Description
Technical field
The present invention relates to a kind of tube sheet corner joint auxiliary welding device and welding method, belong to Tube-sheet Welding
Technical field.
Background technology
For the middle thick sheet metal welding that thickness is 10mm 25mm, no matter it is banjo fixing butt jointing or T
Type joint, many employing K-type groove weldings, to reach the purpose of welding by both sides double-faced forming, especially tube sheet pair
The K-type weld seam connect, by the way of using frock or laminated metal sheet compression, can be easier to reduce its deformation,
Its welding manner has the multiple welding method such as submerged-arc welding, MAG weldering (metal active gas welding),
But the K-type groove welding method for tube sheet corner connection did not the most relate to.
The difficult point of the K-type weld seam of tube sheet corner connection is welding deformation and internal flaw, vertical particularly with having
Degree and the parts of planarity requirements, more should control welding deformation.Cause the main cause of welding deformation
Being that the heat input in welding process is uneven causes welding residual stress.Affect welding residual stress and distortion
Because have 2 points:
One is weld seam and the scope of non-uniform heat flux and degree about, i.e. produces scope and the journey of thermal deformation
Degree；
Two is the rigidity of weldment itself and the degree restrained by surrounding, i.e. stops weld seam and heating about
The degree of produced thermal deformation.
Owing to this type of weld seam is critical welding seams, postwelding needs to carry out magnetic powder inspection and ultrasonic examination, holds
Easily find internal containing defects such as pore, crackle, slag inclusion, position fusions, give to reprocess and make troubles, impact
Welding part quality stability, the main cause that these defects produce has: weld preheating temperature is improper,
Before weldering, polishing cleaning is not clean, and interlayer temperature controls not, and welding parameter is improper.
Chinese patent application CN102513713A discloses a kind of stainless steel clad metal plate pressing pressure container
Housing and plug-in type rustless steel connect the welding method of metal tube, and it comprises the steps:

Pore, is processed into K-type or a groove of single V-type by metal tube hole wall；
B), on a groove face with high chromium nickel stainless steel welding rod built-up welding certain thickness transition sealing coat,
Form secondary groove；
C), the stainless steel clad metal plate pressing pressure container casing of heap postwelding is carried out hidden lino removal；
D), weld with the stainless steel electrode of same material according to the material of the rustless steel cladding on clad metal sheet
Rustless steel connects the corner joint of metal tube and stainless steel clad metal sheetpile interpass.Due to first at rustless steel
With high chromium-nickel electrode built-up welding certain thickness transition sealing coat on groove of clad metal sheet basic unit side,
Then weld corner joint with stainless steel electrode, be rustless steel composition by carbon steel or low alloy steel composition transition,
The transition that plastic property of weld bead is ascending, it is to avoid the generation of crackle, serviceability is reliable.
But this kind of welding connects the weldering between metal tube just for dissimilar steel or Stainless Steel Shell and rustless steel
Connect, built-up welding transition deposition sealing coat in the K-type the most also offered in Stainless Steel Shell or double V-groove,
Carry out the welding of tube sheet again, owing to adding transition zone, cause Stress non-homogeneity, easily crack,
Must eliminate welding residual stress by heat treatment, construction technology difficulty is bigger, it is often more important that cannot be thorough
The hidden danger that welding dissimilar materials cracks is eradicated at the end, is only applicable to the relatively thin housing of hickness of metal plate and connects gold
Belong to the welding of pipe, to the Tube-sheet Welding of the middle thick sheet metal carbon steel material of 10 25mm inapplicable.
Summary of the invention
For realizing the K-type groove welding of tube sheet corner connection, and (emphasis is protected to have good weld appearance effect
Demonstrate,prove metal pipe and the perpendicularity of metallic plate and metal pipe end and the flatness of metal plank) and internal
Quality (flawless, pore, slag inclusion, lack of penetration, incomplete fusion), it is desirable to provide a kind of tube sheet
Corner joint auxiliary welding device and welding method, the problem that this welding method first has to solve is how to control
In system, the tube sheet corner joint K-type groove welding deformation of thick sheet metal thickness, becomes such that it is able to control welding

The bottoming welding of inboard root welding bead, after making root pass penetration, part weld metal passes through groove front,
Complete bottoming welding；
8), after bottoming welding, treat that temperature is down to 50 DEG C about 100 DEG C, the oxide skin on trimming surface,
After splashing, then being filled with the welding of layer, when being welded to groove depth 2/3 4/5, turn-over removes process bar,
And carry out back chipping by lathe external side groove root；
9), after back chipping completes, at external side slope mouth, weld seam and periphery carry out being preheated to 150 200 DEG C, then use
MAG weldering carries out outside multi-layer multi-pass welding, until outer side weld completely fills out, then is soldered into MAG
The welding of 1/5 1/3 degree of depth of remaining inside.
The operation principle of the present invention:
It is welded to the 2/3 4/5 of groove depth inside this elder generation, then the turn-over outer side weld of welding is to completely filling out,
The method completing remaining inside welding again, plays following effect:
(1) welding deformation of inside lateral bend can be produced during weld joint on inner side welding, can produce during the welding of outside
The welding deformation bent laterally, both cancel out each other；
(2) weld joint on inner side is welded to the 2/3 4/5 of groove depth, and outer side weld bottoming, filling, capping
Welding is once fully completed, and reason is that weld joint on inner side first welds, and the amount of contraction caused during welding is maximum, after
Xu Zhu successively decreases in road, and only outside welding bead is more could offset the stress deformation produced when weld joint on inner side welds；
(3) the most easy and simple to handle, thick sheet metal and metal circular tube in being connected by homemade 2 process bar,
Constrain mutual welding deformation, decrease welding turn-over number of times, reduce labor intensity, improve
Work efficiency, it is most important that need not welding tool setup, can well control welding deformation,
Weldquality is high, it is adaptable to the welding of the field likes such as track traffic.
