In addition, for clearly illustrating the resistance welding projection, the size ratio of the resistance welding projection in fig. 1 and fig. 2 is larger than that in the specific implementation, and in the specific implementation, the size and the position of the resistance welding projection can be set according to the welding requirement of the resistance welding.
Referring to the drawings, fig. 1 shows a first state structure diagram of a compressor assembly, which is a structure of a compressor housing 1 and a compressor base 2 before resistance welding is performed on the compressor housing 1 and the compressor base 2. Optionally, the compressor base 1 is provided with a resistance welding protrusion 3 towards the compressor housing 2, and/or the compressor housing 2 is provided with a resistance welding protrusion 3 towards the compressor base 1. On one hand, the resistance welding bulge 2 is arranged, and the welding principle of the resistance welding bulge 2 shows that the cross section area of a circuit loop can be greatly reduced by the resistance welding bulge 2, so that the current at the resistance welding bulge 2 is increased, the position of the resistance welding bulge 2 can be rapidly fused, the welding efficiency is improved, and the certainty of the welding position is enhanced; on the other hand, the arrangement of the resistance welding bulge 2 can reduce the smoothness requirement on the contact surface of the compressor shell 1 and the compressor base 2, reduce the production cost, determine the generation position of the nugget and improve the welding quality.
