Device for clad welding of boiler tube walls using metal active gas welding, comprises two consecutive burners intended on an oscillating device in a welding direction, and drive device for moving oscillating device at a welding speed

摘要

The device comprises two consecutive burners (20, 21) intended on an oscillating device (23) in a welding direction, and a drive device (29) for moving the oscillating device at a welding speed on a predetermined, straight path. A burner mounting plate (22) and the oscillating device are installed on a rail-guided carriage, which is displaceable via cable pulleys by the drive device along the rails. A person basket is arranged at the carriage. The burners are secured to the oscillating device by a multiple carriage arrangement. The oscillating speed/frequency is automatically controllable.
