Product Description

Class: E312-16

AWS: A5.4

Conforms to Certification: AWS A5.4        ASME SFA A5.4

Weld Process: Shielded Manual Metal Arc

Application
E312-16 electrodes were originally designed for the welding of high tensile alloys to high temperature heat-resisting alloys on turbo-jet engines. However, based upon performance, these electrodes have found wide acceptance for the welding of newly developed high yield steels and abrasion resisting steels and dissimilar steels. The weld deposit of E312-16 electrodes, "as welded," has the highest tensile and yield strength of any stainless arc welding electrode commonly used today.

Available Sizes & Recommended Welding Parameters
Diameter	Voltage	Flat	Amperage Vertical & Overhead
3/32	24-28	70-85	65-75
1/8	26-30	85-110	80-90
5/32	28-32	110-140	100-120
3/16	28-32	120-160	110-130

NOTES:
1.  Electrodes must be baked for 1 hour at 250-300°C before welding.
2.  Do clean up the rusty, oil scale,water and other impurities on welding parts.
3.  Short arc operation is required when welding  and the small current is better.
