Description

Gas protection device for laser-arc hybrid welding and laser-arc hybrid welding machine
Technical field
The relevant compound soldering equipment of a kind of laser of the present invention particularly relates to a kind of gas protection device for laser-arc hybrid welding and has the laser-arc hybrid welding machine of this gas shield device.
Background technology
Laser weld as a kind of precision, efficiently, high energy beam welding method fast, obtained application more and more widely at aerospace field.But conventional laser weld also exists some problems and defective, and, assembly precision low such as utilization ratio of laser energy requires height, apparatus expensive etc.In order to address these problems, proposed several new laser welding technologies in the prior art: a kind of is many focal argon lasers solder technology, and this welding method can improve utilization ratio of laser energy, improves the stability of welding process, improve weldquality, can reduce requirement simultaneously assembly precision.Another kind is a compound welding technology, promptly adopts laser and other thermals source jointly as welding heat source, and this technology can effectively increase fusion penetration, raises the efficiency, and can also improve joint performance to a great extent, reduces equipment cost.The welding of laser-arc composite heat power supply is that physical property and the distinct two kinds of thermals source of energy transmission mechanism are combined with each other, and acts on same Working position simultaneously.The compound of laser and electric arc makes two kinds of thermals source both give full play to advantage separately, remedied the other side's deficiency again mutually, thereby formed a kind of thermal source of new high efficiency.
In above-mentioned hybrid Laser-Arc Welding, the effect of protective gas is all most important, in high power CO 2In the laser weld, the laser beam of high power density is radiated at test specimen when surface, and base metals is heated in the extremely short time, melts, evaporation and ionization.Form the surface that plasma at first is formed at test specimen by metal ion, protection gas ion, steam and electronics etc., high plasma vapour compression shock molten metal material forms aperture, finally forms penetration fustion welding.If power density continues to increase, plasma will leave surface of the work, form plasma shield, will hinder the carrying out of welding.Therefore must utilize the drift of protective gas control plasma, realize the protection of butt welded seam simultaneously.In TIG or MIG welding, protective gas directly influences the arc welding characteristic, decision welding procedure stability, appearance of weld and joint performance.Obviously, in the laser-electric arc composite welding process, protective gas has significant effects and important effect equally to technical process and appearance of weld, and its research has important theory and engineering significance.Therefore; when hybrid Laser-Arc Welding integrated design; the gas shield structure Design also will meet certain requirements; existing at present use protective gas protects the technology of welding normally in the plumb joint side protective gas conduit to be set; be used for to the weld seam injecting protective gas; the protection weld seam is avoided contacting with air; thereby guarantee the seam crossing welding performance; but this kind conduit is for forming certain thickness protection gas-bearing formation in the commissure; the protective gas flow velocity can not be too high, thereby can not effectively suppress the drift and the consequent laser shielding action of plasma.Therefore to improve on the basis of welding quality effectively controlling gas direction and flow velocity, designed rational gas shield structure.
In addition, for such as laser-TIG composite welding as a kind of novel welding method that combines two kinds of welding heat sources, both needed to consider for its control procedure that they made the welding parameter of time spent separately, also needed to consider that their parameter control after compound was as the distance of electric arc and laser action point etc. simultaneously.Therefore in laser-TIG composite welding head design process, must consider location parameter adjusting of thermal source alone and the relative position parameter regulatory function between two thermals source respectively.
The size of arc length is one of main factor that influences appearance of weld and arc energy density in the TIG welding process.In order to obtain uniform high quality welding joint, arc length must remain unchanged in whole welding process, yet because the out-of-flatness of surface of the work, the influence of factors such as the scaling loss of tungsten electrode, arc length can change, therefore in the welding gun design process, requirement can realize the position adjustment of electric arc arc length, has real-time independent electric arc arc length positions and adjusts function.In addition, all there is a heat source spacings D who obtains maximum fusion penetration in the laser composite welding.This just shows that the position parameter that best embodies this thermal source synergy is exactly the distance of electric arc and laser action point.Therefore in order to obtain uniform fusion penetration and good shaping surface, it is constant relatively that D must keep.But change, need in welding process, carry out real-time heat source spacings adjustment for this reason because the scaling loss of the surface height variation of workpiece and tungsten electrode must cause D to follow.Therefore in the welding gun design process, requirement can realize the adjustment of D, adjusts function to satisfy two real-time thermal source relative positions.
