Aluminum alloy shell of switch equipment and manufacturing method of aluminum alloy shell

The invention relates to the technical field of conductor welding, in particular to a switchgear aluminum alloy shell and a manufacturing method thereof.The manufacturing method of the switchgear aluminum alloy shell comprises the steps that a barrel and a flange of the aluminum alloy shell are in butt joint, and the junction of the peripheral face of the barrel and the end face of the flange is a welding position; the welding positions of the cylinder and the flange are riveted in a laser welding and welding wire adding mode, and the number of riveting points in the circumferential direction is not more than 3; a laser welding process is adopted for welding at the welding position of a barrel and a flange, during laser welding, a laser welding head is adjusted to enable the included angle between the laser welding head and the end face of the flange to be 25-35 degrees, the laser power is not smaller than 9 kW, the light spot diameter is 3-5 mm, the defocusing amount is minus 3-0 mm, the welding speed is 2-2
