Definitions

  • Friction stir welding is a solid phase joint developed at the Welding Laboratory in the UK in 1991 [Patent Document 1].
  • the principle is that, for example, two materials (hereinafter referred to as welding members) are used as shown in Fig. 1.
  • welding members two materials
  • the screw-shaped tool into the part while rotating it at normal temperature and moving it in the welding direction
  • the welded parts of both welded members undergo plastic flow with a slight increase in temperature. This is a technology that agitates and welds the welding member.
  • Patent Document 1 Japanese patent “Patent No. 2712838 J”
  • the invention described in [00021] is a technology that attempts to achieve friction stir welding at room temperature. Knowledge regarding the plastic flow of materials, that is, materials generally tend to cause plastic flow as the temperature rises.
  • the present invention is not fully utilized.
  • the present invention actively uses the property that plastic flow easily occurs as the temperature rises. Therefore, the welding member is heated to improve the welding speed and quality. It is to try.
  • the welding member is heated so that the temperature of the welded part becomes an appropriate temperature in consideration of the temperature rise during mechanical friction stirring, and friction stir welding is performed. It is.
  • Figure 2 shows an example of the best form of the above device.
  • Figure 3 shows an example of the results of friction stir welding of an aluminum alloy using the equipment shown in [0007].
  • the vertical axis represents the welding speed and the horizontal axis represents the tool rotation speed. Shows symbols that indicate that sound welds were obtained at room temperature, 150 ° C and 300 ° C, and those where unhealthy welds were obtained. From the results of the conventional friction stir welding method at normal temperature and the results of applying the present invention, it can be seen that a heating effect of about 3.0 times is obtained when heated at 300 ° C.

Abstract

Selon l'invention, dans le soudage par friction-malaxage classique, un outil fileté en rotation est pressurisé et poussé dans une partie de soudure d'un élément de soudure à une température ordinaire et déplacé dans le sens de soudure, de sorte à induire un écoulement plastique et à obtenir le malaxage et réaliser ainsi le soudage. Le soudage par friction-malaxage classique est limité du point de vue de sa vitesse et de sa qualité. Pour résoudre ce problème, l'élément de soudure est chauffé pendant le soudage par friction-malaxage, de sorte à induire un écoulement plastique plus facilement qu'à une température ordinaire, ce qui permet d'améliorer la vitesse et la qualité du soudage.
