Submerged Arc Welding Wire EL12

The products easily removable residue, good seam forming and highly efficient deposiyion.Wire meltingdoes not lead to splash or strong flasing.The sem surface is smooth and welding quality is guaranteed. They facilitate mechanical and automatic welding process. With a wide range of welding parameters, the wires can be used in open fields with strong wind and applied to automobiles, ships, bridges and chemical engineering.

 

Main Applications:

It is suitable to weld 450Mpa-500Mpa grade structures ,such as boilers, ships, bridges, pressure vessels, as well as LPG cylinders, Before welding, the base metal must clear away impurities and fht flux must be baked in a temperature of 300°c-350°c for 1-2 hours.
