Illustrations for fillet welds using various electrode sizes.

A 1/8" 7018 can potentially produce a 3/16" weld size with one pass and 5/16" with 3 passes.

A 5/32" 7018 can potentially produce a 1/4" weld size with one pass and 3/8" with 3 passes.

A 3/16" 7018 can potentially produce a 5/16" weld size with one pass and 1/2" with 3 passes. NCDOT MATERIALS & TESTS UNIT (STEEL SECTION)
