Abstract

PURPOSE:To improve the flatness of the steel plate surface corresponding to the visible surface to be used after the spot welding by giving the difference in the yield strength and/or the plate thickness between upper and lower steel plates with thermoplastic resin between. CONSTITUTION:The damping steel plate 1 is formed to the structure where a thermoplastic resin layer 4 is inserted between the visible surface side steel plate 2 and the invisible surface side steel plate 3 with the different plate thickness and/or yield strength in order to give the damping property. In that case, one of the plate thickness and the yield strength at least of the visible surface side steel plate 2 is made larger than that of the invisible surface side steel plate 3. Accordingly, the strain resistance of the visible surface side steel plate 2 with respect to the pressuring force of an electrode of the spot welding is improved relatively and the invisible surface side steel plate 3 can be strained preferentially. As a result, the visible surface side steel plate 2 can not be strained by straining the invisible surface plate 3 and the flatness of the visible surface side steel plate 2 can be maintained.

However, with either method of imparting weldability, the resin is first melted by raising the temperature of the steel plate and resin through preliminary energization, and the resin in the corresponding area is removed by the pressure of the welding electrode, making metal contact between the upper and lower steel plates. Welding is possible by applying the current to the steel plate, and the pressurized part of the steel plate is inevitably distorted into a concave shape, and the removed resin locally accumulates around it, causing a convex shape. It had some drawbacks.

The strain resistance of the electrode for spot welding steel plates against pressure is as follows:
It is determined by the yield strength and thickness of the steel plate, and generally the higher the yield strength, the higher the strain resistance, and the thicker the plate thickness, the higher the strain resistance. Therefore, by making the yield strength and/or the plate knob of the visible side steel plate 2 larger than the respective yield strengths and/or plate thicknesses of the mating steel plate 5 and the invisible side steel plate 3, the pressure of the spot welding electrode is increased. It is possible to relatively improve the strain resistance of the visible side steel plate 2 and to preferentially distort the mating steel plate 5 and the invisible side steel plate 3 during spot welding. Therefore, the visible side copper plate 2 is not distorted due to the distortion of the mating steel plate 5 and the invisible side steel plate 3, and the flatness of the surface of the visible side steel plate 2 is maintained.

Next, when a voltage is applied between the electrodes 6 and 6, a current flows through the conductive particles 7 in the resin layer 4 or the short circuit 8, and the temperature near the spot weld increases. begins to melt. Then, due to the load from the electrode 6, the resin near the weld is pushed out to the periphery, so the damping steel plate 1 tries to become more concavely distorted, but the invisible side steel plate 3, which can be distorted with a smaller load, takes priority. Since the steel plate 2 on the visible side is not distorted, the flatness of the steel plate 2 on the visible side is maintained.

When the resin near the weld is removed and the visible side steel plate 2 and the invisible side steel plate 3 come into metal contact, the main current flows, and a nugget 9 is formed at the joint between the damping steel plate 1 and the mating copper plate 5. These are then welded, but even after joining, the visible side steel plate 2 does not become distorted and maintains its flatness.
