The invention provides an
underwater hybrid heat source additive manufacturing device and an application method thereof and relates to the field of
underwater additive manufacturing. The
underwater hybrid heat source additive manufacturing device comprises a
fiber laser, a
control system, a
welding robot, a
laser head, a scanning device, an underwater
laser welding torch, a gas flowmeter, an
air compressor, a
welding machine, a wire feeder, protective gas cylinders, an
optical fiber and a welding gun. The
fiber laser is connected with the laser head through the
optical fiber. The laser head isconnected with the welding
robot through a transfer board. The underwater laser
welding torch comprises an upper end cover, an inner drainage
barrel and an outer drainage
barrel. The upper end coveris provided with a welding port. A glass board is arranged on the welding port. The inner drainage
barrel is sleeved with the outer drainage barrel. The upper end of the inner drainage barrel is connected with the upper end cover in a sealed mode. The upper end cover is provided with inner drainage cavity air inlet holes. The outer drainage barrel is provided with outer drainage cavity air inlet holes. The inner drainage barrel and the outer drainage barrel are provided with wire feeding holes. The inner drainage cavity air inlet holes are connected with an
air compressor. The outer drainage cavity air inlet holes are connected with the welding protective gas cylinders. The underwater
hybrid heat source additive manufacturing device has the advantages of being simple in structure, convenient to use, high in material increasing rate, high in stability and material increasing quality and the like.
