Resistance spot welding of AISI 201 stainless steel: The relationship between welding current, microstructure, mechanical properties and failure mode
In this paper, resistance spot welding process of AISI 201 stainless steel is studied experimentally. For this purpose, effect of welding current on quality of weld is investigated and relationships between welding current and fusion zone characteristics are examined. For determining mechanical properties such as maximum load and fracture mode, tensile - shear test of spot welds is performed. ...
متن کاملBuckling of Cylindrical Steel Shells with Random Imperfections due to Global Shear
This study aims to investigate the effects of geometric imperfections on buckling of thin cylindrical shells due to global shear. To this end, more than 320 finite element models of cylindrical shells with different diameter to thickness ratios were prepared. Random imperfections with different amplitudes were applied to numerical models. The results revealed that global buckling of cylindrical...

متن کاملMassive hemoptysis due to welding fumes
UNLABELLED Many pulmonary problems such as lung cancer, occupational asthma, and pneumoconiosis have been described due to welding in the literature until now. This is the first case report of alveolar hemorrhage due to welding fumes presented with massive hemoptysis. We report a rare case of massive hemopthisis associated with welder's lung, with a discussion based on a review of the literatur...
متن کاملBilateral Macular Hemorrhage Due to Welding Arc: A Case Report
Background and Objective: Non-ionized radiation from arc welding may cause retinal lesions such as photo retinitis. In this report, a patient with bilateral macular bleeding which had been caused by inappropriate use of protective safety glasses is introduced. Case Report: On 26 July 2008 a 23-year-old male with blurred vision was referred to Shahid Beheshti's faculty of Rehabilitation Clinic....
