For equal leg fillet welds (cordões de lados iguais), the leg lengths of the largest right isosceles triangle which can be inscribed within the fillet weld cross section. For unequal leg fillet welds, the leg lengths of the largest right triangle that can be inscribed within the fillet weld cross section.

eléctrodo nu
(bare electrode)
A filler metal electrode consisting of a single metal or alloy in the form of a wire, strip, or bar that has had no coating or covering applied to it other than that which was incidental to its manufacture or preservation.

eléctrodo revestido
(coated electrode, covered electrode)
A composite filler metal electrode consisting of a core (alma) of a bare electrode or metal cored electrode (eléctrodo com alma) to which a covering sufficient to provide a slag layer on the weld metal has been applied. The covering may contain materials providing such functions as shielding from the atmosphere, deoxidation, and arc stabilization and can serve as a source of metallic additions to the weld. Flux is applied externally by dipping, spraying, painting, or similar methods.

em bruto
