Underwater hybrid heat source additive manufacturing device and application method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of underwater additive manufacturing, and in detail relates to a composite heat source additive manufacturing device with simple structure, convenient use, fast additive speed, high stability and high additive quality and a method for using the same. Background technique [0002] my country is a large maritime country, and the navy is an important armed force for defending the ocean. In order to ensure the rapid recovery of combat functions and combat effectiveness of damaged ship equipment in actual combat, the extension of ship equipment maintenance from shore-based fixed-point support to offshore mobile support is realized. , It is necessary to develop equipment and key technologies for ship emergency maintenance. For the emergency repair of the hull, it can be divided into two types: maintenance above the waterline and underwater maintenance in terms of damage location. With the improvement of ship maint...

AI Technical Summary

Problems solved by technology

However, so far, there are few reports on the additive manufacturing technology of underwater laser arc composite heat source. The emergency repair capability of my country's naval ship equipment is still very limited, and there is a serious lack of key technologies and equipment for underwater operations of ship repair.
