CLASSIFICATION
AWS A5.22 E309LT1-1/4 | JIS Z 3323 YF309LC | BS EN 12073 T 23 12 L P C 1
APPLICATIONS AND MATERIALS TO BE WELDED
Used for welding of 22%Cr-12%Ni steel and dissimilar joint such as a stainless steel to carbon steel of low alloy steel. Also for under layer welding on claded side groove claded stainless steel or carbon steel where stainless steel weld metal is overlayed.
WELDING AMPERAGE AC and DC
OTHER DATA
1. 100% CO2 or Ar + 20~25% CO2 mainly used as shielding gas
2. The optimum flow of CO2 for shielding is 20~25 ℓ/min
3. Keep the distance between tip & base metal at 15~25mm
4. For multi layer welding, keep preheat and inter-pass temperature 150°C max.
