AWS EM13K
Submerged arc welding wire
Submerged arc welding wire,AWS EM13K, H10MnSi is a kind of welding wire with appropriate manganese and silicon content. It matches with low-manganese and low-silicon type welding flux. It is not sensitive to the rust on the base metal. It has excellent bead molding, excellent slag detachability. The wire can be applied single or dual feeding with AC/DC.

Notes:
1. Shielding gas: Adopt pure Argon gas. Recommendation flow rate: 9-14L/min (AMP 100-200A), 14-18L/min (AMP 200-300A).
2. Tungsten extension: 3-5mm, Arc length: 1-3mm.
3. Wind speed limited: ≤1.0m/s.
Argon gas shielding on back side of welding part will get better welding result.
4. Mechanic property and metal anti-cracking ability of the welded metal relative by energy pass value on the wire.
5. The welding should be operated in clean surface without rust, moist, oil contamination and dust.The above suggestions are for reference purpose. Evaluate and determine the situation of the scene before starting the wielding process.
