[The effect of the working conditions on the development of diseases in cast-iron welders].

It was established that during cast-iron welding unfavourable factors of this production are welding aerosols, thermal and physical loads, radiation of the optical range. Results of detailed medical screening evidence that 80% of cast-iron welders showed pathology of the internal organs. Diseases of the bronchopulmonary apparatus occupy the leading place and are registered in every second cast-iron welder. The incidence rises with increased length of work and age.
