Description
Technical field
The present invention relates to multiple material forming frock processing technique field, especially a kind of large-scale composite material forming frock type
The welding method of plate.
Background technique
Welded composite molding tooling is divided into two parts of frame and template by structure, and frame match plate plays
Support and the effect for guaranteeing tooling integral strength, the effect of template are guaranteed compound for the shape of forming composite product
The formed precision of material product；
Needs are formed because composite products produce special production, it is necessary to assure template is airtight during forming parts
Property and thermal uniformity；To guarantee that ultra-large type answers the required precision of material forming frock template, template must be to type after sheet-metal formed
Plate carries out NC milling；Since large size answers the limitation of material forming frock part shape, sheet-metal formed technique and material specification,
Match plate is needed to carry out piecemeal molding and welding；For the thermally conductive uniformity of tooling during guarantee formed product it may first have to guarantee
The precision controlling of the formed precision of template and positioning after molding and welding deformation；Meanwhile also ensuring template in shaped article
The thermally conductive uniformity of process；Template positioning after molding is positioned using outling of truss, again because by frame effect type after frame positioning
Plate can only carry out single-sided welding；Match plate is also needed to carry out numerical control milling after the completion of welding as described above, after guarantee welding milling still
The first purpose that must assure that with air-tightness requirement and the present invention.
Summary of the invention
The object of the present invention is to provide the airtight welding sides of a kind of large-scale multiple material forming frock template single side, overlong welded seam
Method, this method can be adapted for the airtight welding that various welding structures answer the template single side overlong welded seam of material tooling, post welding distortion
Measure small, welding quality height inside and outside welding position.
To achieve the above objectives, the present invention, which adopts the following technical scheme that, is achieved:
A kind of large-scale composite material forming frock template welding method is welded using Multilayer single sequence, and welding number of plies n >=
4, first layer is TIG weldering, and the second layer, third layer are argon arc welding, the 4th layer and the above are gas shield weldings；The second layer, third layer
Segmentation argon arc welding is taken, along groove length direction segmented welding, wherein third layer argon arc welding opposite joint position and second layer opposite joint position
It sets and is staggered；4th layer and the above gas shield welding are welded using striping order, are in a good mood from two side of groove into groove in groove width direction
Sequence welding uses segmented welding in groove length direction.When segmented welding, first time segmented welding temperature is down to 200 DEG C or less
When, carry out second welding until overlap span is filled up, when multilayer segmented welding, upper one layer of opposite joint position and next layer of opposite joint
Position is staggered.
The application is described in further detail with reference to the accompanying drawings and embodiments.
Detailed description of the invention
Fig. 1 lower layer segmented welding schematic diagram
The upper layer Fig. 2 segmented welding schematic diagram
The 4th layer of sequence described above of Fig. 3 welds schematic diagram
Fig. 4 welding groove schematic diagram
Explanation: 1, template is numbered in figure；2, opposite joint position
Specific embodiment
As shown in Figure 1-3, being welded when a kind of large-scale composite material forming frock template 1 welds using Multilayer single sequence
It connects, welds number of plies n >=4, first layer is that TIG is welded, and the second layer, third layer are argon arc welding, the 4th layer and the above are gas shield weldings；It is described
The second layer, third layer take segmentation argon arc welding, along groove length direction segmented welding, wherein third layer argon arc welding opposite joint position 2
It is staggered with second layer opposite joint position 2；4th layer and the above gas shield welding are welded using striping order, in groove width direction from groove two
Lateral groove center sequence is welded, and uses segmented welding in groove length direction.When segmented welding, first time segmented welding temperature
When being down to 200 DEG C or less, second welding is carried out until overlap span is filled up, when multilayer segmented welding, upper one layer of opposite joint position
2 are set to be staggered with next layer of opposite joint position 2.
Welding groove as shown in Figure 4 is welding (t-2) × 60 °, and t is template thickness, and 2mm root face is first is that guaranteeing welding
When be not easy to penetrate, guarantee molten bath it is complete；Second is that A is deformed to because of frame entirety caused by welding contraction in order to prevent；Weld slope
60 ° of bicker degree, first is that guaranteeing there is sufficient gas flow space when welding；Second is that guaranteeing that manual welding is easy to operate；Weld slope
The thinking of 60 ° of bicker degree designs is that bevel angle is designed into minimum under the basis for guaranteeing both the above condition, mainly anti-
The only B buckling deformation that molten bath is generated by condensation in because of welding process；
Welding Process Design:
Welding first layer mainly has both sides welding requirements using TIG weldering: first is that the melting welding of same material can be well
Guarantee air-tightness, will not unevenly generate fire check because of the difference and heat input of material；Second is that being second layer argon arc welding molten bath
Molding, specification lay a solid foundation；
As shown in Figs. 1-2, the second layer, third layer are divided into and weld twice, to weld for the first time using segmentation argon arc welding
When temperature is down to 200 DEG C or less, carries out second and weld；Mainly prevent C as shown in Figure 4 to warpage using progressive welding method
Deformation；
4th layer and four layers or more using segmentation gas shield welding, as shown in Fig. 3 number order, in groove width direction from slope
It is welded to groove center sequence two sides of mouth；In length direction using segmentation weldering as second and third layer；Using such B to C to
Separating welding method mainly prevents B, C as shown in Figure 4 to buckling deformation.
