[0002] At present, the structure of the cooling pipe of the radiator tank of the automobile is mostly a single-layer material with high-frequency welding, or a lap pipe without high-frequency welding; The material at the small fillet will be bent and deformed, and then the single-layer material will be welded or brazed. The mechanical properties of the welded single-layer material will be reduced, so the corrosion of the radiator tank, Most of the water leakage occurs at the single-layer bending fillet of these cooling pipes, which reduces the service life of the radiator

Embodiment 1
[0023] The end of the outer plate 6 of the lap joint is closed with the bottom of the straight arm of the right material plate 2, and the center line of the welding point of the welding part at the upper end of the left material plate 1 and the welding part at the upper end of the right material plate 2 forms an angle of 0 degrees with the vertical line or An 85-degree angle to the left or an 85-degree angle to the right.
Embodiment 2
[0025] The end of the outer plate 6 of the lap joint and the bottom of the straight arm of the right material plate 2 are not closed, and the center line of the welding point of the welding part at the upper end of the left material plate 1 and the welding part at the upper end of the right material plate 2 forms an angle of 0 degrees with the vertical line Either at an 85-degree angle to the left or at an 85-degree angle to the right.

The invention relates to a fillet overlap joint enhancing high-frequency welded tube. The fillet overlap joint enhancing high-frequency welded tube comprises a left material plate and a right material plate which are encircled to form a tubular body, double-layer structured welding portions are arranged at the upper ends of the left material plate and the right material plate, and the upper end of the left material plate and the upper end of the right material plate are welded integrally through the welding portions; overlap joint portions are arranged at the lower end of the left material plate and the lower end of the right material plate, and the lower end of the left material plate and the lower end of the right material plate are overlapped integrally through the overlap joint portions. The fillet mechanical strength of the welding portions can be enhanced by virtue of the double-layer structures formed by inner plates and outer plates of the welding portions; the mechanical strength of the fillets in the overlap joint portions can be enhanced by virtue of the double-layer structures formed by inner plates and outer plates of the welding portions; before the welding portions are welded, the outer plates of the overlap joint portions cover the inner plates of the overlap joint portions by virtue of an overlap joint process first, so that the outer plates and the inner plates are engaged integrally, thereby facilitating welding and positioning the welding portions; the mechanical strength of the bending fillets of a cooling tube is effectively enhanced, and welding production is facilitated.
Description
technical field [0001] The invention relates to the technical field of production of automobile cooling pipes, in particular to a high-frequency welded pipe reinforced with rounded corners and lap joints. Background technique [0002] At present, the structure of the cooling pipe of the radiator tank of the automobile is mostly a single-layer material with high-frequency welding, or a lap pipe without high-frequency welding; The material at the small fillet will be bent and deformed, and then the single-layer material will be welded or brazed. The mechanical properties of the welded single-layer material will be reduced, so the corrosion of the radiator tank, Most of the water leakage occurs at the single-layer bending fillets of these cooling pipes, which reduces the service life of the radiator. [0003] Therefore, it is necessary to design a high-frequency welded pipe structure that can effectively strengthen the mechanical strength of the bending fillet of the cooling p...
