CLASSIFICATIONS: E111T1-K3C/K3M per AWS A5.29, ASME SFA 5.29

APPROVALS: ABS E111T1-K3C (111-K3C only), E111T1-K3MJ (111-K3M only)

Select 111-K3C and Select 111-K3M are designed for single and multiple pass welding, in all positions, of specific high strength, low alloy steels wherein a minimum tensile strength of 110,000 psi is important.

APPLICATIONS: Both premium electrodes are ideal choices for matching the tensile strength of certain base metals such as ASTM A514 and HY-100. These steels are used in various fabrications such as cranes, trailers and boom assemblies.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: Select 111-K3C (100% CO2), Select 111-K3M (75-80% Ar/balance CO2), 35-50 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

    		• Produces high strength weldments with good low temperature CVN impact properties.
    		• Smooth, stable arc with low spatter emission.
    		• Uniform weld beads with excellent tie-in.
