ABSTRACT
Welding is a complex industrial process that often requires several trials before it can be done right. The welding processes are carried out by skilled workers, but in the past few years automated machines and robots are introduced in shipyards. To obtain the expected productivity through mechanization, high precision of parts to be assembled must be kept. Therefore in the shipbuilding industry dimensional predictability is important. In order to produce a highquality product, the accuracy control should be kept through the whole assembly line. The concept of accuracy control should be incorporated in the structural design, so that the designer can produce a better design accounting for the geometric inaccuracy.
