welding-alloys.com 7 Welding consumables Welding Alloys manufactures a range of advanced welding wires designed for railway repair and maintenance applications. Our consumables are developed to withstand the wear and mechanical stresses experienced by rails and track components, including fretting, abrasion and heavy loads. Rail repairs are often carried out during short night-time maintenance windows, where productivity, reliability and repeatable weld quality are essential. Our consumables are manufactured under controlled conditions, with careful inspection and chemical composition control to ensure consistent weldability and performance. Our range helps maintenance teams restore rail profiles, rebuild worn components and improve wear resistance, supporting longer service life in railway environments. Low-alloy steel consumables Used to rebuild rail profiles and restore geometry, with mechanical properties similar to the original material. Suitable only for low- & medium-alloy steels. Austenitic chromium-manganese consumables Designed to work harden under service loads, improving hardness and wear resistance during use. These deposits offer good dilution tolerance and crack resistance. Austenitic manganese steel consumables Used where a high work-hardening capability is required. These materials must be welded using low heat input and controlled interpass temperatures to avoid embrittlement.
