The dimensional measurement and inspection technologies of propellers are applied to each stage of casting, matching grinding and inspection in major processes of propeller manufacturing and play a critical role to decide quality level of final products. In thins study, an automation system which is more precise, accurate, rapid and simple to measure fixed pitch propellers greater than 5 m was developed and an optimized measurement process with the automated large volume metrology system, a pitchometer, was founded. The developed system was to automate the whole process from planning, measurement, data processing to generating reports, whereby the work environment for one man was built up and the process was standardized. These have contributed to perform the safe and designed measurement process.

In shipbuilding industry, welding position are usually flat and vertical position at the erection stage. Application of SAW and EGW for these positions makes it possible to achieve enhanced productivity and high quality. But owing to their large size and weight it is difficult to apply these techniques in short and narrow regions. To overcome this problem, our company developed light weight and compact size 4-axis welding carriage which perform 3D weaving. The purpose of this study is to explain the development and application of intelligent welding carriage using 3D weaving pattern that can fill a large amount of welds and thereby making it possible to achieve high quality of welding. This study shows 3D weaving pattern, development of weaving database, and skill of adaptive control response for the variable gap. Also, it shows the results of procedure qualification test for the AH-grade steel when applied to the intelligent welding carriage.
