Abstract: The present disclosure relates to the technical field of welding, and particularly relates to a welding method for sealing a cooling-water channel of an electric-machine housing. The method includes the steps of: 1) seal the opened ends of the cooling-water channel using the sealing parts to form an S-shaped sealed cooling water channel inside the electric-machine housing; and 2) weld each of the sealing parts and the electric-machine-housing together by using the friction-stir-welding, in one single and complete single-welding-seam mode. The present disclosure utilizes the stirring head having a larger diameter to sufficiently stir-weld each of the sealing parts and the electric-machine housing all at once, i.e., welding in the single-welding-seam mode, so that the welding can be completed at one time, which, as compared with the conventional mode of double-welding-seam mode, has a higher operation efficiency, a better stability, and reduces welding duration by ½ to ⅓.

Abstract: The present disclosure discloses an electric-machine housing, which effectively solves the technical problem in the prior art that electric machines have high NVH level. The electric-machine housing is circumferentially provided with a plurality of axial tunnels, and the tunnels are empty or are filled with a damping medium. The structure in which the tunnels are empty or the tunnels are filled with the damping medium can weaken the excitation to the electric-machine housing by the stator vibration, increase the damping coefficient of the electric-machine housing, weaken the transfer paths of vibration and noise, and reduce the amplitude of electromagnetic force waves, thereby inhibiting vibration and noise, to effectively reduce the overall NVH level.
