OBJECTIVES The aim was to compare the peak expiratory flow (PEF) of welders and non-welders over a 12 hour period from the start of work on Monday. METHODS The two study groups consisted of 20 welders and 20 non-welders, all men who had essentially never smoked, with no significant difference in age, height, ethnicity, or baseline spirometry between the groups. The PEF was measured for each w...

Understanding the impact of welding parameters and welder skill on weld quality is crucial. However, it lack comprehensive studies that consider welder-introduced defects when analyzing mechanical metallurgical behaviors low carbon steel welds using SMAW process. The research aims to study assess seams ABS Grade A marine plate 12.7mm thick manual process as per AWS D1.1 structural code requirem...

According to the International Atomic Energy Agency (IAEA), industrial radiography accounts for approximately half of all reported accidents for the nuclear related industry. Detailed information about these accidents has been published by the IAEA in its Safety Report Series, one of which describes the radiological accident which happened in 1999 in Yanango/Peru. Under unsettled circumstances ...

PURPOSE This study was performed to investigate whether occupationally related color vision deficiency can occur from welding. METHODS A total of 50 male welders, who had been working as welders for at least 4 years, were randomly selected as case group, and 50 age matched non-welder men, who lived in the same area, were regarded as control group. Color vision was assessed using the Lanthony ...

Pterygium is thought to be hyperaemia of fibrovascular tissue on to the cornea caused by ultraviolet radiation of sunlight. We observed a significantly high incidence of pterygia in welders who were exposed occupationally to excess ultraviolet radiation and found a close relationship between the incidence and the length of employment as a welder (r = 0.975, p less than 0.05). This study attempt...
