Guide to AWS A5.4: Stainless steel electrodes för SMAW

Covered electrode

for manual metal-arc

welding.

Suffix

-15

E 308 -17

Indicates

Compositional type.

C oating type and usability characteristics

For use with DC+only. Usually basic coating. All positions.

-16

For use with DC+and AC. Rutile coating. All positions.

-17

As for -16, but higher sili ca content in coating gives following:

• More of a spray arc and finer rippled bead surface in H-V fillets. • Slower freezing slag permits

improved handling with a drag technique. • Mitre to slight concave H-V fillets • When making vertical-up fillets the slower freezing slag requires slight weave to produce flat profile.

-25

Same coating and type as for -15 but with a mild steel core wire. Flat and horizontal positions only.

-26

Same coating and type as for -16 but with a mild steel core wire. Flat and horizontal positions only.
