A detector for a welding flaw of a spiral welding pipe using laser is provided to objectively detect the welding flaw by realizing an artificial intelligence type detection system. A detector for a welding flaw of a spiral welding pipe using laser includes an ultrasonic oscillation unit, an ultrasonic sensor position control unit, and a control unit. The ultrasonic oscillation unit oscillates ultrasonic waves on a surface of a spiral welding pipe(10) by using YAG laser and receives the ultrasonic waves. The ultrasonic sensor position control unit detects the welding flaw by pursuing a welding line. The control unit determines the defect by analyzing a welding defect signal in real time.
