Comparing flash and butt welding - The FABRICATOR

Flash welding and butt welding are resistance welding processes in which coalescence is produced simultaneously over the entire area of two abutting surfaces. In both processes, heat for welding is obtained by the resistance to electric current between the two facing surfaces. This article explains ...

Welding - Radiation and the Effects On Eyes and Skin : OSH ...

The amount of time required to cause these effects depends on several factors such as the intensity of the radiation, the distance from the welding arc, the angle at which the radiation enters the eye, and type of eye protection that the welder or bystander is using. However, exposure to just a few seconds of intense UV light can cause arc eye.
