Abstract

The present invention is a kind of welding procedure of switchgear, is included the following steps:By the soldering opening wiped clean to be processed on weldment surface;The pre-heat treatment is carried out after the completion of cleaning;It is welded using tungsten electrode butt-welding fitting;It is heat-treated after being carried out to the switchgear after welding fabrication;After reaching constant temperature time, room temperature is down to the switchgear of welding fabrication and takes out weldment, that is, completes welding procedure.The present invention provides a kind of welding procedure of switchgear, by to soldering opening handle and be welded using tungsten electrode butt-welding fitting, control the welding parameter of welding gun and rear heat treatment, switchgear is effectively reduced the case where the face of weld in welding quality is recessed and solder joint deviates, improve the exterior quality of switchgear, reduce number of doing over again simultaneously, substantially increases production efficiency.

Description

A kind of welding procedure of switchgear
Technical field
The present invention relates to welding technology field more particularly to a kind of welding procedures of switchgear.
Background technology
Switchgear is a kind of electrical equipment, and main function is to be generated electricity in electric system, transmitted electricity, the conversion of distribution and electric energy During, electrical equipment is opened and closed, controlled and protected, is widely used in power plant, substation, petrochemical industry, metallurgy roll The various different occasions such as steel, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper.The process of switchgear exists at present There are face of weld recess, the defect of solder joint offset to seriously affect the exterior quality of switchgear in welding quality, while it is secondary to do over again Number is more, wastes manpower and materials, greatly reduces production efficiency.
Invention content
Present invention seek to address that the deficiencies in the prior art, and a kind of welding procedure of switchgear is provided.
The present invention to achieve the above object, using following technical scheme:
A kind of welding procedure of switchgear, which is characterized in that include the following steps:
(1) by the soldering opening wiped clean to be processed on weldment surface, ensure clean free from admixture;
(2) it polishes and disposes the metal oxide film for processing 20-30mm ranges around soldering opening on weldment surface, between weld seam Gap control is 0.3-0.6mm, and the pre-heat treatment is carried out after the completion of cleaning, and preheating temperature control is 400-450 DEG C;
(3) it after preheating, is welded using tungsten electrode butt-welding fitting, control resistance welding gun electric conducting nozzle is at a distance from soldering opening 0.6-0.9mm, the speed of welding for controlling welding gun are 25-35cm/min;
(4) it is heat-treated after being carried out to the switchgear after welding fabrication, cabinet is placed in electrical heating case, control electrical heating case Ranging from 6-10 DEG C/min of heating rate, temperature rises to 400-450 DEG C, and it is 30-45min to control constant temperature time;
(5) after reaching constant temperature time, room temperature is down to the switchgear of welding fabrication and takes out weldment, that is, completes welding procedure.
Particularly, the pre-heat treatment in the step (2) carries out the pre-heat treatment using manual grilled gun.
The beneficial effects of the invention are as follows:The present invention provides a kind of welding procedure of switchgear, to soldering opening It manages and tungsten electrode butt-welding fitting is used to be welded, control the welding parameter of welding gun and rear heat treatment, effectively reduce switchgear and exist The case where face of weld recess and solder joint in welding quality deviate, improves the exterior quality of switchgear, reduces simultaneously It does over again number, substantially increases production efficiency.
Specific implementation mode
With reference to embodiment, the invention will be further described:
