SUREWELD
SW612 (AWS
E6012) -
This is a multiple purpose rutile electrode that is
useful for poor fitup welding. It deposits convex weld beads that have great
resistance to cracking.
It withstands the high amperage of production welding without coating breakdown.
The weld deposit has excellent mechanical
properties for the classification. The SW612 electrode
is used to weld truck bodies, trailers, tanks, farm machinery and auto parts.
Typical mechanical properties are:
Yield Point - 62,300 psi
Tensile Strength - 69,400 psi
Elongation (2" Gauge) - 21%
Reduction of Area - 54%
The typical chemical composition of
the weld metal is: Carbon
0.05% Phosphorus
0.008% Manganese
0.31% Sulfur
0.016% Silicon
0.12% DEPOSITION
