The large problem to create manual welds of constant high quality results from missing optical information during the actual welding process. Due to the extreme brightness conditions e.g. in arc welding and the use of protective glasses even experienced welders can hardly recognize details of the welding pool, the welding seam and the environment. This paper describes a new research project for...

Eleven patients with Raynaud's phenomenon of the toes as well as the fingers were encountered among about 1,000 vibration-exposed patients. They consisted composed of four chain-saw operators, five rock drillers, a stone quarrier and a welder in a shipyard. All the cases were examined carefully for differential diagnosis, but there were no particular abnormalities in hematological, immunologica...

An Augmented Reality (AR) system integrated in a new developed welding helmet improves the conditions for manual welding. The scene is acquired by a stereoscopic High Dynamic Range CMOS (HDRC) camera system that allows the observance of the welding arc and the environment simultaneously. By image processing, the scene will be enhanced and displayed on a video see through Head Mounted Display (H...

The purpose of vision-based sensing devices in the welding industry is to electronically replicate the role of a skilled welder and emulate the human eye with a light-sensing device such as camera and the human brain with a computer algorithm that interprets the images. Just as an optical feedback from human eye guides the human welder, optical feedback in this electronic system would be used t...

Poisoning from exposure to fresh cadmium fumes at work has long been described but cases may remain undiagnosed. The diagnosis of acute cadmium poisoning should be considered in any workman who has been occupied in high temperature welding in confined spaces. Surfaces electroplated with cadmium may go unrecognised and present a significant hazard. Freshly formed cadmium oxide fumes may cause pu...
