ACCORD WITH: GB /T 5293 F5A2-H08A

EQUIVALENT NORM : AWS A5 . 17F7A2 - EL - 12 / EL - 8

FEATURES :

·GSW.EL- 12 weld seam metal has excellent mechanical properties. Fast melting rate,high efficiency, flux consumption is small.

APPLICATIONS:

·Suitable for welding low-carbon steel and some low alloy steel,such as butt and fillet welding for thin plates and boilers.

INSTRUCTIONS:

a. Before welding,the welding zone must be cleared away impurities,such as oil,rust, moisture,etc.

b.Please keep the flux in 350℃ boiler for one hour and then dry it again, in order to avoid gas porosity.
