摘要： The first embodiment of the invention is a spot welding method using a welding gun including a pair of electrodes holding and welding a welding point of a workpiece. The method including: transmitting an ultrasonic from one of the electrode pair to the workpiece with the electrode pair holding the workpiece; receiving the ultrasonic at the other electrode passed through the electrode pair and the workpiece; and detecting a holding state of the workpiece on the basis of an amplitude of the received ultrasonic. According to the embodiments of the invention, the welding gun can hold the workpiece at the proper position and with the correct angle, thereby reducing the welding flaws.

摘要： A resistance welding method according to the invention includes: a melting start time specification process for specifying a melting start time, which is a time at which at least a part of a welding portion of a welding subject starts to melt while being subjected to Joule heating by a power input from an electrode pressed against the welding subject, by detecting a variation in an ultrasonic wave emitted toward the welding portion; a first power amount calculation process for calculating a first power amount, which is an integrated value of the power input into the welding subject via the electrode from the melting start time; a first determination process for determining whether or not the first power amount has reached a first set value; and a heating process for performing the Joule heating from the melting start time until the first power amount reaches the first set value.
