The SWX 160 submerged arc welding flux from Hobart offers high impact toughness and helps reduce the risk of temper embrittlement in high-temperature applications.

MEGAFIL wires from Hobart offer extreme resistance to moisture pickup to minimize the potential for costly weld cracking.

Hobart Brothers Company (Troy, OH) has specially formulated its SWX 160 submerged arc welding flux to improve weld quality on chrome-moly, creep-resistant steels. This neutral, agglomerated, fluoride-basic flux provides a low-residual content weld deposit to help reduce the risk of temper embrittlement in high-temperature applications, making it well-suited for power generation, petrochemical refinery and pressure vessel applications. It is also usable in step-cooling applications and for submerged arc welding a wide variety of HSLA steels. The SWX 160 flux helps meet X-factor requirements, along with providing excellent impact toughness to further ensure weld performance in high-strength applications. Additionally, it produces an easily-detached slag to help minimize post-weld cleaning. The SWX 160 flux comes in durable 50 lb Excess Air Evacuation (EAE) packaging that prevents moisture pickup to help reduce the potential for hydrogen-induced cracking.

Addressing common industry concerns with weld cracking, Hobart has introduced new seamless flux-cored and metal-cored wires designed to offer extreme resistance to moisture pickup and minimize this costly defect. Their new 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. The wires are designed specifically for use in offshore platform and bridge construction, shipbuilding, and steel and pressure vessel construction, as well as pipe, tube and heavy equipment manufacturing.
