Description
Technical field
The present invention relates to welding technology field, specifically is a kind of welding method for micro-plasma arc welding of pure titanium foil.
Background technology
Because the titanium material has special corrosion resistance and mechanical property, in industry plant equipment such as Aero-Space, chemical industry and medicine, obtained using widely.The maximum characteristics of titanium material are that specific strength is big, and the high and low temperature performance is good, all have the superior corrosion resistance energy in seawater and most of acid, alkali, salt medium.In industrial production, growing to the demand of pure titanium foil (the ultra-thin pure titanium plate of thickness below 0.1mm), therefore, it is more and more important that the welding of pure titanium foil also seems.
The welding of pure titanium foil and other metal material is compared, and following welding difficulty is arranged:
1, the special weldability of titanium.Titanium is a kind of reactive metal, under the high temperature, titanium easily and oxygen, nitrogen, hydrogen fast reaction, thereby cause the joint embrittlement; Protect when bad, stress cracking and cold crack can occur; If the butt joint end face is stained by moisture, grease etc., just gas hole defect can occur.
2, the welding procedure difficult point of pure titanium foil.(1) easy deformation.When the very thin thickness of titanium plate, heat to the influence of material just clearly, therefore, after expanding with heat and contract with cold, the distortion of titanium plate is clearly.The weld seam situation was inconsistent before and after this just caused, for welding has increased difficulty.(2) burn easily.In welding process, if there is the heat radiation condition of poor part, occur just have the phenomenon of burning in this position, have a strong impact on the quality of weld seam.(3) butt joint assembling difficulty.For the titanium foil of 0.05mm, if strict butt joint assembling except the assembly precision to fixture system has very high requirement, but also needs artificial careful adjustment.(4) material composition of pure titanium foil has determined that it is a kind of material of softness, and the poor operability of flexible material, its operation comprises blanking, assembles, compresses and fixes etc., poor operability just because of these processes, therefore the precision to them has proposed quite high requirement, otherwise can cause artificial weld defect.
For the welding of pure titanium or titanium alloy material, existing investigative technique concentrates on the problem that adopts laser weld to solve its welding performance difference mostly, also has part to adopt electron beam welding, TIG weldering and plasma arc welding (PAW) welding.But electron beam welding titanium sheet metal cost is too high, and the protection effect of laser beam and TIG welding titanium sheet metal is relatively poor.
Through the literature search of prior art is found, " rare metal wall bulletin " 2008 the 27th phase the 3rd curly hair has been shown Zhang Xiaoming and has been translated selected passages one piece of article that is entitled as " solderability of pure titanium plate butt welding " from Japanese academic journal.Proposed the method with the industrially pure titanium (TP340C, 2 kinds of JISH4600) of plasma arc welding (PAW) throat thickness 0.6mm in the literary composition, weld seam and rolling direction are at right angles carried out butt welding.By result for retrieval as can be known, thickness connects in the micro-plasma arc welding of 0.6mm and following pure titanium sheet metal and yet there are no report.
Summary of the invention
The object of the invention is to fill up the blank of present micro-plasma arc welding in pure titanium foil (the ultra-thin pure titanium plate of thickness below 0.1mm) welding, has proposed the method with micro-plasma arc welding welding 0.05mm pure titanium foil.Technical scheme of the present invention is as follows:

(2) remove pure titanium foil and treat toe greasy dirt on every side;
(3) pure titanium foil to be welded is assemblied on the anchor clamps of fixture system, and the toe to be welded of two pure titanium foils need cost the distance of 0.1～0.2mm, guarantee that weld seam is on the groove of anchor clamps backing plate;
(4) welding gun of micro-plasma welding equipment is adjusted to position directly over the weld seam starting point;
When (5) welding, directly over weld seam, move forward, weld along weld seam by the driven by motor welding gun on the fixture system.Wherein, the technological parameter that micro-plasma arc welding connects is as follows: speed of welding is 15.8mm/s～19.4mm/s; torch height is 2.3mm～2.8mm; dutycycle is 40%～60%; the gas flow of ions amount is 0.36L/min～0.44L/min, and the protection throughput is 2.3L/min～2.9L/min, and the pulse current frequency scope is 50～1500HZ; the scope of pulse background current is 0.5～0.8A, and the scope of pulse peak current is 0.8～1.1A.When selecting the collocation of peak value and base value, guarantee that its average current size is 0.8A.
Above micro-plasma arc welding technology does not need to add in weld seam and fills metal.
The present invention has realized the micro-beam plasma arc butt welding of the pure titanium foil of 0.05mm, solve pure titanium foil welding distortion and burn problem, save the cost of the welding of pure titanium foil, help industry and promote.Filled up the blank of micro-plasma arc welding at the pure titanium foil welding field.
