Semi-automatic carbon dioxide welding is increasingly used in assembly and welding lines. It is highly productive and of high quality at a relatively low cost of work on the organization of lines. The hygienic assessment of conveyor-type welding lines allows to give a qualitative and quantitative characteristic of the main factors that form the working environment, to study the principles of organization and working conditions of the service personnel in order to develop appropriate measures to ensure their optimization.

The results of physiological studies in welders and line assemblers indicate small but significant changes in the functions of the visual analyzer, cardiovascular and neuromuscular systems. Manual re-edging of products and long-term maintenance of a forced posture increases the severity of the work of welders up to category III, fitters - up to category II-III.

The design, construction and operation of assembly and welding conveyor lines should be carried out with the obligatory consideration of hygienic, sanitary-technical and ergonomic requirements for the state of the air environment, the level of physical factors accompanying the process, and for the organization of the operator's workplace. The results of studying the morbidity of welders and assemblers of conveyor lines confirm the need to develop special means for protecting the organs of eyes and respiration.
