NIOSH HEALTH HAZARD EVALUATION REPORT HETA

Highlights of the NIOSH Health Hazard Evaluation Evaluation of Exposure to Welding Fumes NIOSH received a request for a health hazard evaluation (HHE) at Morton Metalcraft in Welcome, North Carolina. This request noted that employees had concerns regarding potential health effects due to exposure to welding fumes.sp.info Identifying the effects of human factors and training The use of virtual reality welding simulations may lead to heightened interest in welding among members of the gaming generation, which could lead to influx of individuals wanting to become welders. With increased numbers of potential welding trainees also comes an increase in cost of training (Mavrikios, Karabatsou, Fragos, & Chryssolouris, 2006).sp.info Evaluation of the thermal aging of δ-ferrite in austenitic Oct 10, 2018 · The resulting weld microstructure has austenite matrix, where typically 4–12% of δ-ferrite is left in the weld fusion zone to avoid hot cracking 1. The welds are usually exposed to temperatures sp.info Evaluation of the nugget diameter in spot welded joints situations because spot welding is usually completed within several seconds. On the other hand, the welding current, the welding force [ 11], the electrode displacement [12], the , electrode vibration signal [13], etc have been monitored to guarantee the quality of the spot welded joint. Thus far, we have proposed a potential drop technique uti-
