4.8.3 Welding sequence and direction of welding passes
The applied method and sequence of welding work are at the shipyard's discretion, however, surveyors are to be familiar with the following practice commonly employed at shipyards during construction of a ship.
4.8.3.1 Butt or seam welding sequence for plates in assembly units.
Any welding sequence convenient for welding work may be selected as not much difference in strength and residual stress will result from either the transverse edge or the longitudinal edge being welded first, as shown below. |
