Abstract
The present invention relates to a kind of 120mm slabs and 24mm plate welding deformation controlling method, it is characterised in that: specific control method is as follows: S1: the setting of top plate I-steel；S2: the setting of bottom plate I-steel；By being spaced setting I-steel on box beam top plate and box beam plate outer surface in the present invention, the interruption on I-steel and box beam surface is welded and is arranged alternately on the top of box beam, bottom plate, to increase the rigidity of bottom plate free end side, the deformation of welding process insole board free end is effectively reduced；Since partition has sequencing in the welding process, box beam top plate and box beam bottom slab stress situation are inconsistent, therefore the I-steel on box beam top plate and bottom plate uses different welding manners, welding manner needed for guard box back plate and base plate strength.
Description
Technical field
The present invention relates to plate welding shape control field more particularly to a kind of 120mm slabs and 24mm plate welding deformation
Control method.
Background technique
Pressure-bearing partition is all made of the biggish steel plate of thickness at large size steel box-girder toughened internal stress at present, and existing example has reached
120mm is thick, and the steel box-girder top plate and bottom plate thickness being connected with super thick pressure-bearing partition is generally the relatively thin steel of 24mm or so
Plate, and push up, bottom plate free end length it is longer, about 1000mm or so.
Consider easily to occur when box beam top, bottom plate and super thick pressure-bearing partition are welded it is severely deformed, except by controlling each welding
Parameter includes that voltage, electric current, weldering speed, welding bead quantity etc. are outer, it is also necessary to provide a kind of more effective control for reducing welding deformation
Method, to reduce the correction workload after welding deformation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of 120mm slab and 24mm plate welding deformation controlling method, energy
It enough reduces when box beam top, bottom plate and super thick pressure-bearing partition weld and severely deformed problem easily occurs.
In order to solve the above technical problems, the technical solution of the present invention is as follows: a kind of 120mm slab and the welding deformation control of 24mm plate
Method processed, innovative point are: specific control method is as follows:
S1: the setting of top plate I-steel: in the cover top surface of pressure-bearing partition and box beam top plate junction, by length direction spacing
500mm~800mm, by breadth direction 150mm~200mm arrange long 600mm I-steel several, and every I-steel and case
The interruption welding of back plate, I-steel are orthogonal with diaphragm plate；
S2: the setting of bottom plate I-steel: to the lower surface of base plate of pressure-bearing partition and box beam back plate connections, by between length direction
Away from 500mm~800mm, by breadth direction 150mm~200mm arrange long 600mm I-steel several, and every I-steel with
The interruption welding of box beam bottom plate, I-steel are orthogonal with diaphragm plate；Bottom plate I-steel is in be arranged alternately with top plate I-steel.
Further, the I-steel and the interruption welding of box beam top plate and bottom plate use CO2Gas shielded welding, CO2Gas
Purity is not less than 99.5%, should access shield gas flow rate meter in gas circuit when welding.
The present invention has the advantages that
1) by being spaced setting I-steel, I-steel and box beam surface on box beam top plate and box beam plate outer surface in the present invention
Interruption welding and be arranged alternately on the top of box beam, bottom plate, to increase the rigidity of bottom plate free end side, effectively reduce welding
The deformation of process insole board free end；Because there is sequencing, box beam top plate and box beam bottom slab stress in the welding process in partition
Situation is inconsistent, therefore the I-steel on box beam top plate and bottom plate uses different welding manners, guard box back plate and bottom
Welding manner needed for plate intensity.
Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
A kind of 120mm slab and 24mm plate welding deformation controlling method, specific control method are as follows:
S1: the setting of top plate I-steel: in the cover top surface of pressure-bearing partition and box beam top plate junction, by length direction spacing
500mm~800mm, by breadth direction 150mm~200mm arrange long 600mm I-steel several, and every I-steel and case
The interruption welding of back plate, I-steel are orthogonal with diaphragm plate；
S2: the setting of bottom plate I-steel: to the lower surface of base plate of pressure-bearing partition and box beam back plate connections, by between length direction
Away from 500mm~800mm, by breadth direction 150mm~200mm arrange long 600mm I-steel several, and every I-steel with
The interruption welding of box beam bottom plate, I-steel are orthogonal with diaphragm plate；Bottom plate I-steel is in be arranged alternately with top plate I-steel.
I-steel and the interruption welding of box beam top plate and bottom plate use CO2Gas shielded welding, CO2Gas purity is not less than
99.5%, shield gas flow rate meter should be accessed in gas circuit when welding.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
It is merely illustrated the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also has
Various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention
It is defined by the appending claims and its equivalent thereof.
