Abstract: This study analyzed and developed a model for
monk’s food bowl production on occupational health safety and
environment at work for the encouragement of Rattanakosin local
wisdom at Banbart Community. The process of blowpipe welding
was necessary to produce the bowl which was very dangerous or
93.59% risk. After the employment of new sitting posture, the work
risk was lower 48.41% or moderate risk. When considering in details,
it was found that: 1) the traditional sitting posture could create work
risk at 88.89% while the new sitting posture could create the work
risk at 58.86%. 2) About the environmental pollution, with the
traditional sitting posture, workers exposed to the polluted fume from
welding at 61.11% while with the new sitting posture workers
exposed to the polluted fume from welding at 40.47%. 3) On
accidental risk, with the traditional sitting posture, workers exposed
to the accident from welding at 94.44% while with the new sitting
posture workers exposed to the accident from welding at 62.54%.
Abstract: This study is about the orbital TIG welding robot system which travels on the guide rail installed on the pipe, and welds and tracks the pipe seam using the LVS (Laser Vision Sensor) joint profile data. The orbital welding robot system consists of the robot, welder, controller, and LVS. Moreover we can define the relationship between welding travel speed and wire feed speed, and we can make the linear equation using the maximum and minimum amount of weld metal. Using the linear equation we can determine the welding travel speed and the wire feed speed accurately corresponding to the area of weld captured by LVS. We applied this orbital TIG welding robot system to the stainless steel or duplex pipe on DSME (Daewoo Shipbuilding and Marine Engineering Co. Ltd.,) shipyard and the result of radiographic test is almost perfect. (Defect rate: 0.033%).
