METHOD OF PROTECTING OPTICAL SYSTEM COMPONENTS AGAINST RAISING DUST IN ELECTRON BEAM WELDING |
摘要 |
FIELD: process engineering. ^ SUBSTANCE: invention relates to method of protecting optical system components against raising dust in electron beam welding and can be used in welding units with optical or optic-electronic process control means. Optical system comprises electron gun (1) with mirrors (2 and 3) fixed thereon, light source (4) in case (5) and video camera (6) in case (7). Mirrors (2, 3) deflect optical axis (8) of light source (4) and optical axis (9) of video camera (6) from directions (arrows (10 and 11), respectively) of line of sight of welding bath (12) from locations of said elements through angles 1 and 2. Light source (4) in case (5) and video camera (6) with case (7) are turned through angle of deflection of its optical axis by said mirrors to screen both elements from direction of line of sight of welding bath. ^ EFFECT: simple and reliable protection. ^ 2 cl, 1 dwg |
