How to use hot 317 welding rod?
R317 is a low alloy steel welding rod with low sodium hydrogen type. It can be welded in all positions by DC reverse welding, and the welding process is good. The weldment should be preheated to 250~300 DEG C before welding and should be treated at 700~740 DEG C after welding.

The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.
