The invention discloses a manufacturing method of an aluminum/titanium/nickel/stainless steel four-layer composite board for an LNG (Liquefied Natural Gas) carrier. The aluminum/titanium/nickel/stainless steel four-layer composite board which has excellent performance is manufactured through three times of layered explosive welding by adopting an explosive welding technique. The arrangement method of different materials at four layers disclosed by the invention not only fully considers the mechanical property of mutual bonding of the different materials during manufacturing through explosive welding but also fully utilizes the difference of the heat conductivity of the different materials, so that the four-layer composite materials are enabled to become materials with gradient heat conductivity, the conduction control of the heat of manufactured four-layer composite transition joints during fusion welding is facilitated and the reliability of the mechanical structure of the bonding interfaces of the materials
