Embodiment Construction

[0021] A kind of welding technology of 0Cr18Ni9 stainless steel plate, the thickness of steel plate is 4mm, it is characterized in that: comprise the following steps:

[0022] (1) Preparation before welding

[0023] First, the pre-welding treatment of the weldment, remove the accumulated water and snow on the surface of the weldment, ensure the dryness of the weldment, and remove the dirt on the surface of the weldment, such as a block of rust oxide, oil, etc.;

[0024] Second, the selection of welding methods and welding materials, manual arc welding is used for welding, and the welding rods are E308-16 type A102 welding rods, and the diameter of the welding rods is 3.2mm;

[0025] Third, dry the used welding rod, first put the welding rod into a furnace with a temperature below 100°C, then slowly raise the temperature to 150°C, keep it warm for 1 hour and then cool slowly with the furnace;

[0026] (2) Temporary spot welding

[0027] First, use an AC welding machin...

Abstract

The invention discloses a 0Cr18Ni9 stainless steel plate welding process, and relates to the technical field of welding processes. The 0Cr18Ni9 stainless steel plate welding process mainly includes the steps of preparation before welding, tack weld, welding and treatment after welding. By means of the 0Cr18Ni9 stainless steel plate welding process, the welding steps are simplified, a welding mode is simple, material selection is precise and standard, the welding quality of 0Cr18Ni9 stainless steel plates can be guaranteed, the standard welding mode is provided for the 0Cr18Ni9 stainless steel plates, and quick and safe welding of the 0Cr18Ni9 stainless steel plates is facilitated.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to a welding technology of 0Cr18Ni9 stainless steel plate. Background technique [0002] Different welding methods have different welding processes. The welding process is mainly determined according to the material, grade, chemical composition of the workpiece to be welded, the structure type of the weldment, and the welding performance requirements. First of all, it is necessary to determine the welding method, such as manual arc welding, submerged arc welding, argon tungsten arc welding, gas metal arc welding, etc. There are many types of welding methods, which can only be selected according to specific conditions. After the welding method is determined, the welding process parameters are formulated. The types of welding process parameters are different. For example, manual arc welding mainly includes: electrode type (or grade), diameter, current, voltage, type of wel...
