摘要： PROBLEM TO BE SOLVED: To provide a resistance welding method capable of efficiently stabilizing the welding quality even in the case of the presence of various disturbances.
SOLUTION: The resistance welding method includes: a melt starting time detection step of detecting a melt starting time which is when at least one part of the welding portions of an object to be welded starts melting by Joule heating using electric power applied from a pressure-welded electrode; a first electric power amount calculation step of calculating the amount of the first electric power which has been applied to the object to be welded from the start of melting; and a first determination step of determining whether or not the amount of the first electric power has reached a first predetermined amount. The resistance welding method is characterized in that Joule heating is continued until the amount of the first electric power reaches the first predetermined amount. A high correlation exists between the amount of electric power which has been applied since the object to be welded started melting and a nugget to be formed. Therefore, suppressing the amount of electric power after the start of melting can efficiently stabilize the welding quality even in the case of the presence of various disturbances.
