Welcome to Shandong Tengyi Metal Materials Co., Ltd.
EL12/EL8(S1)
Application: Used for welding carbon steels(Q235,Q195 etc.)and alloy steels with a low strength grade e.g.09Mn2,16MnCu etc.
Characteristics: YHO8A is copper-plated,low-carbon and low-manganese welding wire and applied to the union melt welding with welding flux HJ431.The weld metal has excellent mechanical properties,insensitive to the rust on base metal with a good welding process.The welding slag is easy to fall off with a stable arc combustion.Applicable to the single,double polar welding,AC,DC welding.
