F7A2 – EM13K
Description and Applications
AWF-501 is a aluminum-rutile bonded/agglomerated flux which can be used in high speed, AC or DC welding of low alloy steel where cracking and porosities are a problem. It is suited to single pass, double sided, and fillet welding. It also provides a very smooth weld bead and has good slag detachment. It is somewhat resistant to rust and mill scale on the surface to be welded. Applicable base metals include: Mild Steel and Low Alloy Steel.
Typical applications include: Boilers, Pressure Vessels and Ship Building.
