Shanghai Metal Corporation has been doing business for welding wire for decades. Its products features good quality and durability. 

Gas-shielded Solid
Introduction: JQ.MG80-G is a kind of high strength gas-shielded welding wire. The mixed gas Ar+20% CO2 can be used as shielding gas. It has soft arc, stable burning and fewer spatters. The bead has higher impact toughness.
 
Uses: Suitable for welding high strength structures with tensile strength of 790MPa. It can be used for welding some key structures, such as pressure vessels, construction machinery, hoisting machinery, ships, mining machinery, etc.

Instructions:
1. The impurity content in the shielding gas should be strictly controlled to guarantee the purity of gas.
2. When welding, the gas flow rate is generally 20～25L/min.
3. The extension elongation should be 15～25mm.

Argon-arc Welding Wire

JQ.TG50   

According with GB ER50-6

Corresponding with AWS  ER70S-6

Uses: Used for all-position manual tungsten argon arc backing weld and arc welding on pipelines, and both can produce satisfactory welded joints. Able to be used for welding carbon steel and some low-alloy steel.

JQ.H10MnSi

GB：H10MnSi

AWS：EM13K

Current：Used together with fused flux 350 or sintered flux 101. Used for both high speed welding and filling welding on 50kg class base metals. Mostly used for welding boilers, pressure vessels, bridges, ships, etc.

Main Applications： 

JQ.H10MnSi

According with GB H10MnSi

Corresponding with AWS  EM13K 

Introduction: It 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 and high welding efficiency.

Uses: Used together with fused flux 350 or sintered flux 101. Used for both high speed welding and filling welding on 50kg class base metals. Mostly used for welding boilers, pressure vessels, bridges, ships, etc..
