Change and be provided with two carbon dioxide welding machine heads on the welding machine platform of carbon protection welding machine, connected on each carbon dioxide welding machine head
One carbon dioxide welding gun；When welding two weld seams on one of solder side, first of welding of first layer is first carried out, is adjusted
The position of whole two carbon dioxide welding guns causes both tips to be oppositely arranged, then welding wire is aligned into weld seam, two carbon dioxide
Welding gun is simultaneously and synchronously welded, and the fusing metal of weld seam will fully melt to ensure welding effect during welding；
S3：The second that two weld seams on one of solder side are carried out with first layer welds, and first adjusts two dioxies
The position for changing carbon welding gun causes two carbon dioxide welding gun phases eight to open, then welding wire is aligned into weld seam, and two carbon dioxide welding guns are same
When and synchronously welded, second weld seam will melt 3rd/2 to five/5ths of first of weld seam during welding；
S4：Second layer welding is carried out to two weld seams on one of solder side, first adjusts two carbon dioxide welding guns
Angle it is each perpendicular to Weld pipe mill position, then two carbon dioxide welding guns are improved into 8-12 ㎜ upwards, finally by welding wire
Alignment two carbon dioxide welding guns of weld seam simultaneously and synchronously weld to it；
S5：Box column is overturn to two weld seams welded after 180 ° on another solder side, successively using step S2, S3
And S4 welding method is welded；
S6：After two weld seam second layers on another solder side have welded, then with step S4 method it is carried out
Third layer is welded and the 4th layer of welding, until the weld seam integral solder on the face terminates；
S7：Box column is overturn to 180 ° again, two weld seams on one of solder side entered using step S4 method
Row third layer is welded and the 4th layer of welding, until the weld seam integral solder on the face terminates；
S8：By the box column air cooling 8-12h after welding, ultrasonic examination detection is carried out to weld, it is ensured that welding quality.
Preferably, the welding machine platform is fixed on driving dolly, and two carbon dioxide welding guns pass through welding gun insulating sheath point
It is not fixed on two clampers on walking dolly.
Preferably, the angle in step S2 between the tip extended line of two carbon dioxide welding guns is 90-120 °.
Preferably, the angle in step S3 between the afterbody extended line of two carbon dioxide welding guns is 90-120 °.
Preferably, in step S2, welded at welding wire alignment weld seam angle 2 ± 0.5 ㎜ on the upper side during welding.
Preferably, in step S3, welded at welding wire alignment weld seam angle 1.5 ± 0.3 ㎜ on the upper side during welding.
The present invention at least has following beneficial effect：
(1) welded when being welded, and welded using multilayer during present invention welding using double end shielded arc welding of automatic carbon dioxide
Connect, walking dolly can accomplish when welding two weld seams it is in the same direction, synchronous, with specification welding, therefore two on same solder side
Weld seam is heated evenly consistent, expansion as contraction time, can be very good to control welding deformation, will not especially be distorted change
Shape, save weld interval, also saved torsional deformation correction generation expense；
(2) quickly, welding process is simple to operate, largely reduces hand labor for automatic welding speed of the present invention
Intensity；And it can work continuously, hence it is evident that improve welding efficiency, there is especially good quality and benefits；It is and several inside weld seam
Without exceeded weld defect, appearance of weld is highly stable, and weld seam width is consistent, and weld seam shows fine and closely woven scalelike mark, face of weld
Very smooth, weld reinforcement is consistent, and ultrasonic inspection qualification rate reaches percentage more than 98；
(3) jig, carbon dioxide welding machine head are assembled together to be fixed on walking dolly and are connected again with control device
Automatic welding device is formed, suitable for being welded with various spaces, is relatively flexibly used；Take rear walking dolly and manual titanium dioxide apart
Carbon gas shielded arc welding is single, can be worked independently in oneself scope, and existing automatic welding is typically all to fix at present
Equipment, infusion of financial resources is bigger, suitable for welding limited space system, can not all be worked independently after taking apart.
In order to realize above-mentioned and related purpose, one or more aspects of the invention include will be explained in below especially
The feature pointed out.Some illustrative aspects of the present invention are described in detail in following explanation and accompanying drawing.However, these aspects refer to
What is shown is only some modes in the various modes for can be used the principle of the present invention.In addition, it is contemplated that including it is all this
