Description
Technical field
The present invention relates to the preceding process of surface treatment of titanium or titanium alloy welding, especially the surface cleaning technology before the titanium or titanium alloy welding belongs to welding technology field.
Background technology
Titanium alloy has the specific tenacity height, good solidity to corrosion, density is little and series of advantages such as toughness and weldability preferably, in aerospace, petrochemical complex, shipbuilding, automobile, the application that departments such as medicine all succeed.Welding is the main mode of connection of titanium or titanium alloy spare, because the metal titanium activity is strong, long-term exposure is under conditions of air, the surface very easily forms the oxide film of one deck densification, make the titanium or titanium alloy surface passivation, and in mechanical processing process residual greasy dirt attached to the surface, thereby cause easily generating in the welding process welding flaw of pore, had a strong impact on the welding quality of titanium or titanium alloy structural part, thus the service requirements that does not reach product.Therefore before welding, to carry out clean to the surface of titanium or titanium alloy structural part usually.
Pickling and alkali washing process are adopted in surface treatment before traditional titanium or titanium alloy welding.The conventional used acid solution of acid washing method is by industrial hydrofluoric acid HF, and industrial nitric acid HNO3 and water H2O are 1 by volume: the ratio of 4-8: 5-10 is formulated, and the used solution composition of alkali cleaning is by NaOH 40g/L, and NaCO3 20g/L is formulated.Owing to use pernicious harmful toxic matters such as a large amount of strong acid, highly basic in traditional pickling and the alkali washing process, environment is caused great pollution, and, seriously restricted titanium or titanium alloy precision component Development of Welding Technology the effect that prevents to weld gas hole defect and not obvious.
Summary of the invention
The objective of the invention is to problem at the process of surface treatment existence before at present traditional titanium or titanium alloy welding, provide a kind of welding of titanium or titanium alloy efficiently preceding process of surface treatment, both reduced environmental pollution, improve cleaning performance again, prevent to generate in the welding process pore, improve the welding quality of titanium or titanium alloy structural part.
Realize that technical scheme of the present invention is as follows:
A kind of titanium or titanium alloy welding surface pretreatment process that prevents pore is characterized in that, comprises the steps:
(1) with Sodium dodecylbenzene sulfonate 1-2g, anhydrous sodium sulphate 0.5-1g, Triton X-100 0.01-2g, anhydrous sodium bicarbonate 0.05-0.8g, pure water or distilled water 10L mix according to the above ratio and stir, and are mixed with scavenging solution;
(2) titanium to be welded or titanium alloy weldment are put into described scavenging solution and soaked 5-10 minute, and with 120-400# liquid honing face of weld, bruting process is carried out in cleaning solution, metalluster occurs up to face of weld;
(3) titanium that above-mentioned process is polished or titanium alloy weldment are placed on and carry out ultrasonic cleaning, ultrasonic frequency 50-100HZ, scavenging period 5-10min in tap water or the distilled water;
(4) will put into drying baker oven dry, temperature 100-150 ℃, time 20-30min through the titanium or the titanium alloy weldment of ultrasonic cleaning;
(5) to titanium or the welding of titanium alloy weldment through above-mentioned cleaning and oven dry.
Titanium of the present invention or titanium alloy welding pretreatment technology, solved the technical barrier of the gas hole defect after titanium or titanium alloy weld, be applicable to as resistance spot welding, the seam weldering, the TIG weldering, Laser Welding, welding processs such as electron beam welding, technology is simple, compare with traditional pickling and alkali cleaning method, Sodium dodecylbenzene sulfonate of the present invention and Triton X-100 are the chemical ingredientss that the metal cleaner industry is known, Sodium dodecylbenzene sulfonate, be a kind of anion surfactant, have good perviousness and cleansing power with hydrophilic emulsifying property.Triton X-100 is the condenses of a kind of alkylphenol and oxyethane, belongs to nonionic surface active agent, have good emulsification, wetting, the performance that spreads, deoils, and anhydrous sodium sulphate and sodium bicarbonate is common industrial salt.Strong acid that traditional pickling cleaning use is a large amount of such as sulfuric acid, hydrofluoric acid, nitric acid, and a large amount of highly basic such as sodium hydroxide etc., serious environment pollution are used in alkali cleaning.Clean-out system pH value of the present invention is weakly alkaline, for the purpose that realizes to reach, composition through the prescription of experimental study repeatedly, environmentally safe, it is the industrial technology of the friendly type of ring mirror, and production efficiency has improved 1-2 doubly, and resulting weld strength reaches the weld seam requirement of QJ1666-95, has improved the overall quality of weld seam and welding assembly greatly.
