Abstract: Provided are a welding system and a spot check method for a welding system. The welding system includes a controller, a human-machine interface, and a welding device. The spot check method for a welding system includes: controlling a rangefinder in a welding device to perform ranging, along a first direction, of at least two posts in a battery product to be welded, so as to obtain a set of ranging values between the at least two posts and the rangefinder, the first direction being parallel to an optical axis of a laser galvanometer in the welding device, the rangefinder being calibrated based on a first position in the first direction, the first position being a position of a focal point of the laser galvanometer in the first direction, and the rangefinder being at a fixed distance from the laser galvanometer in the first direction.
