Seamless wires offer extreme resistance to moisture pickup


June 18, 2014 — Addressing common industry concerns with weld cracking, Hobart Brothers Company has introduced new seamless flux-cored and metal-cored wires designed to offer extreme resistance to moisture pickup and minimize this costly defect. The new Hobart Megafil wires also have less than 4 ml of diffusible hydrogen per 100 g of weldment, which further mitigates cracking risks.



Both the flux-cored and metal-cored versions of the Megafil wires feature a copper coating to improve current carrying capabilities and with it, provide excellent weld quality. A proprietary manufacturing process adds to the consistency of the Megafil wires by ensuring a uniform flux filling, while the wires’ uniform shape helps minimize contact tip wear. These properties make the wires a good choice for both semi-automatic and robotic welding applications.
The Megafil wires also offer robust mechanical properties, allowing the welds created with these products to withstand the harshest environments.
