AWS A5.9 ER316
Welding Wire ER316
Gas-shielded Solid Welding Wire AWS A5.9 ER316, H0Cr19Ni12Mo2 is ultra-low carbon 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.
MIG welding wire AWS A5.9 ER316
Application
AWS A5.9 ER316 is widely used in petrochemical, chemical fertilizer equipment such as 06Cr17Ni12Mo2 (SUS 316L) and other materials of welding.

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.
