Applications: 

It is suitable for the welding of Rm 490MPa level carbon steel and low alloy steel structure, such as Gr.50, and so on.

Characteristic: 

THM-12K is copper coated solid wire, and it can be used in automatic submerged arc welding with welding flux. The weld metal has excellent mechanical properties.

 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.
