  • WELDING OBSERVATION DEVICE
    Publication number: 20100206851
    Abstract: A welding observation apparatus is provided to use partial darkening by a telecentric optical system and a photochromic filter (PCF) as an optical system for filtering light emission from arc discharge in order to verify the welding condition under the welding arc discharge, without forming an image on the PCF, so that light reducing performance can be secured even if a focus shifts from on the PCF, with satisfactory monitoring of welding condition. The welding observation apparatus comprises: an arc welding unit 8; an objective optical system (1, 2) for concentrating light from the arc welding unit 8; a telecentric optical system 3 for guiding the light concentrated by the objective optical system (1, 2); a PCF 4 for illuminating with the light guided by the telecentric optical system 3; and a solid state imaging device 9 for receiving the light passing through the PCF 4, wherein the light from the arc welding unit 8 is partial-darkened by the PCF 4.
