THQ-60C (ER90S-G)

AWS A5.18 ER90S-G
GB/T 39281 M21 ZCT

Applications: 

It can be used in the welding of carbon steel and low alloy steel in the corresponding strength grade, which can be used in construction machinery, coal mining machinery etc.

 Characteristics: 

Wire of THQ-60C is Rm 600MPa level carbon steel wire with shield gas of M21 only. The welding spatter is small, and it has beautiful shape, high cladding efficiency. It can be used for all position.

 Attention:

1. The rust, oil, water and other impurities of the weld area must be removed before welding.

2. The mechanical properties of all weld metal be decided by heat input, normally the small heat input will better than larger one.
