Weeping welds stain the zinc surface at the welded connections on the steel. Caused by entrapped cleaning solutions that penetrate the space between the two pieces, weeping welds can be avoided by providing a 3/32 (2.4mm) or larger gap between the two pieces when welding them. This will allow the zinc to penetrate the gap. The weld must then be made with gaps instead of continuous weld bead, actually making a stronger joint when the process is complete. Weeping welds, as seen in the image to the right, are not the responsibility of the galvanizer and are not cause for rejection.
