Abstract
Welders in shipbuilding yards often do their job with squatting postures owing to the complexity and limited space of ship block. Especially, welding conducted in the head of the ship block, semi-block, and block assembly depends on welders due to low rate of automatic welding. Because of this, welders are always exposed to the risk of musculoskeletal disorders.

Simulation can minimize waste of time and money according to improved working environment and changed progress of work. Therefore, to prevent these diseases, the author evaluated welders’ postures with digital simulation. And the author not only improve welders’ working environment in the virtual space but also assessed the result with simulation. RULA assessment technique was utilized to analyze welders’ postures.

This study has modeled modeling of simulation using the concept of PPR which is composed Product, Process and Resource. And the researcher compared existing assessment techniques with current assessment techniques of human engineering to examine accuracy of digital simulation. Because PPR was saved and managed by the manufacturing hub, Product and Process were modified easily besides various data were easy to manage.

Additionally, graphs showing major physical movement of welders were presented in this study
these graphs allow us to objectively comprehend the effect of welders’ posture improvement.
