Pyrogenic factors of the fumes collected during arc welding process

Stainless steel manual metal arc welding fumes in rats.

Forty two male Wistar rats were exposed to manual metal arc (MMA) stainless steel (SS) welding fumes generated by an automatic welding device for "nose-only" exposure. The exposure simulated an actual MMA/SS welding environment as closely as possible. For the retention study, the duration of exposure was one hour per workday for one, two, three, of four weeks and for the clearance study four we...

urinary β2 microglobulin in workers exposed to arc welding fumes

welding is a process in which two or more metals are attached by the use of heat and, in some cases, pressure. direct exposure and inhalation of welding fumes causes acute and chronic side effects in humans. kidney damage is one of these important side effects. β2 microglobulin is an 11.8 kilodalton protein and levels increase in the case of some inflammatory and viral diseases, or kidney malfu...

Thermaltransport Phenomenon of Submerged Arc Welding Process

Original scientific paper In present work, thermal transport considering heat radiation by oval heat source shape and heat transfer of molten moving electrode was presented. In present paper, an analytical solution was presented by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions for the study were heat source of temperat...

Monitoring of Arc Welding Process Based on Arc Light Emission

Visual Sensing Systems for Arc Welding Process

Visual sensing technology is widely used in welding practices because visual devices are decreasing in price, increasing in reliability and improving in image processing hardware and software. As the most studied welding sensor, CCD(Charge Coupled Device) is more suitable for quality control of welding process than other means of sensing devices because it can obtain both two dimensional and th...
