Product Description

LT·H08MnA 2.5/3.2/4.0/5.0mm Submerged Arc Welding Wire

LT·H08MnA Conform to Standard :GB/T 5293 H08MnA

AWS Em12

ISO 14171-B-SU22

Specification:It is a kind of medium manganese-low silicon type welding wire,matches with medium-manganese and medium-silicon welding flux,Insensitive to rust on the base metal, It has excellent bead molding and slag detach ability.The wire can be applied single or dual feeding with AC/DC.

Purpose:Using with sintered flux LT•SJ101 , it can be applied both for high-speed welding steel plate of tensile strength 420N/mm2 and filling welding

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.
