AWS E309LT-1/4
Suitable welding positions
CWB to CSA W48 AWS A 5.22M:2012
Typical applications
Welding of 22%Cr-12%Ni stainless steel and depositing buffer layers for various stainless steels for chemical engineering, textile industries, shipbuilding, and atomic power plant industries.
Characteristics on usage
- 1. E-309LT is a flux-cored wire for use in CO2 or AR+CO2 gas and can produce low carbon 22%Cr-12%Ni all-weld-metal.
- 2. Low spatter generation, easy slag removal, and excellent bead shape and appearance.
- 3. High-efficiency welding is obtained in flat and horizontal fillets welding.
- 4. Welding of dissimilar joints consisting of stainless steel, carbon steel, or low alloy steel.
- 5. It provides better weldability with superior heat resistance and corrosion resistance.
