Description
Art
The utility model belongs to machinery industry field of welding processing.
Background technology
Titanium is as a kind of active metal; be more than 300 DEG C in temperature and just inhale hydrogen in a large number, more than 400 DEG C oxygen uptakes, cause material property to decline; difficulty accordingly in welding increases, and this just requires to be protected the welding heat affected zone of temperature more than 300 DEG C and weld seam in welding process.Mostly adopt the argon arc welding under inert gas or vacuum condition at present, even if when welding meets technological parameter completely, titanium weld seam there will be golden yellow sometimes---the yellowish color of purple transition or even pore.Because the quality of gas shield effect; can be judged from the color of titanium face of weld; so the weld seam of this color illustrates that argon shield effect is bad; weld seam high-temperature oxydation; the hydraulic performance decline of weld seam; cause welding quality defective, affect the normal manufacturing schedule of enterprise, become the difficult problem that restriction titanium eguipment manufactures.Therefore, need a kind of new protective device, guarantee that argon gas is to the guard time of titanium weld seam and effect, fundamentally solves problems.
Summary of the invention
The problem that we will solve is: overcome titanium material and in argon arc welding process, cause weld seam to produce hydrogen embrittlement, pore and tungsten clip because gas shield is bad the weld defect and affect the problem of weldquality such as to mix.
The utility model provides a kind of titanium material welding argon protective device, and its structure comprises gas shield cover and lower gas shield groove two large divisions; Upper gas shield cover structure has: welding torch 1, larynx hoop 2, tail drag cover 3, breather pipe 4, porous plate 5; Argon-arc torch can clamp by larynx hoop 2, and tail drags cover 3 to be connected with larynx hoop 2, with some apertures bottom breather pipe 4, is positioned at above porous plate 5; Lower gas shield groove structure is: steel plate groove 6, porous plate 7, air inlet pipe 8; Wherein porous plate 7 is positioned at the middle part of steel plate groove 6, and air inlet pipe 8 enters steel plate groove 6 below porous plate 7.
Each parts of described titanium material welding argon protective device all connect with Type of Welding, and porous plate 5, porous plate 7 thickness are 6-10mm, and aperture is φ 4-6, and adjacent aperture centers distance is 8-12mm; Breather pipe 4 is the light-wall pipe of diameter phi 8-12, has 6-12 diameter phi 3-5 aperture to be uniformly distributed bottom it.Width and the thickness of steel plate groove 6 steel plate are not less than 100mm and 14mm respectively, and all the other described each parts materials are brass.
The operation sequence of titanium material welding argon protective device is as follows: weldment is placed on lower gas shield groove by A, air inlet pipe 8 is connected with argon gas; Upper gas shield cover is placed in above weldment by B, with larynx hoop, argon-arc welding gun is fixed on upper gas shield cover front end, and adjustment welding torch and workpiece distance, be connected breather pipe 4 with argon gas; C opens argon gas adjustment charge flow rate, by welding after air displacement a period of time in upper gas shield cover, lower gas shield groove.
The beneficial effects of the utility model are: this kind of novel titanium material welding argon protective device makes protection position argon gas stream steadily dynamic; stop the generation of the unfavorable factor such as suction hydrogen, oxygen uptake in weld seam molten bath in titanium material welding process completely, ensure that processing performance and the mechanical property of welding point.Its structure is simple, and cost is low, and Welded Joints surface protection excellent, has saved manufacturing cost greatly, improves production efficiency and quality.

Detailed description of the invention
With reference to accompanying drawing, the present invention is illustrated.
The utility model structure comprises gas shield cover and lower gas shield groove two large divisions; Upper gas shield cover structure has as shown in Figure 1: welding torch 1, larynx hoop 2, tail drag cover 3, breather pipe 4, porous plate 5; Argon-arc torch can clamp by larynx hoop 2, and tail drags cover 3 to be connected with larynx hoop 2, with some apertures bottom breather pipe 4, is positioned at above porous plate 5; Lower gas shield groove structure has as shown in Figure 2: steel plate groove 6, porous plate 7, air inlet pipe 8; Wherein porous plate 7 is positioned at the middle part of steel plate groove 6, and air inlet pipe 8 enters steel plate groove 6 below porous plate 7.All connect with Type of Welding with upper-part, porous plate 5, porous plate 7 material are brass, and thickness is 8mm, and aperture is φ 5, and adjacent aperture centers distance is 10mm.Breather pipe 4 is the thin-wall copper pipe of diameter phi 10, has 8 diameter phi 4 apertures to be uniformly distributed bottom it.
As shown in Figure 1, cover 3 top is dragged, through porous plate 5 through tail after upper gas shield cover argon gas enters breather pipe 4 from air admission hole.Porous plate mainly plays air sifter and distribution, makes gaseous state be laminar flow, and argon gas flowing is more steady.Described tail drags cover 3 material to be brass.
As shown in Figure 2, lower gas shield groove is the back-protective of welding bead.Consider welding deformation, we adopt the steel plate groove 6 with porous plate 7, and width and the thickness of steel plate are not less than 100mm and 14mm respectively.Porous plate 7 plays air sifter and distribution equally, and argon gas is flowed steadily.Before welding, groove first should replace a period of time with argon purge.
The operation sequence of titanium material welding argon protective device is as follows: weldment is placed on lower gas shield groove by A, air inlet pipe 8 is connected with argon gas; Upper gas shield cover is placed in above weldment by B, with larynx hoop, argon-arc welding gun is fixed on upper gas shield cover front end, and adjustment welding torch and workpiece distance, be connected breather pipe 4 with argon gas; C opens argon gas adjustment charge flow rate, by welding after air displacement a period of time in upper gas shield cover, lower gas shield groove.
