Abstract�� In a plane factory, some tubes connection is in the plane by welding. Traditional induction brazing device with a fixed coil could not adapt this new process. Considering the characteristic of on-site induction brazing of tubes, a set of equipment and related technologies were developed, including a special low loss connecting power cable,a precise measurement and control system of brazing temperature with a fiber,and an ultrasonic induction heating inverter, and necessary experiments were done. The results show that this device and related technologies can satisfy the welding quality and is successfully applied in the factory.
Keywords�� induction brazing   tubes connection   inverters   temperature control   connecting power cable
