Tack welding is a quick pre-welding process of applying small dot-like beads throughout the joint’s length. The welding of the longitudinal stiffeners to the plating using intermittent fillet welds could be carried out in a staggered or chain Failure mechanism of stiffened plates The decks of ships, offshore topside structures, box girder bridges and other plated structures are constructed using a series of cross-stiffened panels, as shown in Fig. Most, but not all fillet welds are of equal legs. You can create intermittent fillet welds by using pitch, length, and number of bead. An intermittent fillet weld is a type of weld that consists of a series of individual welds made at intervals along the length of a joint. Image A: The weld size is to the left of the vertical leg (3/8 of an inch). Groove weld reinforcement shall comply with Tables 5. The intermittent welding symbol should not be used when precise location and length of weld is required, rather it should be interpreted as: Weld size - size specified is the minumum leg size permitted.
