1, the welding of titanium welded tube is a kind of continuous welding of not adding any metal material.Density is little, and the difficulty of welding is also just big.
2, titanium has very high heat-resisting quantity.Not only need high welding temperature, and welding equipment that need match and facility.
3, in the high-temperature soldering process, the metal very easily effect of oxygen down can produce oxidation and influence the quality of weld seam.Therefore, the welding process of important component (comprise and melt metallic crystal and cooling) must adopt protective gas strictly to protect, with the adverse effect of starvation butt welded seam.
Practice shows: titanium is different with the welding of stainless steel material, needs the protective gas protection of based on very high purity.At present, the titanium welded pipe product line in the use is though its welding process is all by protective gas protection, the welding manner that is mostly open type (seeing Fig. 1 for details) that adopts.Therefore, the problem that has the following aspects:
1, the protection of protective gas is difficult for tightly, and airborne oxygen infiltrates weld seam easily, causes weld seam at high temperature oxidation to take place and causes the decline of weldquality.
2, in a single day pad receives the influence that " beam wind " brushes, and " tongues of fire " that welding gun sprays are very easily blown partially, cause the decline of weldquality, even the phenomenon of weldering, rosin joint occurs leaking.
3, in order to guarantee carrying out smoothly and satisfying the weldquality requirement of welding process, the welding manner of open type needs the highly purified protective gas of labor.Therefore demanding developing the closed continuous welding device of novel titanium urgently, is the difficulty that runs into to solve present welding titanium.
Summary of the invention
The purpose of the utility model is to solve existing the problems referred to above of open type welding titanium in the prior art, and a kind of closed continuous welding device of titanium of novelty is provided.The utility model designs a kind of closed continuous welding device of titanium of novelty, comprises frame, elevating adjusting device, weld bond mould, welding gun, guiding mould, protective gas access tube, it is characterized in that: an airtight casing is arranged; Casing covers the frame top; The bottom surface of casing links to each other with the frame sealing, and adjusting device, weld bond mould, guiding mould all are positioned at casing, and welding gun is stretched in the casing by the opening on the casing; Front end at casing is provided with the pipe import; Be provided with tubing outlet in the rear end of casing, the protective gas access tube is positioned on the axis of pipe mouth of pipe, and the gas outlet of protective gas access tube is corresponding with the pad of welding gun.It is characterized in that: airtight casing has corrosion resistant plate to process, and on the casing above the pad, offers transparent visiting window, so that observe and adjust the position of pad.It is characterized in that: on tubing outlet frame, be embedded with rubber seal; It is characterized in that: the welding gun on the casing stretches into and is embedded with sealing rubber ring on the opening; Between driving shaft on the adjusting device and the through hole on the casing rubber ring is arranged, it is characterized in that: on the casing protective gas access tube arranged.The utility model has the advantages that the planarization of the stable and weld seam that has not only guaranteed welding arc, and fundamentally stopped the oxidative phenomena that high-temperature soldering is brought to face of weld, weldquality significantly improves.Simultaneously, airtight relatively casing makes the consumption of protective gas obtain obvious reduction.

The specific embodiment
The open type principle explanation of prior art by the band steel after product specification (diameter) the requirement cutting, twists into " pipe " of the straight shape slit of band through the continuous modification of former (before being arranged at this device) multi-pass.When the pipe slit passes through pad continuously; The high temperature " tongues of fire " that welding gun sprays just melts the metal of slit both sides apace; And in solidification process; " weld bond mould " by both sides clamps, and slit is eliminated (metal after the thawing merges rapidly when solidifying), thereby reaches the purpose of continuous welding.Melt and setting up period at metal, must adopt protective gas strictly to protect, in case metal produces quick oxidation and influences welding quality under high-temperature condition.Wherein: the protective gas of slit bottom (in the pipe) (" protective gas in the welding ") feeds the pad (see figure 1) by a small tubes, and the protective gas on slit top is then by spraying in " welding gun " circumferential weld.The continuous welding mode of open type that Here it is.
