The history of smoking was mean 12.33±5.24 years.Cough,sputum and dyspnoea in all patients.Poorly-defined centrilobular micronodules that were not clearly visible on chest radiographs observed on thorax HRCT.Fiber optic bronchoscopy and bronchoalveolar lavage was performed in 5 patients.Four had mixed type and one had lymphocytic alveolitis. Iron -positive pigment granules and ferruginous bodies were revealed in 3 patients' bronchoalveolarlavage.On physical examination rhonchi were present in 3 patients whose FEV1/FVC was under 70%.The other patients FEV1and DLCO values were normal.Conclusion:The cases were presented in order to create awareness to evaluate welders' chest radiography.Radiological findings on chest X-ray is not rich in welders' lung,chest physcians should look more careful to welders' chest X-ray incase of suspicious findings even at best can be detected on HRCT. %U
