A test in which the weld face is on the convex surface of a specified bend radius.

Weld reinforcement on the side of the joint from which welding was done.

The metal or alloy to be added in making a welded, brazed, or soldered joint.

A weld of approximately triangular cross section joining two surfaces approximately at right angles to each other in a lap joint, T-joint, or corner joint.

The distance from the joint root to the toe of the fillet weld.

For equal leg fillet welds, the leg lengths of the largest isosceles right triangle that 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.

A thermal spraying process in which an oxyfuel gas flame is the source of heat for melting the surfacing material. Compressed gas may or may not be used for atomizing and propelling the surfacing material to the substrate.

The welding position used to weld from the upper side of the joint at a point where the weld axis is approximately horizontal, and the weld face lies in an approximately horizontal plane.

The melting together of filler metal and base metal, or of base metal only, to produce a weld.

The area of base metal melted as determined on the cross section of a weld.
