Webb25 juli 2024 · This is called welding overlap. Overlap welding is indeed the protrusion of welded metal far beyond the root. The overlap is a projection that develops further than the weld toe. While overlap is much more of a welding gap, it is still regarded as a problem. Usually, overlap happens in the butt as well as fillet welds. Webb19 jan. 2024 · The theoretical throat is the perpendicular distance of the weld from the hypotenuse of the largest right triangle that can be inscribed within the fillet weld cross-section (i.e., a line that connects the toe on each side of the root) to the root. The actual throat is the distance from the root of a fillet weld to the center of its face. WebbOverlap – This discontinuity is defined as the protrusion of weld metal beyond the weld toe or weld root. This condition can occur in fillet welds and butt joints and can produce notches at the toe of the weld that are undesirable due to their resultant stress concentration under load.
