Abstract
Provided is a welding position detection device capable of improving the welding position detection accuracy. The welding position detection device includes a calculation unit that irradiates two members to be joined with laser light to calculate approximate straight lines of the respective members, calculates an end portion of one member of the two members on the basis of the approximate straight line of the one member, and calculates a virtual straight line which is a straight line connecting the calculated end portion of the one member and the approximate straight line of the other member of the two members and having a specific angle with respect to the approximate straight line of the one member, and a detection unit that detects an intersection point of the calculated virtual straight line and the approximate straight line of the other member as a welding position.
