35CA12982V - ESAB Shield-Bright 309L .045" Stainless Flux Core Wire 33lb

Technical Overview

The ESAB Shield-Bright 309L is a premium .045-inch diameter gas-shielded flux-cored stainless steel wire designed for high-performance fabrication. Engineered as a rutile cored wire, it meets AWS A5.22 classifications E309T1-1, E309T1-4, E309LT1-1, and E309LT1-4. This versatility allows it to operate effectively with either 100% CO2 or a mixture of 75% Argon and 25% CO2, providing flexibility in shop environments where gas availability may vary. The wire is specifically formulated for the all-positional welding of stainless steels to carbon or low alloy steels, as well as for applying buffer layers on carbon steels prior to filling with 308L.

One of the standout technical features of the Shield-Bright 309L is its operability. It delivers a smooth, stable arc with minimal spatter, which significantly reduces post-weld cleaning time. The slag system is designed to be self-releasing in most conditions, revealing a bright, clean bead profile. Unlike solid wires that can be difficult to control out-of-position, this flux-cored option supports vertical-up welding with ease, maintaining a flat bead contour. The product is supplied in a 33 lb (15 kg) precision-wound spool, packaged in ESAB's hermetically sealed Vac-Pac to prevent moisture absorption and ensure fresh performance right out of the box.

Applications and Specifications

This wire is widely utilized in industries requiring the joining of dissimilar metals, such as petrochemical processing, power generation, and general industrial fabrication. It is particularly effective for welding type 309 and 309L stainless steels, as well as for overlaying carbon steel to provide corrosion resistance. The low carbon content (indicated by the 'L' designation) helps prevent carbide precipitation, maintaining the corrosion resistance of the weldment. With a diameter of .045 inches, it offers a balance between deposition rate and heat input control, suitable for medium to heavy gauge materials.
