However, it is possible to obtain full weld ,depth, penetration by altering the normal weld techniques for uncoated steel. If the angle of the electrode is reduced from the normal 70º to 30º , and the weld speed is reduced significantly, normal weld depths can be achieved by moving the electrode back and forth in line with the ,joint,.

welded joint, when fracture ,occurs, at the location of lack of fusion in spite of a relatively low load applied. Fracture will usually run along the weld interface or individual beads, and thus indicate that there really is lack of fusion [7 - 14]. The main cause of the occurrence of lack of fusion ,is insufficient, …

However, the stress concentration effect ,of the welded joint, decreases as the crack grows across the plate width away from the end of the stiffener. To reflect this observation, the M kc values were varied, decreasing from an initial value of about 3.9 (corresponding to M ka at a = 0.1mm) to M kc = 1.0 when the crack had just grown beyond the weld (about 32mm long) in front of the attachment.
