A kind of brazing method between wood material and metal

Abstract

The invention discloses a brazing method between wood and metal, and relates to the field of welding. The method comprises the following steps that an aluminum oxide coating is prepared on the surfaceof to-be-brazed wood to be brazed, the to-be-brazed surface of the metal is ground, the surface of the to-be-brazed wood and the surface of the metal to be brazed are opposite to each other and the brazing filler metal foil is clamped, the wood, the brazing filler metal foil and the metal are heated, and the brazing connection between the wood and the metal is completed. The aluminum oxide coating on the surface of the wood to be brazed is prepared through a low-pressure cold spraying process. According to the brazing method, the convenience of connection between the wood and the metal can beeffectively improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a brazing method between wood materials and metals. Background technique [0002] Wooden materials are widely used in the insulation layer of low-temperature liquid cargo bulkheads of liquefied natural gas and liquefied petroleum gas transport ships. safe transport of gas. [0003] For the fixation between wooden materials and cryogenic liquid cargo bulkheads, the non-permanent connection method of mortise and tenon type is generally used, but the use of mortise and tenon joints has higher structural requirements for wooden materials and cryogenic liquid cargo bulkheads. It increases the processing and installation difficulty of the wooden material and the cryogenic liquid cargo bulkhead, and at the same time adopts the mortise and tenon connection method, there will be gaps between the wooden material and the cryogenic liquid cargo bulkhead, which will reduce the heat insulation of the c...

[0003] For the fixation between wooden materials and cryogenic liquid cargo bulkheads, the non-permanent connection method of mortise and tenon type is generally used, but the use of mortise and tenon joints has higher structural requirements for wooden materials and cryogenic liquid cargo bulkheads. It increases the difficulty of processing and installation of wooden materials and cryogenic liquid cargo bulkheads. At the same time, the connection method of tenon and tenon is adopted. There will be gaps between wooden materials and cryogenic liquid cargo bulkheads, which will reduce the heat insulation of cryogenic liquid cargo tanks.
