Abstract
The invention discloses a multi-gun narrow-gap hot wire TIG welding method and an annular workpiece. Multiple welding guns are arranged at the front end of a welding arm and linearly and continuously arranged in the welding direction. During welding, the multiple welding guns conduct welding at the same time, the welding gun located at the front end forms a weld bead on the first layer, and the welding guns located on the back side conduct welding on the weld bead on the first layer. Compared with a narrow-gap submerged-arc welding method, the multi-gun narrow-gap hot wire TIG welding method and the annular workpiece have the advantages that a bevel is narrow, the quantity of cladding metal is reduced, and cost is reduced. The multi-gun narrow-gap hot wire TIG welding method and the annular workpiece overcome the defects that in the heavy pressure vessel assembly welding field, by the adoption of traditional methods, a weld joint bevel is wide, one welding gun welding is adopted, and the automation degree is low and inherit the advantage of high weld joint quality of a hot wire TIG welding method.

Background technology
At present, welded for heavy vessel low-alloy steel girth joint group, it is main in manufacturing at present to use narrow gap submerged arc
Welding method, although submerged-arc welding efficiency is higher, but have that welding surroundings are poor, automaticity is low, higher to welder's skill set requirements
The shortcomings of.
The content of the invention
According to technical problem set forth above, and a kind of multiple gun narrow-clearance heating wire TIG welding method and annular workpieces are provided,
For solving the existing welding method for being applied to annular workpieces, welding surroundings are poor, automaticity is low, to welder's skill set requirements
Higher the shortcomings of.The technological means that the present invention is used is as follows：
A kind of multiple gun narrow-clearance heating wire TIG welding method, welding arm front end be provided with it is many welding gun, it is many described welding gun
Continuously arranged along welding direction wire, many that the welding gun is welded simultaneously after the starting the arc, front end welding gun welds to form first floor welding bead,
The welding gun welding bead of rear side press against front side welding gun pass weld, realize that single multilayer is welded, every that welding gun is welded one layer.
During as preferred weld, welding gun is arranged at downhand welding position position, remaining welding gun by many of the linear alignment by the first of welding gun
It is arranged at uphill welding position.
As preferably when the weldering of girth joint group is carried out, many spacing between welding gun are adjusted according to shell ring size, every
The soldering angle of welding gun can be adjusted；And it is many that welding gun can integrally be unified to carry out automatically controlling operation, and every
Welding gun is individually controlled operation.
As preferably when existing defects in welding process, or because other failures, in welding process wherein one rifle
When stopping welding, all welding guns stop welding；That of stopping welding individually lifts welding gun, after recovering normal, all welderings
Rifle proceeds welding simultaneously.
Welding gun can be realized the welding manner that individual layer single track, tungsten electrode shake as preferably every, it is ensured that side wall is merged.
During preferred weld, high-definition camera captured in real-time and display conditions at the arc and figuration of bead feelings are set
Condition.
As the tracking of decision design arc voltage and automatic control system, multiple gun is carried out while welding Collaborative Control, automatic amendment
Welding torch position.
As preferred welding gun continuously four are placed with along welding direction wire.
A kind of annular workpieces being welded using above-mentioned multiple gun narrow-clearance heating wire TIG welding method.
Compared with prior art, multiple gun narrow-clearance heating wire TIG welding method of the present invention and annular workpieces, many
Described welding gun is continuously arranged along welding direction wire, and many that the welding gun is welded simultaneously after the starting the arc, front end welding gun welds to be formed
First floor welding bead, the welding gun welding bead of rear side press against front side welding gun pass weld；Compared to narrow-clearance submerged arc welding method, groove is narrow, subtracts
Lack deposited metals amount, reduce cost；Multiple gun narrow-clearance heating wire TIG welding method of the present invention and annular workpieces, gram
The traditional weld groove in heavy pressure vessel group weldering field wide, single rifle welding, the low problem of automaticity have been taken, heat has been inherited
Silk TIG weld method weldquality advantage high.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the present invention four welding gun arrangement structural representation.
Specific embodiment
As shown in figure 1, a kind of multiple gun narrow-clearance heating wire TIG welding method, welding arm front end be provided with it is many welding gun, many
Described welding gun is continuously arranged along welding direction wire, and welding gun is preferably wire and is continuously placed with four along welding direction.The starting the arc
Afterwards, many that the welding gun is welded simultaneously, front end welding gun welds to form first floor welding bead, and the welding gun welding bead of rear side press against front side welding gun weldering
Weld in road.Welding process is every to be responsible for one layer of welding welding gun, realizes that four layers of welding bead are welded simultaneously.
During welding, welding gun is arranged at downhand welding position position by many of the linear alignment by the first of welding gun, and remaining welding gun is arranged at
Slope welding position is put.It is every that narrow clearance welding gun is possessed transferred arc function, the frequent starting the arc is avoided during lane-change.
When the weldering of girth joint group is carried out, many spacing between welding gun are adjusted according to shell ring size, every weldering welding gun
Connecing angle can be adjusted；And it is many that welding gun can integrally be unified to carry out automatically controlling operation and every that welding gun is independent
It is controlled operation.
Every welding manner that welding gun can be realized individual layer single track, tungsten electrode shake, it is ensured that side wall is merged.In welding process,
High-definition camera captured in real-time and display conditions at the arc and figuration of bead situation are set.Design arc voltage is tracked and automatically controlled and is
System, carries out multiple gun while welding Collaborative Control, and welding torch position is corrected automatically.
When existing defects in welding process, or because other failures, in welding process wherein one stops rifle welding
When, all welding guns stop welding；That for stopping welding individually lifting welding gun, after recovering normal, all welding guns at the same after
It is continuous to be welded.
In view of single the low shortcoming of rifle narrow gap TIG weld efficiency, the present invention is pioneering to propose " pressure road formula " multiple gun narrow gap
Heating wire TIG welding method, it is low that the technology overcomes single rifle TIG weld efficiency while ensure that the advantage of original TIG weld
Problem, the method be mainly used in thick-walled vessel deep groove welding.
Narrow-clearance heating wire TIG is the welding method of a kind of low consumption, high-quality, and its welding process is controllable, it is easy to accomplish digitlization,
Intellectuality welding.Have that few deposited metal, welding quality stable, welding deformation be small, working environment relative to narrow-clearance submerged arc welding
Superior the advantages of.Therefore, using multiple gun narrow-clearance heating wire TIG solder technology, and it is applied to the weldering of heavy vessel product girth joint
Connect in manufacturing, with suitable realistic meaning.
A kind of annular workpieces being welded using above-mentioned multiple gun narrow-clearance heating wire TIG welding method.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technology according to the present invention scheme and its
