Abstract
The invention provides a multiple-row pipe for laser protection gas welding. The multiple-row pipe for the laser protection gas welding can jet protection gas in a wide range, enable gas flow to be stable and guarantee welding quality. The multiple-row pipe for the laser protection gas welding is characterized by comprising jet pipes which are arranged in parallel and placed on a support, cone-shaped jet nozzles are connected below the jet pipes, and the diameter sizes of the cone-shaped jet nozzles are different.
Description
Technical field
The present invention relates to the laser welding technology field, be specially laser radiation gas welding multi coil.
Background technology
The desirable thermal source that laser is considered to weld, laser weld is one of most important application of laser technology, it is that the light beam that utilizes the polariscope reflector laser to produce makes it concentrate on the light beam that produces huge energy in the focusing arrangement, the process technology that the characteristic of laser beam and matter interaction is welded material (comprising metal and nonmetal).Laser weld has heating and concentrates, the heat input is few, be out of shape little, speed of welding fast (can reach several meters to tens meters of per minutes), the welding depth-to-width ratio is large, quality is high, not only is suitable for conventional material, also is particularly suitable for refractory metal, it is inflammable to be heated near the workpiece that thermalloy, dissimilar metal, volume and thickness difference that titanium alloy thermophysical property difference is large are large and the weld seam, is heated and easily splits and the explosive member that is heated.Weld seam is attractive in appearance, beautiful, and weld seam can be strong with mother metal etc. in many situations.And laser beam can transmit by optical fiber, therefore can save complicated light beam transfer system, is applicable to flexible manufacturing system or long-range processing.Laser weld both can be spot welding, also continuously seam weldering.
Usually can lead to protection gas when carrying out laser weld protects; and existing protection gas blowout pipe can only carry out jet from a side spray gas; and too large or too little other gases that all can not in time take away in the atmosphere of shielding gas flow speed of ejection; weldment is oxidized in the cooling, and welding quality impacts.
Summary of the invention
For the problems referred to above, the invention provides laser radiation gas welding multi coil, its protection gas of can jetting on a large scale, and so that air-flow is steady, guaranteed welding quality.
The technical solution adopted in the present invention is: it is characterized in that: it comprises jet pipe, and described jet pipe be arranged in parallel, and is installed on support, and described jet pipe below connects conical nozzle, and the caliber size of described conical nozzle is inconsistent.
It is further characterized in that: be provided with steel wire in the described conic nozzle.
After adopting design of the present invention; the design of a plurality of jet pipes has increased the scope of winding-up protection gas; so that protection gas can cover pad more comprehensively; the design of the nozzle of different sizes is so that the speed of winding-up protection gas has multiple choices; can regulate according to obstructed situation; the protection gas that the steel wire that designs in nozzle so that jet is more steady, has improved welding quality.
Description of drawings
Fig. 1 is the structural representation of jet pipe of the present invention.
Fig. 2 is the structural representation of the nozzle of conical nozzle connection of the present invention.
The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
See Fig. 1 and Fig. 2, it comprises that among several jet pipes 1(figure be 4 the present invention), jet pipe 1 be arranged in parallel and is installed on support 2, jet pipe 1 below is connected with conical nozzle 3, the bore of conical nozzle 3 is arranged to arrange from big to small, and is different, is provided with steel wire 4 in the conic nozzle 3.
The design of a plurality of jet pipes 1 has increased the scope of winding-up protection gas; so that protection gas can cover pad more comprehensively; the design of the nozzle of different sizes is so that the speed of winding-up protection gas has multiple choices; can select different nozzles according to obstructed situation; the protection gas that the steel wire 4 that designs in nozzle so that jet is more steady, has improved welding quality.
Claims (2)
1. laser radiation gas welding multi coil, it is characterized in that: it comprises jet pipe, and described jet pipe be arranged in parallel, and is installed on support, and described jet pipe below connects conical nozzle, and the caliber size of described conical nozzle is inconsistent.
