Embodiment Construction
[0013] Such as Figure 1-Figure 2 As shown, a lightning rod for high-rise buildings includes a needle bar 1, a metal ball 2 and a needle tip part 3, an insulator 4 is fixed on the bottom of the metal ball 2, and the insulating character 4 is made of ceramics, and a round hole is provided inside, so that the needle bar 1 The top can go through. The metal ball 2 and the insulator are welded by brazing process, which can keep the surface of the joint clean, good air tightness, stable shape and size, the structure and performance of the weldment do not change much, and the same or different metals and some non-identical parts can be connected. Metal. During brazing, the overall heating of the workpiece can also be used, and many welds can be welded at one time, which improves the productivity. However, the strength of brazed joints is low, and lap joints are mostly used, and the strength of the joints is increased by increasing the length of the lap; in addition, the preparation...
