Abstract
The invention discloses an electroslag welding method for special-shaped sections. A plurality of corresponding tooling plates are connected to welding ends of two shaft welding parts or triangular welding parts required to be abutted, welding surfaces of the two shaft welding parts or triangular welding parts required to be abutted are turned into square or rectangular sections, the electroslag welding method is carried out, finally, all the tooling plates are removed, and welding is completed. By the aid of the tooling plates, the special-shaped sections are turned into the square or rectangular sections, so that electroslag welding can be implemented, the method reduces requirements of electrowelding on sections, a feasible path is provided for welding super-thick parts with various sections, and production efficiency is greatly improved.
Description
Technical field
The invention belongs to plant equipment manufacturing technology field, relate to a kind of electroslag welding method of odd-shaped cross section.
Background technology
In plant equipment is made, often can use electroslag welding method, electroslag welding method is the method that the resistance heat that utilizes electric current to be produced through the liquid slag welds, and is divided into vertical masonry joint electroslag welding and circumferential weld electroslag welding dual mode.It is rectangle or square that vertical masonry joint electroslag welding wherein requires the connection cross section of two soldering parts, and main forms is the butt joint of two blocks of steel plates; And the connection cross section of two soldering parts of circumferential weld electroslag welding requirement is an annular, and main forms is the butt joint of tubular or cylinder class part.
Owing to adopt electroslag welding once to weld completion for big thickness workpiece, welding productivity is high, and the electroslag welding weld seam to produce the tendentiousness of pore, slag inclusion lower, therefore use wider to the heavy duty equipment manufacturing.But the complex section of above-mentioned two kinds of electroslag welding method pair cross-sections such as other shapes such as axle class, triangle can not directly be suitable for, and has largely limited the abundant use of electroslag welding.
Summary of the invention
The electroslag welding method that the purpose of this invention is to provide a kind of odd-shaped cross section has solved existing electroslag welding method and can only adapt to vertical masonry joint electroslag welding and circumferential weld electroslag welding, and pair cross-section requires comparatively harsh problem.
The technical scheme that the present invention adopted is, a kind of electroslag welding method of odd-shaped cross section,
First kind of mode; The corresponding a plurality of frock plates of connection in the axle type weldment welding termination of two needs butt joint change into square the solder side of the axle type weldment of two needs butt joints or the square-section, carry out according to electroslag welding method again; Remove all frock plates at last.
The second way; Triangle weldment two needs butt joints welds the corresponding frock plate of connection of termination, and the triangle weldment solder side that two needs are docked changes into square or the square-section, carries out according to electroslag welding method again; Remove all frock plates at last.
The invention has the beneficial effects as follows, expanded the scope of application of electroslag welding, feasible solution route is provided, improved production efficiency greatly for the welding of the ultra-thick part in various cross sections to the weldment cross section.
Description of drawings
Fig. 1 is the used frock plate schematic cross-section of the inventive method;
Fig. 2 be apparatus of the present invention instance change into rectangle or square-section stereogram;
Fig. 3 be the inventive method the butt joint schematic cross-section of two axle class weldments that will weld.
Among the figure, 1. a class weldment, 2. frock plate, 3. triangle weldment.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
The electroslag welding method of odd-shaped cross section of the present invention; When implementing, need use the supporting frock plate 2 in axle class weldment 1 cross section that will weld with institute; With reference to Fig. 1; Four frock plates 2 are combined into a rectangle or a square plate that has intermediate throughholes, and middle through hole is consistent with the outside diameter of the class weldment 1 that institute will weld.
The electroslag welding method of odd-shaped cross section of the present invention, before implementing welding, the relative termination of the axle type weldment 1 that two institutes will be welded respectively with frock plate 2 (four) splicing, frock plate 2 is concordant with an end face of class weldment 1, like the type of attachment of Fig. 2; With two axle type weldment 1 butt joint assemblings that the cross sectional shape size is similar and different, to being connected into the form like Fig. 3, two axle class weldment 1 axle center are relative again, and the end face contact is welded into an integral body through electroslag welding method with the two-section axial workpiece then; Last remove all frock plates 2 again.
Like Fig. 4, Fig. 5; For lateral cross section is leg-of-mutton triangle weldment 3, need the triangular-section of two frock plates 2 and triangle weldment 3 be combined into square or rectangle, adopt above-mentioned method to carry out electroslag welding again; Last two the frock plates 2 that added that remove again.
The electroslag welding method of odd-shaped cross section of the present invention; Multiple complex cross-sectional such as axle class, triangle are changed into rectangle or square-section; Be able to the condition of smooth implementation electroslag welding; The inventive method has been expanded the adaptability requirement of electroslag welding to axle class weldment, triangle weldment cross section, and for the welding of the ultra-thick part of other similar cross-section shapes feasible method is provided, and has improved production efficiency greatly.
