AWS A5.4: E309-16 & 309L-16

AWS A5.4: E309-16 & 309L-16

A lower carbon version of the 309(H) Sterling AP. Low carbon content makes it excellent for applications where reduced susceptibility to sensitization during high temperature service is necessary. Outstanding for dissimilar metal welding such as weld overlay or for welding type 309 stainless steel to mild or low alloy steels. It has a smooth running arc that results in a uniform weld bead that is flat to slightly convex.

STORAGE

TYPE OF CURRENT

RECOMMENDED WELDING PROCEDURES

electrodes have a high degree of moisture resistance; however, for critical applications, the
electrodes should be held at 215°F - 300°F after opening.

ARC LENGTH: Short (less than 1/2 the diameter of the electrode)
FLAT & HORIZONTAL: Angle electrode 10-15° from 90°
VERTICAL-UP: Use weaving techniques or inverted V. Reduced amperage compared to flat position setting
VERTICAL-DOWN: Not recommended

OVERHEAD: Use slight weaving motion within the puddle

Direct Current Electrode Positive (DCEP) or AC

TYPICAL MECHANICAL PROPERTIES* (As Welded)

• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending on the type and thickness of steel being welded.
