FCW 309 LT and FCW 309 LTA Gas Shielded Flux Cored Welding Wires

Filler Metal FCW 309 LT and FCW 309 LTA are used for welding similar alloys in wrought and cast form.
These flux cored wire are used extensively for join Types 304, 347, 321 and 316 and duplex stainless steels to mild and low alloy steels.
These cored wires can also provide a buffer layer prior to surfacing for 308L for corrosion resis¬tant overlays and is often used for dissimilar welds because of its tolerance for dilution. They are also used for welding 304 clad sheets and for applying stainless steel sheet linings to carbon steel.
The working temperature should not exceed approximately 400°C (750°F). FCW 309 LT was developed for flat or horizontal welding position (AWS E309T0-1/T0-4) while
FCW 309 LTA was developed for out-of-position welding (AWS E309T1-1/T1-4).
These cored wires were formu¬lated for use with 75% Argon/25% CO2 shielding gas however, straight CO2 may also be used.
The 75/25 mix¬ture will produce a smooth arc with virtually no spatter and slightly higher yield and tensile strengths than CO2.
The slag is self-peeling and mini¬mizes cleanup.
The mechanical properties and deposit analysis will meet AWS 5.22 specifications with either gas.

Available in diam.: 1 - 1.2 mm on spools of 5 and 12.5 kgs.
