To solve the above problems, the technical solution adopted in the utility model is：
A kind of welding point of the connection ring and pedestal of high speed motor car oil-pressure damper, including：Connection ring and pedestal,
In,
The pedestal is in class taper, including：First gradual change portion and the second gradual change portion, first gradual change portion with it is horizontal
Angle is 50 ~ 70 °, and second gradual change portion and horizontal angle are 20 ~ 40 °；
Angle is formed between first gradual change portion and second gradual change portion；
The weld part setting of the connection ring and the pedestal there are four chamfered portion, the chamfered portion with it is described
Angle cooperation welding.
Further, first gradual change portion is located at the top in second gradual change portion.
Further, first gradual change portion and horizontal angle are 60 °.
Further, second gradual change portion and horizontal angle are 30 °.
Further, the pedestal includes：High speed motor car protective cover seat and the outer cylinder seat of high speed motor car.
The beneficial effects of the utility model are：Increase two chamfered transitions, the groove face bigger of pedestal and connection ring,
Weld metal is more preferable to the wetability of base material；Increase with the angle of the contact surface of pedestal at the chamfering of connection ring, increases weld seam
The loading of metal.Weldquality greatly improves.
