Technical background
It is a kind of of welding that gas shielded arc welding connects, and is divided into non-consumable gas shielded arc welding (GTAW), gas metal-arc welding (GMAW) usually again.Common non-melt pole inert gas-shielded arc welding (TIG) characteristics are to obtain high-quality welding point; be widely used in the welding production of titanium alloy, aluminium alloy, stainless steel and high temperature alloy etc.; but when welding, arc energy do not concentrate, and caused single track can weld that thickness is little, welding efficiency is low and postwelding crystal grain has the phenomenon of growing up.For the bigger weldment of thickness, need the preceding bevel of weldering or carry out multi-pass welding, add a lot of additional process and extra auxiliary equipment.Therefore general T IG weldering at present is used for the bottoming welding of thin part or multilayer welding more.
And the weldering of consumable electrode gas comprises welding (MIG), metal active gas welding (MAG) and carbon dioxide gas arc welding (CO
2Weldering).Be commonly referred to the gas shield metal arc welding, be called for short " GMA " welding.Common GMA welding adopts the metal welding wire as electrode.In most cases welding wire is to send in some way, forms electric arc and weld between welding wire and mother metal.GMA welding production efficiency is higher, welding cost is lower, but the droplet transfer during the GMA welding is wayward, and splashing amount is bigger, is difficult to guarantee high-quality welding quality during welding.The GMA weldering is widely used in the welding production of aluminium alloy, structural steel, low-alloy steel etc.For the welding of medium and above thickness material, adopt TIG weldering bottoming, GMA weldering to fill and capping usually.
Summary of the invention
The object of the present invention is to provide a kind of gas shield welder that can realize the complex method that the process stabilization under the common welding condition, quality of weld seam molding height, welding efficiency significantly promote, just a kind of arc welding method and device thereof that adopts additional acoustic pressure mode.
The object of the present invention is achieved like this: adopt the arc-welding set of additional acoustic pressure mode, be made up of acoustic transducer 2, acoustics luffing bar 3, protection gas jets 4, welding electrode folder 5, acoustics generation source 9 and the source of welding current 8.Acoustic transducer 2 joins with acoustics luffing bar 3; Welding electrode folder 5 is combined closely with acoustics luffing bar 3; Non-melt electrode and metal molten electrode 1 form good electrical contact by acoustic transducer 2, acoustics luffing bar 3 with welding electrode folder 5; There is the position of enough acoustic sound pressure the end of protecting gas jets 4 that makes that protection gas jets 4 is fixed on acoustics luffing bar 3.
The present invention adopts the gas shield welder of complex method, and welding step is as follows:
1. by acoustics the acoustics signal of telecommunication that the source converts the 50Hz-220V common electrical to 100Hz-2MHz takes place.
2. acoustics generation source is by acoustic transducer, and the signal of telecommunication of acoustics frequency is converted into mechanical oscillation.

5. there is the position of enough acoustic sound pressure the end that makes the protection gas jets that will protect gas jets to be fixed on the luffing bar.
6. when welding, start electric arc, after waiting to stablize, restart acoustics the source takes place, transducer converts electrical energy into vibration, by the luffing bar acoustic vibration amplitude is amplified, and passes to electrode and protect gas jets.
The present invention used in non-melt pole pattern following time, had the high advantage of weld penetration, quality of weld seam molding that welding process is stable, improve single-run welding, can be implemented in the efficient welding under the common non-melt pole welding surroundings.
The present invention used in consumable electrode pattern following time; having welding efficiency significantly improves, can effectively control the sweating heat input quantity and pass through to change parameters such as acoustics frequency, protection gas jets position and welding and assembling height; change weld penetration, effectively control the solidification and crystallization state of deposite metal.
The present invention has realized the improvement to the traditional welding system, has good economic benefit and wide application market.To the influence of arc shape and electrode tip deposite metal, it is more reasonable to make that arc energy distributes through acoustic pressure, and Arc System stressed helps welding more and produce.Increased the fusion penetration of weld seam under the non-melt pole pattern, the hot input quantity when having controlled the droplet transfer under the consumable electrode pattern.The present invention compares with the traditional welding system, has increased weld penetration, has controlled hot input quantity, has optimized the welding point tissue morphology, has improved the combination property of joint.
Description of drawings
Fig. 1 is the principle schematic of apparatus of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment 1; in conjunction with Fig. 1; the signal of telecommunication that acoustics is taken place in the source is converted into mechanical oscillation by transducer; the mechanical oscillation amplitude of transducer is less; luffing bar by next stage is amplified to 10 μ m-150 μ m with it; again vibration is passed on the protection gas jets and electrode that is fixed on the luffing bar, as shown in Figure 1.Said apparatus can be that 100Hz works under the acoustic vibration of 2MHz in frequency, produces the acoustic vibration of corresponding frequencies on electrode.The input power of sound system can then, be welded according to the method for common gases protection weldering at 1W to regulating arbitrarily between the 3000W.After applying acoustic vibration, because protection gas jets and acoustic pressure that electrode produced can have certain compression to welding arc, so electric arc is adding man-hour to workpiece, it is more reasonable that welding energy is distributed, and improves the electric arc utilization rate when welding effectively.
The present invention with electric arc not only as the mechanism that produces heat, simultaneously with electric arc as the object that applies acoustic pressure, utilize the energy affect electric arc of acoustic sound pressure, improved the utilization ratio of arc energy.Be operated under the non-melt pole pattern, acoustic pressure has compression arc and then increases welding penetration.And be operated under the consumable electrode pattern, the metal that acoustic pressure has melted the consumable electrode end applies extra power, and then can control the droplet transfer situation under different current conditions effectively, in the hope of reaching when guaranteeing melting efficiency workpiece is had rational hot input quantity.So utilize the acoustic pressure that applies to change the form of electric arc, Energy distribution situation and joint microstructure form when improving welding improve the homogenization degree of composition and the mechanical property of joint.
The present invention adopts the arc welding of protection pneumoelectric can realize the welding production of most of metals such as non-ferrous metal, stainless steel and high temperature alloy; on the basis of traditional welding method; designed the tool heads of a cover special shape; make it both as welding gun; simultaneously be again the tool heads of acoustics emission, make common be welded on applied acoustic vibration after, arc shape is improved significantly; Energy distribution when making it to weld is more reasonable, and welding efficiency significantly improves.Electric arc straightness after the improvement is good, and is insensitive to the variation of arc length, and arc stability is good, and the hot input quantity of the weld seam of the unit depth hot input quantity of the unit of reaching deposite metal amount less reduces, and has effectively controlled the hot input quantity of efficient welding, and welding quality is good.Also have good controllability and modulability simultaneously.On the basis of common arc welding system, changed welding torch used when welding, by welding torch acoustic sound pressure is applied on the welding arc, improved the performance of welding arc.
