Applications: 

It is suitable for the welding of Rm 430MPa level carbon steel structure, such as SA-36/Gr.D, and so on.

 Characteristic: 

THM-43 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.
