Abstract
The utility model discloses a kind of carbon dioxide gas arc welding welding gun structure; comprise ignition tip (2), nozzle (3) and wire feeder; described wire feeder conveying welding wire (1); described nozzle (3) comprises link and working end, and the cross sectional shape of described working end is kidney-shaped.Adopt technique scheme; this carbon dioxide gas arc welding welding gun structure provided by the utility model; be large slab be U-shaped for workpiece or the root of J type groove and bottom; the welding gun of this structure can be used to weld, not only decrease the labour intensity of workman, improve operating efficiency; also ensure that welding quality simultaneously; by checking, weld seam 100% is checked by ultrasonic examination, and disposable flaw detection qualification rate is more than 95%.
Description
Technical field
The utility model belongs to iron and steel production and processing technical field, and more specifically, the utility model relates to a kind of carbon dioxide gas arc welding welding gun structure.
Background technology
In steel production enterprise; 70% bevel for welding that sometimes can run into crucial workpiece is U-shaped or J type; its groove type width is narrow; the narrowest place of root width only has 15mm; for the bevel for welding of steel plate thickness more than 80mm; the root of workpiece and bottom cannot adopt carbon dioxide gas arc welding to implement welding, also cannot ensure welding quality simultaneously.Current carbon dioxide arc welding is semiautomatic welding; the diameter of welding wire is 1.2mm; the nozzle od of welding gun is minimum is 20mm; the maximum extension elongation of welding wire is about 15mm; in order to ensure welding quality; if increase the extension elongation of welding wire; easily there is the fusing of the overheated section of forming in welding wire; splash serious, welding process is unstable, and gas shield effect is also bad; weld seam easily produces pore; simultaneously the root of workpiece and bottom can only adopt manual electric arc welding weld, but operating efficiency lowly, and cost is high and labour intensity is large.
Utility model content
Problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of and increases work efficiency, reduce labour intensity and ensure the carbon dioxide gas arc welding welding gun structure of welding quality.
To achieve these goals, the technical scheme that the utility model is taked is:
This carbon dioxide gas arc welding welding gun structure provided by the utility model, comprises ignition tip, nozzle and wire feeder, and described wire feeder conveying welding wire, described nozzle comprises link and working end, and the cross sectional shape of described working end is kidney-shaped.
The model of described welding wire is ER50-6, and diameter is 1.2 millimeters.
The height of described nozzle is 15 millimeters to 20 millimeters.
Adopt technique scheme; this carbon dioxide gas arc welding welding gun structure provided by the utility model; be large slab be U-shaped for workpiece or the root of J type groove and bottom; the welding gun of this structure can be used to weld, not only decrease the labour intensity of workman, improve operating efficiency; also ensure that welding quality simultaneously; by checking, weld seam 100% is checked by ultrasonic examination, and disposable flaw detection qualification rate is more than 95%.

Detailed description of the invention
As shown in Figures 1 to 4; this carbon dioxide gas arc welding welding gun structure provided by the utility model, comprises ignition tip 2, nozzle 3 and wire feeder, wire feeder conveying welding wire 1; nozzle 3 comprises link and working end, it is characterized in that: the cross sectional shape of working end is kidney-shaped.
Adopt technique scheme; this carbon dioxide gas arc welding welding gun structure; for root and bottom that workpiece 4 is the U-shaped or J type groove of large slab; the cross sectional shape of working end is kidney-shaped; reduce the appearance and size of nozzle 3 in groove 5 transverse direction; make welding gun can reach U-shaped or the root of J type groove 5 welds, also ensure that the welding quality of weld seam.
Groove 5 is entered for ignition tip 2 and nozzle 3 position during welding; ignition tip external diameter is 8mm; diameter is less; it is the strength member that welding gun completes conduction, transporting welding wire; during welding welding gun air-channel system by nozzle 2 inner chamber combing; the protection gas hood making welding gun spray laminar flow from nozzle 2 shrouds arc region, plays the effect of protection welding pool.
As shown in Figures 1 to 4, the model of welding wire 1 is ER50-6, and diameter is 1.2 millimeters
The height of nozzle 3 is 15 millimeters to 20 millimeters.
Adopt technique scheme; the height of torch neck 2 is 15 millimeters to 20 millimeters; this is that the protected effect of protective gas is best, and weld seam is not easy to produce pore, adopts DC reverse connection during welding; namely workpiece 4 connects the negative pole of power supply; welding gun connects the positive pole of power supply line, the carbon dioxide gas arc welding welding gun structure of this structure, by checking; weld seam 100% is checked by ultrasonic examination, and disposable flaw detection qualification rate is more than 95%.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
