Description
Technical field
The utility model relates to a kind of welding auxiliary equipment, particularly relates to a kind of titanium alloy pipeline welding argon filling and protects holder cover outward.
Background technology
Titanium at high temperature has great affinity to gases such as oxygen, hydrogen and nitrogen, and particularly in titanium welding process, this ability is more strong along with the rising of welding temperature.Facts have proved, if do not controlled the absorption of the gases such as titanium alloy and oxygen, hydrogen and nitrogen and dissolving during welding, bring great difficulty can to undoubtedly the welding process of titanium alloy welding joint.
In conventional soldering techniques; the welding process of titanium pipe needs to use the protection of argon filling outside holder cover; and common holder cover adopts oval or cylindrical holder cover; argon gas flow velocity is wherein too fast; thus affecting molten bath shaping, butt welded seam protected effect is undesirable, affects welding quality; cause solder yield low, thus cause construction production efficiency low.
Utility model content
For prior art above shortcomings; the purpose of this utility model is how to solve existing outer protection holder and covers in use that argon gas flow velocity is too fast; affect the problem of welding quality; a kind of titanium alloy pipeline welding argon filling is provided to protect holder cover outward; the flow velocity of argon gas can be reduced; guarantee weld seam not by air impact, improve weld is accepted rate, ensure that the efficiency that construction is produced.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is such: holder cover protected outward by a kind of titanium alloy pipeline welding argon filling, comprise cover body and tunger tube, described cover body is that the open box body structure in downside is closed in upside, it is characterized in that: the downside of described cover body two lateral walls is curved, make to be close to titanium alloy tube pipeline outer wall on the downside of cover body, the downside of another sidewall of this cover body or two side is provided with several breach;
In cover body, level is provided with a copper mesh, and described copper mesh is positioned at the top of cover body; One end of described tunger tube is stretched in cover body from the sidewall of cover body, and extends to the opposite side of cover body, and one end that this tunger tube stretches into cover body is closed; The part of horizontal that described tunger tube stretches in cover body is arranged, and on the upside of cover body and between copper mesh, the upside stretching into the part in cover body at tunger tube offers some ventholes along its length.
Further, the surrounding of described copper mesh and the sidewall weld of cover body are fixed together, and its specification is at least 100 orders.
Further, described cover body is made up of copper coin or titanium alloy, and its thickness is 0.8-1mm.
Compared with prior art, the utility model tool has the following advantages: structure is simple, easy to use; When carrying out construction protection with it, argon gas leads in distributing pipe by inlet tube, through top ejection, is uniformly distributed and cushions; Meanwhile, because the direction of venthole is towards the side deviating from copper mesh, when air-flow through cover body upper side reflection after again through copper mesh, obtain and be again uniformly distributed and cushion, the clothes made of brocade reduces air velocity, makes air-flow more stably protect weld seam, thus obtains good protected effect; Guarantee weld seam not by air impact, improve weld is accepted rate, ensure that the efficiency that construction is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.

In figure: 1-cover body, 2-tunger tube, 3-copper mesh, 4-venthole, 5-breach.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1, Fig. 2, holder cover protected outward by a kind of titanium alloy pipeline welding argon filling, comprises cover body 1 and tunger tube 2, described cover body 1 is for closing the open box body structure in downside in upside, in manufacturing process, described cover body 1 is made up of copper coin or titanium alloy, and its thickness is 0.8-1mm; In welding process, thermal diffusivity is better, and stability is better, longer service life.The downside of described cover body 1 two lateral walls is curved, makes to be close to titanium alloy tube pipeline outer wall on the downside of cover body 1; The downside of this another sidewall of cover body 1 or two side is provided with at least one breach 5, makes argon gas flow, thus enable argon gas blow welding gun tungsten electrode in welding process.
In cover body 1, level is provided with a copper mesh 3, and described copper mesh 3 is positioned at the top of cover body 1; The surrounding of described copper mesh 3 and the sidewall weld of cover body 1 are fixed together, and its specification is at least 100 orders; Thus ensure that argon gas can be uniformly distributed further, the flowing velocity of the low argon gas of a step-down of going forward side by side.
One end of described tunger tube 2 is stretched in cover body 1 from the sidewall of cover body 1, and extends to the opposite side of cover body 1, and one end that this tunger tube 2 stretches into cover body 1 is closed; The part of horizontal that described tunger tube 2 stretches in cover body 1 is arranged, and on the upside of cover body 1 and between copper mesh 3, the upside stretching into the part in cover body 1 at tunger tube 2 offers some ventholes 4 along its length.
When carrying out construction protection with this outer protection holder cover, argon gas leads in distributing pipe by inlet tube, through top ejection, is uniformly distributed and cushions; Simultaneously, because the direction of venthole 4 is towards the side deviating from copper mesh 3, when air-flow through cover body 1 upper side reflection after again through copper mesh 3 time, obtain and be again uniformly distributed and cushion, the clothes made of brocade reduces air velocity, make air-flow more stably protect weld seam, thus obtain good protected effect; Guarantee weld seam not by air impact, improve weld is accepted rate, ensure that the efficiency that construction is produced.
In welding process, live welding gun rifle head (tungsten electrode and porcelain mouth 1/3rd) with this outer protection holder cover cap, stretch in cover body 1 by the breach 5 of welding gun rifle head part from cover body 1, facilitate welder to observe molten bath; Adopt small area analysis during welding, and want little swing or do not swing when welding wire adds molten bath filling weld seam, thus ensure that the argon gas in welding gun and the argon gas in protective cover form convection current, guarantee the shaping of weld seam, avoid causing the defects such as pore; Outer protection holder cover operator will with welder's close fit, make outer protection hold in the palm cover and then welding gun slowly movement, thus ensure that cover available protecting molten bath is held in the palm in outer protection.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
