Improvement of the Welding Process for Fillet Air Test for the Biggest Taiwan Shipyard

During ship block construction, watertight bulkheads weld of every cabin ships need to undergo stress testing according the tanks’ test plan. Every incomplete bulkhead cannot be sprayed in order protect them after sandblasting; this seriously affects process construction. Therefore, issue study is maintain integrity painting quality and reduce destruction paint, ship-building personnel seek how best complete operation. The aim project improve recent fillet air operations construction stage using TRIZ (theory inventive problem solving), promote ground session ship, plan dock, time spent on dismantling Through TRIZ, proposed lots improvements, some which are: cabins can finish tanks completely, promoted range dock bulkheads’ time. Moreover, because considerate reduction coating, operation good quality. results demonstrate that successfully controls production during reduces working time, promotes full efficiency. This saved more than US$1 million outsourcing fee.
