94 p. : ill. (some col.) ; 30 cm. + 1 computer disc In this paper, the objective of the study is to determine the effective air extraction system and safe protection during welding process for welding bay in institution of higher learning. This thesis begin with a visitation at institution which have air extraction system to study more detail about this system. Some interview with the coordinator is needed to get their experience during handle their laboratory. The next step is design and fabricate the portable air extraction system for the analysis process. Its start with sketching, 3D drawing and fabrication. For the analysis, some distance and angles was taken to get the effective distance and angle of that system during welding process. The sample of the welding also was taken to determine the good distance of hood of the system before its disturbing the structure of the workpiece. So that the student will know the effective distance and angle and safe protection for the welding. specialized Mohd Khairul Jeffridin Daud Project paper (Bachelor of Mechanical Engineering) -- Universiti Malaysia Pahang - 2008 Ventilation Exhaust systems THE0006460(Local) UMP 090828 20251114204419.0 vtls000042900
