Embodiment Construction

[0022] as shown

[0023] Such as figure 1 , figure 2 The drainage device for underwater laser welding shown includes an upper end cover 1, a cylindrical drainage cover 9 and a drainage sealing gasket 5. The middle part of the upper end surface of the upper end cover 1 is provided with a welding port 16 that penetrates up and down, and the welding port 16 is sealed and installed. There is glass plate 14, and described glass plate 14 is antireflection glass plate, from figure 1 It can be seen from the figure that the anti-reflection glass plate is installed on the upper side of the welding joint of the upper end cover through the anti-reflection glass frame 15, and a sealing ring 13 is arranged between the anti-reflection glass frame 15 and the upper end cover; the anti-reflection glass frame 15 is installed through external threads On the internal thread at the welding port of the upper end cap. The inner side wall of the upper end cover 1 is provided with an annular gas bu...

Abstract

The invention discloses a drainage device used for underwater laser welding. The drainage device includes an upper end cover, a distance adjusting shell, a drainage shell and a drainage sealing pad. The upper end cover is provided with anti-reflection glass, an anti-reflection glass frame, an anti-reflection glass arrangement groove, a sealing ring, a drainage air hole, an air buffer slot, and a metal sieving net. The distance adjusting shell is connected with inner threads of the upper end cover through outer threads. The drainage shell is connected with the distance adjusting shell through outer threads. The drainage sealing pad is connected with the bottom of the drainage shell through a clamping hoop. The drainage device is simple in structure arrangement, convenient to operate, economical and practical; a stable local drying space can be formed on the surface of an underwater workpiece to be welded; the problem that underwater laser welding is influenced by water environment is effectively solved; and underwater laser welding is achieved.

Description

technical field [0001] The invention relates to the field of underwater laser welding, and in detail relates to a drainage device for underwater laser welding and a use method thereof, which has a simple structure, is easy to use, and can obtain a stable underwater local dry space. Background technique [0002] With the development of human activities into deeper and farther ocean areas and the widespread use of new materials, traditional underwater welding methods are increasingly restricted. Therefore, it is of great practical significance to vigorously develop underwater welding technology and make abundant marine resources serve human beings. [0003] Laser is known as "the fastest knife", "the most accurate ruler" and "the brightest light". It has the characteristics of strong directionality, high brightness and good monochromaticity. It is widely used in laser welding, laser cutting, surface Modification, laser marking, laser drilling and laser micromachining. Laser ...
