A cohort mortality study was conducted among welders and nonwelders at three heavy equipment manufacturing facilities from 1950 through 1980. The welders at these facilities were exposed to little or no asbestos and they welded only mild steel. The mortality of the welders was compared to that of the United States population as well as to that of nonwelders at the same facilities. The exposed cohort was defined as hourly male workers who had worked either as production welders or as welder helpers for 2 or more years at any of three heavy equipment manufacturing facilities in Illinois. The data indicated that welding mild steel did not increase the rate of lung cancer in this cohort when welders were compared with nonwelders at the same facility. Nor was there any trend of increased risk with increased duration of exposure in this direct comparison. Both welders and nonwelders demonstrated an increase in lung cancer compared with the United States population, but these increases were not statistically significant. It was noted that both welders and nonwelders smoked more than the United States population.
