Task loading of soldering workers in small-scale manufacturing units

Area of Science:

• Occupational Health
• Ergonomics
• Manufacturing Engineering

Background:

• Soldering is a prevalent task in electrical product manufacturing.
• The task load associated with soldering in small manufacturing units remains unquantified.
• Understanding these demands is crucial for worker well-being and productivity.

Purpose of the Study:

• To quantify the task load experienced by soldering workers in small manufacturing units.
• To analyze the influence of age and sex on soldering-related task load.
• To identify key factors contributing to worker strain during soldering.

Main Methods:

• Assessed task load using the National Aeronautics and Space Administration task load index (NASA-TLX) questionnaire.
• Surveyed 102 soldering workers across four small-scale manufacturing units.
• Employed statistical analyses including Mann-Whitney U test, Kruskal-Wallis test, and ordinal regression.

Main Results:

• Soldering workers reported a high prevalence of physical, mental, and temporal demands, along with significant effort.
• Age and specific work characteristics were found to significantly influence overall task loading.
• No significant effect of sex on task load was identified.

Conclusions:

• Soldering tasks in small manufacturing settings impose considerable physical, mental, and temporal demands on workers.
• Interventions focusing on workstation design may alleviate task load and improve working conditions.
• Further research could explore sex-specific differences and long-term health impacts.
