Arcaloy MC309L is a composite metal cored stainless steel wire which has a stainless steel sheath. Arcaloy MC 309L is designed for welding type 309 wrought or for welding type 304 to mild carbon steel. It is also recommended for cladding 304 when welded to carbon steel. ~As a small diameter cored wire, it can be used for welding thin gauge 304L where increased corrosion resistance over Arcaloy MC308L is needed. It is also used for dissimilar welding between the 300 and 400 series stainless steels and mild and low alloys steels. Its higher deposition rate and less penetration compared to solid wire make it very suitable for making butt, fillet and lap welds on gauge material. ~Higher speeds are also possible compared to solid wire. The low spatter and slag-free welds make this electrode ideal for automatic and robotic welding. The pushing technique can be used to further minimize the penetration and oxide film formed on the surface of the weld. ~Typical applications include automobile catalytic converters, manifolds, mufflers, exhaust systems. ~For welding in the spray mode of metal transfer, the shielding gas should be argon with 1 or 2% oxygen or carbon dioxide. Pulse welding can also be used to further minimize penetration in thin gauge steels. This metal cored wire can also be used in submerged arc welding in combination with 10.93 Flux.
The Shield-Bright series of gas-shielded stainless cored wires are specially designed to produce superior operability for all-position welding applications. Regardless of position, the weld deposit will be flat, which is a quality provided by the faster freezing slag. With a rutile based slag system, Shield-Bright gas-shielded flux-cored wires always operate in the spray transfer mode and can be used at high currents with high deposition rates using mixed or CO2 shielding gas. A full range of grades makes product selection simple.
Shield-Bright wires have easy slag release, even in V butt joints. When not completely self-releasing, the slag can be removed with minimum effort. The spatter levels are nearly non-existent, allowing for additional savings in post-weld cleaning.
ESAB's Arcaloy stainless steel metal-cored wires are small diameter stainless steel composite electrodes designed primarily for the welding of thin gauge materials. These wires have all the typical characteristics of a metal-cored wire: higher deposition rate and a rounder penetration profile than a solid wire. As a result, these wires are best used to make small butt, fillet, and lap type welds on gauge material at increased travel speeds compared to solid wire, which is ideal for automated or robotic welding applications.
