Torch for automatic gas/tungsten-arc welding provides separate coaxial views of weld to two sensors. Each sensor functions in real time without interfering with other. One sensor provides information for vision-guided seam tracker; other feeds data to an optical weld-contour monitor for control penetration. Contains beam splitter at angle of 45 degree with electrode axis. Beam splitter reflects wavelengths below 550 nm to sensor for seam tracking. Transmits wavelengths above 550 nm to sensor for weld-contour monitoring. Filters added to split beam paths to limit further spectra transmitted to sensors. Beam splitter and filters easily changed to suit material and welding parameters.
