Paper Title
Ergonomic Analysis Of Welding Operator Postures
Abstract
Discomfort and pain are common in human-work activities and workers working in the industrial sector are easier
to be exposed to the risk injuries. Occupational risk factors are the biggest entity causing health problems. Exposure to
occupational hazards can adversely affect the human body, in turn reduce worker productivity and product/work quality and
increase musculoskeletal problems. Observing the group of operators (welding) working throughout the day in the industry,
which in turn helps in identifying the discomfort/pain experienced by the workers. The discomfort level of the workers can
be evaluated by designing a detailed questionnaire and checklist to be present to the respondent. Ergonomic assessment tools
like RULA (Rapid Upper Limb Assessment), REBA (Rapid Entire Body Assessment), OWAS (Ovaco Working Postural
Analysis System) are used to assess the working postures and to analyze the discomfort frequency. Postures causing
WMSD’s (Work-Related Musculoskeletal Disorders) are identified and recommending the guidelines to improve posture
actions and to reduce the threat of WMSD’s.
