by adding an appropriate amount of niobium, our HARDFACE HCNB-O enhances wear performance from the first layer, offsetting the dilution effect on the substrate.
With most of these wires, shrinkage cracks will form in the deposit. These cracks arise from the natural stress relaxation within the deposit. Stress-relief cracking typically does not occur when using cored wires specifically designed for impact resistance.
Pioneers in flux cored and metal cored consumables, Welding Alloys provides specialized hardfacing solutions for build-up, repair, and surface protection. Seamless wires (ROBODUR/ROBOTOOL) and advanced alloys ensure optimal performance in demanding environments.
Self-shielded (-O), gas-shielded (-G), and submerged arc (-S) options available. Expert support for consumable selection worldwide.
Our range of cored welding wires are categorised into product families. Below is a brief overview of our main product families for Hardfacing applications, which will help to guide your selection process:
Our hardfacing consumable experts will support you in choosing the right consumable for your requirements.
