Tru-Core® FC 70T Welding Wire is a flux-cored, gas-shielded electrode designed for single- and multiple-pass welding of carbon steels in the flat position and for horizontal fillets. It is suitable for welding most carbon steels requiring a minimum tensile strength of 70,000 psi.
Tru-Core® FC 70T Flux-Cored Welding Wire
Tru-Core® FC 70T is the go-to flux-cored, gas-shielded electrode for single- and multiple-pass welding of carbon steels in the flat position and for horizontal fillets. Suitable for welding most carbon steels requiring a minimum tensile strength of 70,000 psi, Tru-Core® FC 70T offers consistent results for users of E70T-1C H8 and E70T-9C H8 welding wire. This electrode is designed to operate with 100% carbon dioxide shielding gas, and its rutile-based slag system promotes a smooth arc transfer and extremely easy slag removal for a user-friendly welding experience every time it’s used.
Featuring a flat bead geometry, Tru-Core® FC 70T is a great choice for deep groove welds. It's low spatter and smooth feedability characteristics offer welders a dependable result that’s simple to achieve. Moreover, it provides superior mechanical properties, stable current transfer at the contact tip, and a smooth arc transfer, ensuring steady and highly efficient welding operations.
This electrode is manufactured at our Stillwater, Oklahoma, plant, an ISO 9001:2015 facility, using patented forming, feeding, and drawing equipment, allowing for consistent strip-to-core ratio and precise thermal treatment that controls the type, amount, and uniformity of surface oxides on the wire. Tru-Core® FC 70T also boasts consistent diffusible hydrogen levels and a consistent distribution of core ingredients, which are critical factors that add to its performance.
Tru-Core® FC 70T flux-cored welding wire is known for its effective versatility and superior weld quality when working on heavy-duty welding jobs. The construction, manufacturing, and automotive industries can greatly benefit from the stability and control that welders experience with this type of welding wire.
