Abstract: Disclosed are an infrared vision sensing detection method and device for narrow-gap weld seam deviation. The device includes a shaking (or rotating) arc narrow-gap welding torch, an arc current sensor (3), a computer image processing system (15), and an infrared photographing system. An infrared camera (11) acquires an infrared image of a welding region in an external triggering manner when an arc (1) shakes (or rotates) to a position closest to the left side wall or right side wall of a groove (9). After computer image processing, welding wire position and groove edge information is extracted in real time, and weld seam deviation is calculated according to position changes of a welding wire relative to the left side wall and the right side wall of the groove, and the weld seam deviation is output. During pulsed arc welding, a signal in a base value period of the arc current pulse is detected by using the current sensor, thereby realizing welding image acquisition synchronized with the base value current period of the pulsed arc. The device has a simple constitution, a wide application range, high weld seam detection precision, high environment adaptability, and high anti-interference capability.
