Staking is the process of connecting two components by creating an interference fit between the two pieces. One workpiece has a hole in it while the other has a boss that fits within the hole. The boss is very slightly undersized so that it forms a slip fit. A staking punch is then used to expand the boss radially and to compress the boss axially so as to form an interference fit between the workpieces. This forms a permanent joint.
Welding process and battery device
The application relates to a welding process and a battery device, which comprises the following steps: penetrating at least two rivets on a welding workpiece, the welding workpiece being provided with a plurality of mounting holes; the rivets are in interference fit with the mounting holes; a rubber ring is arranged between the rivets and the welding workpiece; the welding workpiece is attached to a base material workpiece; two welding guns are respectively abutted against the rivets and are in contact with the base material workpiece; a current loop is formed between one of the welding guns, one of the rivets, the base material workpiece, the other rivet and the other welding gun; the current loop is powered according to preset process parameters, so that the two rivets are respectively fused with the base material workpiece; and the rivets, the welding workpiece and the base material workpiece are subjected to electrophoresis treatment. The welding process and the battery device have the advantages of high welding efficiency.
