  • Automation is also important to replace the skilled workers. Welding is one of the most important jobs in shipyards, and the ratio of the mechanized welding in Japanese shipyards is 42% in average, and 64% in the most advanced shipyard (Miyazaki 2008). Further development of mechanized welding calls for a breakthrough. Miyazaki (2008) showed some challenges such as mechanized welding inside the double hull structure in the assembly stage, and mechanized butt welding of longitudinals inside the double hull structure in the erection stage.

  • Steels are alloys of iron with generally less than 1% carbon plus a wide range of other elements. Some of these elements are added deliberately to impart special properties and others are impurities not completely removed (sometimes deliberately) during the steel making process. Elements may be present in solid solution or combined as intermetallic compounds with iron, carbon or other elements. Some elements, namely carbon, nitrogen, boron and hydrogen, form interstitial solutions with iron whereas others such as manganese and silicon form substitutional solutions. Beyond......
