OVERVIEW

Premium Flux for Critical Welding Projects

When your project demands the absolute highest quality welds, Hobart SWX 150 Sub Arc Flux is the professional's choice. This 50lb bag of high-performance flux is formulated to tackle the toughest jobs in the industry, from building offshore wind towers to fabricating massive pressure vessels. If you are welding thick steel sections that require exceptional strength and resistance to cracking in freezing temperatures, this is the flux you need.

The SWX 150 is known for its reliability in "can't-fail" environments. It provides a smooth, stable arc and produces welds with excellent bead appearance and easy slag removal, reducing your post-weld cleanup time. Its high basicity means it cleans the weld pool effectively, resulting in incredibly strong and pure weld metal. This makes it perfect for critical infrastructure projects like bridges, nuclear facilities, and cryogenic storage tanks.

Designed for versatility, Hobart SWX 150 works seamlessly with various welding wires to meet specific code requirements. Whether you are performing single-pass or multi-pass welding, this flux helps ensure your welds pass strict X-ray and mechanical testing. Packaged in a durable 50lb bag, it is easy to transport and store in your shop or on the job site. Choose Hobart SWX 150 for consistent, high-quality results in heavy industrial fabrication.

FAQ

Hobart SWX 150 is a high basicity flux with a Boniszewski index of approximately 3.0.

It is designed for Submerged Arc Welding (SAW).

Yes, it provides excellent impact toughness at low temperatures, making it suitable for cryogenic and offshore applications.

It comes in a 50 lb bag.

Yes, its slag detachability and arc stability make it well-suited for narrow gap welding techniques.

SWX 150 is generally considered a neutral flux, meaning it does not significantly add alloying elements to the weld metal.

It should be stored in a dry, controlled environment to prevent moisture pickup, which can affect weld quality.

It is frequently used in offshore, nuclear, pressure vessel, and heavy civil construction industries.
