The specific embodiment
Below in conjunction with drawings and Examples the base Welding Structure on a kind of pipeline of the present invention or the equipment is described in further detail, but not as the foundation of the present invention being done any restriction.
Embodiment.The welding method of base of the present invention and structure, as shown in Figure 1.Its method is to process a bevel for welding 4 on base 2 earlier, has an end of bevel for welding 4 and media Containers 1 (pipeline or equipment) to weld base 2, and weld seam 5 surfaces at bevel for welding 4 places are arcuation.Base 2 is processed a whole hole 6 of running through base and media Containers afterwards with media Containers 1 welding from base 2 tops, the bottom surface diameter Dd of bevel for welding 4 is less than the diameter Dz in whole hole 6.Base 2 tops process a bullport 3 coaxial with base earlier before welding or after the welding, bullport 3 can be a through hole; It also can be blind hole.The diameter Dy of bullport 3 is less than the bottom surface diameter Dd of bevel for welding 4 and the diameter Dz in whole hole 6.
The Welding Structure of the base of present embodiment, as shown in figures 1 and 3, the final figure of Fig. 1 present embodiment wherein, Fig. 3 is before the undressed whole hole 6.As seen from Figure 1, the Welding Structure of base comprises the base 2 that is welded on the media Containers 1; The base top is provided with a bullport 3 before the whole hole of processing; Coaxial with base 2, bullport 3 is through hole or blind hole.The diameter Dy of bullport 3 is less than the bottom surface diameter Dd of bevel for welding and the diameter Dz in whole hole.Base 2 bottoms are provided with bevel for welding 4, and the angle α on the cylindrical of bevel for welding 4 and media Containers 1 surface is 40～50 °.Base 2 and media Containers 1 are provided with the whole hole Dz that runs through base 2 and media Containers 1, and the bottom surface diameter Dd of bevel for welding 4 is less than the diameter Dz in whole hole.
During concrete enforcement, process base 2 earlier, base 2 as shown in Figure 2, at base 2 bottoms processing bevel for welding 4, the bottom surface of bevel for welding is circular, and diameter Dd can process a bullport 3 simultaneously at base 2 tops when processing base 2, bullport 3 can be that blind hole also can be a through hole, also can not process, but preferably process simultaneously, and it is best to be processed into blind hole, when the whole hole Dz of processing, can play good positioning action like this.The diameter Dy of bullport 3 is less than the bottom surface diameter Dd of bevel for welding and the diameter Dz in whole hole.When if bullport 3 is processed into through hole, the diameter Dy of bullport 3 should be less than the bottom surface diameter Dd of bevel for welding, and after not so bullport 3 processed, base had fallen owing to following bevel for welding place is processed, makes the base height diminish, and influences installation accuracy.After base 2 and media Containers 1 weld, will be along the whole hole 6 of bullport 3 processing, the diameter Dz in whole hole 6 should be greater than the diameter Dy of bullport 3, specific practice is to use the drill bit smaller than the diameter in whole hole 6 to bore down from bullport 3 earlier, the wall of media Containers 1 is drilled through together always, reaching machining accuracy by reaming and articulation hole then.Because the base diameter D of bevel for welding 4
DDiameter D less than whole hole 6
YSo when the whole hole 6 of processing, the scolder of bevel for welding 4 bottoms can be fallen clearly, is called back chipping and handles.In general, because bevel for welding 4 bottom gaps are less, scolder is difficult for heap enters, and is easy to generate bubble or crackle in welding.When carrying out 6 processing of whole hole, bevel for welding 4 bottom welding qualities can be gone wrong easily local one pulls out of hole, Here it is back chipping.Process at one time owing to final through hole 6 in addition, so whole hole 6 good concentricity on base 2 and the media Containers 1 are more convenient when connecting branch.During welding, the requirement of butt welded seam is a smooth surface, and it is circular-arc that face of weld should be, to reduce welding stress.
