Abstract
The utility model discloses a kind of novel welding structure that skirt is connect with end socket, it includes end socket and skirt, built-up welding forms overlay cladding on end socket, and overlay cladding includes overlay cladding fillet, overlay cladding outer circle and overlay cladding groove, and the weld seam between overlay cladding groove and skirt is fillet.This practical new connection by skirt and end socket is improved to complete overlaying structure from conventional welding structure; completely new welding node is devised, overlaying structure is using tooling built-up welding on designed end socket, after built-up welding; again with conventional machine-tooled method by figure processing fillet; last skirt and overlay cladding weld, it is therefore prevented that stress concentration, welding deformation avoid the damage of end socket base material; success rate is higher; it is simple and efficient connection procedure, base material is protected, improves processing progress；Skirt and end socket junction need equipment with rounded corners in the especially suitable fatigue vessel of the welding structure.
Description
Technical field
The utility model relates to the novel welding structures that a kind of skirt is connect with end socket, are widely used in petrochemical industry
Diameter it is small, the high vertical skirt fatigue vessel of skirt.
Background technique
The installation of general vertical skirt fatigue vessel is first assembled using skirt with end socket, then by a section skirt with it is assembled
Closing end component welding lifts the component installation positioning of completion, is finally machined out to the weld seam between skirt and end socket.Due to
The reason of fatigue load, the weld seam of the junction of the skirt and end socket of fatigue vessel stress easy to form are concentrated, are produced fracture, shadow
Ring service life of equipment.In order to solve this problem, it is necessary to an a fillet of processing in the commissure, and skirt 3 as shown in Figure 1
It is easy to destroy 1 base material of end socket when processing 2 fillet of weld seam with the normal welding structure of end socket 1, once base material is impaired, to entire
The influence of the schedule of deliveries of project is fatal, and small for diameter, the high fatigue vessel of skirt, the characteristics of due to its own,
It is accurately positioned extremely difficult, while space is limited in container, and operator's adjustment difficult to get access causes machining accuracy low.
Utility model content
It is easy to solve weld seam fillet difficult processing existing for normal welding structure of the skirt with end socket junction and end socket base material
The problem of damage, the utility model provide a kind of novel welding structure that skirt is connect with end socket, can discharge concentrated stress, delay
Fatigue vessel is solved, service life is long, and easy to process, repair rate is low.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of novel welding structure that skirt is connect with end socket, it includes end socket and skirt, and built-up welding forms heap on end socket
Layer, overlay cladding include overlay cladding fillet, overlay cladding outer circle and overlay cladding groove, and the weld seam between overlay cladding groove and skirt is
Fillet.
Further, pass through solder design between overlay cladding and skirt.
The utility model has the advantages that
This practical new connection by skirt and end socket is improved to complete overlaying structure from conventional welding structure, devises complete
New welding node, overlaying structure after built-up welding, then are added with the machine of routine using tooling built-up welding on designed end socket
Work method presses figure processing fillet, and last skirt and overlay cladding weld, it is therefore prevented that stress concentration, welding deformation avoid end socket mother
The damage of material, success rate is higher, is simple and efficient connection procedure, protects base material, improves processing progress；The welding structure is especially
It is applicable in skirt and end socket junction in fatigue vessel and needs equipment with rounded corners.
Detailed description of the invention
Fig. 1 is the welding structure schematic diagram of skirt Yu end socket junction routine；
Fig. 2 is the utility model skirt and end socket built-up welding schematic diagram；
Fig. 3 is that the utility model skirt and end socket weld schematic diagram；
Fig. 4 is the utility model skirt and the novel welding structure schematic diagram in end socket junction；
In figure: 1- end socket, 2- skirt, 3- weld seam, 4- overlay cladding, 41- overlay cladding fillet, 42- overlay cladding outer circle, 43- heap
Layer groove.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
The novel welding structure that a kind of skirt of the utility model is connect with end socket, as shown in Fig. 2, it includes end socket 1 and skirt
Seat 2, built-up welding forms overlay cladding 4 on end socket 1；As shown in figure 3, overlay cladding 4 includes overlay cladding fillet 41,42 and of overlay cladding outer circle
Overlay cladding groove 43；As shown in figure 4, being connected between overlay cladding 4 and skirt 2 by fillet weld seam 3.
The process of the utility model: the tooling that the welding structure is completed to need includes internal bracing ring (to prevent
1 base material of end socket deforms when built-up welding), recruitment region built-up welding as defined in the end socket 1, built-up welding at overlay cladding 4 shape, through examining
It tests after qualification and overlay cladding fillet 41, overlay cladding outer circle 42 and overlay cladding is processed to overlay cladding 4 by Fig. 3 with conventional machine-tooled method
Groove 43 welds convenient for skirt 2 and overlay cladding groove 5, then processes 3 fillet of weld seam by Fig. 4, guarantees rounding off, last skirt 2
Weld together with overlay cladding 4.The welding structure makes adjustment original assembling sequence and welding method, is fatigue vessel
The processing of fillet provides reliable method at end socket 1 and 2 attachment weld 3 of skirt.
According to practice test, the utility model in practice can be to avoid the stress collection at the Skirt weld of fatigue vessel
In, easy to operate efficiently not have surface damage using 3 fillet of weld seam that tooling is processed, installation accuracy is high, will not damage end socket mother
Material.The fatigue vessel especially small to diameter, skirt is high overcomes the difficulty of personnel's operation, the manufacture of equipment has been effectively ensured
Quality and processing progress.
The structure can reuse, save the cost the Fatigue equipment of different-diameter with retrofit application.
Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model
On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists
Within the protection scope of the utility model.
