Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] A standardized welding method for stainless steel clad plates is provided, including the following steps:

[0016] (1) Carry out blanking and scribing on the surface of the stainless steel composite plate to be welded, and it is forbidden to use needle scribing to punch holes;

[0017] (2) cutting the stainless steel plate with a cutting machine, planing off the cut edge with a planer after cutting, and performing an appearance inspection on the groove;

[0018] (3) The base layer of the stainless steel plate...

Abstract

The invention discloses a standardized welding method for a stainless steel clad plate. The method includes the steps that blanking lineation is conducted on the surface of the stainless steel clad plate to be welded, and lineation, sampling and hole punching with needles are forbidden; the stainless steel plate is cut by a cutting machine, an edge planing machine is used for planing off cut edges after cutting is completed, and grooves are subjected to visual inspection; and submerged-arc welding is adopted in a base layer of the stainless steel plate, shielded metal arc welding is adopted in other composite layers for welding, the effect that no metal is deposited onto the composite layers in the welding process of the base layer is guaranteed, and accordingly the product can be obtained. By adoption of the mode, the standardized welding method for the stainless steel clad plate can standardize stainless steel welding methods, a welding industry standard is formed, stainless steel can be welded more scientifically and correctly, and the standardized welding method can be applied and popularized.

Description

technical field [0001] The invention relates to the field of stainless steel processing, in particular to a standardized welding method for stainless steel clad plates. Background technique [0002] Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel grades that are resistant to weak corrosive media such as air, steam, and water, or have stainless properties are called stainless steel; The steel type is called acid-resistant steel. Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. The term "stainless steel" does not simply refer to one kind of stainless steel, but refers to more than one hundred kinds of industrial stainless steels, and each developed stainless steel has good performance in its specific application field. Welding is a common method in stainless ...
