Abstract: A welding apparatus includes a body portion, a welding part disposed on the body portion and configured to weld welding points on a to-be-welded object, and a distance measuring part disposed on the body portion and located on a side of the body portion that faces the welding part. The distance measuring part is configured to measure defocus amounts from the welding points on the to-be-welded object to the welding part. The welding part and the distance measuring part are aligned to different ones of the welding points at a same time, so that the welding part and the distance measuring part simultaneously perform welding and distance measurement on the different ones of the welding points.
