AWS A5.9 ER316L
MIG Welding Wire ER316L
AWS A5.9 ER316L Gas shielded Solid Welding Wire is 18Cr-12Ni-2Mo; it is Stainless steel MIG welding wire. It is all position welding. The weld-ability is good. Feeding wire smoothly will enable stable arc, excellent welding performance and spatter is very low. It has good resistance for acetic acid, sulfuric acid, phosphoric acid and salt corrosion because it contains Molybdenum.

Welding Positions:
Notes:
1. Shield gas: Must ensure not to operate with impurity shield Gas.
Recommendation Rate of mixed gas: Ar+1-3%O2.
2. Operation flow rate of shield gas: 20-25L/min.
3. Electrode extension: 15-25mm
4. The welding should be operated in clean surface without rust, moist, oil contamination and dust.
5. Prevent affected of wind when wind speed reach 1.5m/s to avoid bubbles generated.
The above suggestions are for reference purpose. Evaluate and determine the situation of the scene before starting the wielding process.
