Occupational exposure to welding gases during three welding processes and risk assessment by SQRCA method

Background: Hazardous chemical agents in the welding operation are a mixture of metal fumes and toxic gases, the inhalation of which causes adverse health effects among welders. The emission of gases in the workplace is a logical cause for concern regarding the potential development of respiratory disease. The aim of the present study was to determine the concentration values of gases discharge...

Intelligent Systems in Welding Processes

The demand for better control and sensing in welding has increased with automation and welding processes involving new and advanced materials. This requires precise control of the welding process to produce the desired weld with respect to productivity and quality. This papers describes sensors for technological and geometrical parameters for welding process.

Visual Analysis of Welding Processes

TECHNICAL COMMISSION III: Theory and Algorithms

There is an increasing trend of using several different sensors in data acquisition, including non-optical sensors. As a consequence, data and extracted information must be combined. Solutions to this fusion problem are offered on several levels, for example on the sensor level (sensor integration, geo-registering, data fusion), feature level, or symbolic level. Such a neat separation is desira...
