[0002] In bridge engineering, such as arch bridges, cable-stayed bridges, and suspension bridges, static and dynamic monitoring of their cables, supports, and other components is a crucial means to ensure the normal and safe construction and operation of the bridge. Monitoring bridge safety can be achieved by deploying tubular sensors, such as fiber optic grating sensors, in bridge components like cables and supports.

[0003] When fabricating tubular sensors, a capillary metal sleeve needs to be fixed to a metal substrate. There are various fixing methods, and currently, welding effectively ensures the sensor's survival rate and stability. However, during the welding process, using traditional welding machines results in unstable current, easily burning through the metal substrate, and poor operational stability, leading to uneven weld distribution, significantly reducing the survival rate and stability of the tubular sensor. Spot welding machines have also been used, but the problem of poor operational stability remains.

First, the capillary metal tube 22 is placed in the positioning groove 19, and then the metal foil 21 is placed on top of the capillary metal tube 22 in the positioning groove 19. According to the thickness of the metal foil 21, the required current and pulse intensity are adjusted by clicking the adjustment button 11. The sliding base 8 is manually slid smoothly on the left and right slide rails 6 and the front and rear slide rails 7 so that the metal foil 21 is directly below the welding needle 18. The foot pedal pressure plate 5 is stepped on to apply pressure. At this time, the current flows through the wire 10. The lifting rod 12 moves and drives the rotating rod 13 to rotate. Through the action of the spring 16, the machine head 17 is lowered, and the welding needle 18 and the metal foil 21 come into contact and form a heat fusion at the contact point. The welding needle 18 leaves a weld point on the metal foil 21, so that the metal foil 21 and the capillary metal tube 22 are welded together.
