The aim of this study is to assess the levels of airborne ultrafine particles emitted in welding processes (tungsten inert gas [TIG], metal active gas [MAG] of carbon steel, and friction stir welding [FSW] of aluminum) in terms of deposited area in pulmonary alveolar tract using a nanoparticle surface area monitor (NSAM) analyzer. The obtained results showed the dependence of process parameters...

A 3-D finite element model is used to simulate water jet spot welding. The simulation is validated using the experimental data obtained by one of authors with other workers. The simulations identify parameters which correlate well with the quality of the welds produced. In particular the levels of equivalent plastic strain (PEEQ) and shear stress directions are shown to predict whether or not t...

OBJECTIVES Arc welding produces the full spectrum of ultraviolet radiation and may be a contributory cause of skin cancer; however, there has been little research into this occupational hazard. The aim of this study is to explore if metal arc welding increases the risk of malignant melanoma and/or basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) on skin areas which may possibly be e...

<p><em>Welding workers are potentially exposed to cadmium containing fumes during the welding process. Cadmium is one of heavy metals that considered toxic. can interfere with health body organs such as kidneys. Accumulation in kidneys decrease excretory activity veins. Resulting impact an increase uric acid levels (hyperuricemia). This study aims determine relationship between hair...

Lead (Pb), a toxic contaminant metal used in many important industrial processes, is widely used in batteries, paint vanishes, in pipe covering and in welding. The exposure showed a high risk of human health and development of several types of cancers. A total of 64 male workers in Hyderabad battery unit in Mahaboobnagar District, Andhra Pradesh were investigated for genetic damage in buccal ce...

Welding is risky work that can cause eye fatigue so endanger workers. The purpose of this study was to determine the relationship worker factors and welding light intensity with on workers production section. This type research descriptive quantitative a cross sectional approach by measuring independent variables (worker intensity) dependent (eye fatigue). results indicate associated are age (p...
