Frequently asked questions
Common questions about Flux Cored Wires (FCW). For specification-grade enquiries, please request a technical sheet via the documents block above.
What is flux cored wire?
Flux cored wire is a tubular welding wire with a flux core that provides deoxidation, arc stability and slag protection — giving high deposition rates and clean, strong welds.
Are your FCW grades certified?
Yes — the range is BIS-certified and RDSO-approved for Indian Railways on the relevant grades, manufactured under ISO 9001:2015.
What grades are available?
Seven grades across carbon steel, stainless steel and hardfacing, including gas-shielded (e.g. E71T-1C) and self-shielded options.
What is your capacity?
Flux cored wire capacity has been scaled to 3,600 TPA to support the division's rapid growth.
