Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] Such as figure 1 As shown, the groove should be opened before the stainless steel plate is hoisted and paved; the hook on the hanging row hangs the stainless steel plate on the jigsaw tire frame in turn to control the total size of the jigsaw board and adjust the distance between the stainless steel plate and the stainless steel plate. the gap between.

[0030] figure 2 Welding for the tack welding of the present invention: at first add arc-starting plate and arc-extinguishing plate at both ends of the butt weld, and strike the arc on the arc-starting plate; secondly, on the stainless steel plate, fix it on the jigsaw tire frame with a briquetting block, and then Stagger the welds sequentially.

Abstract

The invention relates to a method for preparing a stainless steel jointed board, in particular to a method for preparing a stainless steel jointed board for shipbuilding. The method includes the steps: hoisting a stainless steel board; performing positioned welding and positioning; performing formal welding; and turning over the board after single-side welding and welding the other side of the board. By the aid of the method, the problem of deformation in the processes of hoisting, welding and jointing of the stainless steel board can be effectively controlled, an oxidation film is well protected, and the stainless steel board is free of the defects of scratch, damage and the like in the processes.

Description

technical field [0001] The invention relates to a preparation method of a stainless steel panel, in particular to a preparation method of a stainless steel panel used in shipbuilding. Background technique [0002] As a high value-added chemical tanker, most of them use stainless steel as the inner tank. Stainless steel is characterized by high strength and sensitivity to heat. There is a very thin oxide film on the surface of stainless steel, which makes stainless steel have good corrosion resistance. The damage of the oxide film will seriously reduce the corrosion resistance of stainless steel; in addition, carburization will also reduce the corrosion resistance of stainless steel. Therefore, for stainless steel materials, great attention should be paid to the protection of the surface, especially the protection of the inner surface of the cargo tank. Therefore, effective protection measures must be taken in all links such as hoisting, welding, and jigsawing to protect t...
