Background technology
In the industries such as petrochemical industry, chemical fertilizer and Coal Chemical Industry, the crucial medium that corrosivity is strong, operating temperature is highAll adopt titanium pipe to carry, the welding quality in titanium pipe construction process moves to close to the production safety of device and weighsWant. But due to the very particularity of welding performance of titanium pipe material, when welding region metal temperature exceedes 250 DEG C notMust with N2、O2、H2Contact, namely must not be exposed in air, otherwise the mechanical performance of weld seam and corrosion resistantErosion hydraulic performance decline, can not meet instructions for use. Titanium pipe is in the time of welding, and spray at argon arc welding electrode holder in the molten bath of weldingIn the argon shield going out, but just welding weld seam out is not protected, and weld seam temperature at this moment exceedes250 DEG C, therefore this part weld seam needs argon shield and cools to below 250 DEG C.
Summary of the invention
The purpose of this utility model is for the problem existing in background technology, and a set of titanium pipe welding grade argon is providedGas cooling protection cover, prevents that titanium pipe weld seam in welding process is contaminated, guarantees that every quality of weld seam refers toMark.
The technical scheme that the utility model adopts is:
A kind of titanium pipe welding grade argon gas cooling protection cover, it comprises protective cover, siphunculus, steel wire, argon arc weldingElectrode holder folder, described protective cover is hollow and bottom is bottomless, and steel wire is packed in protective cover inside; Protective cover topPortion's center drilling, siphunculus be connected to protective cover top center tapping and backward bending be parallel to protective cover topPortion; Argon arc welding electrode holder folder is welded on the antetheca outside of protective cover, and is positioned on the axis at siphunculus pipe shaft place;Described argon arc welding electrode holder folder is for fixing argon arc welding electrode holder, and described siphunculus connects argon gas by rubber tube. Due toProtective cover is after argon arc welding electrode holder, and welding high temperature weld seam is out below protective cover, and argon gas is by protectionSteel wire in cover evenly blows on high temperature weld seam, plays protection and the cooling effect of butt welded seam.
Preferably, described argon arc welding electrode holder folder is welded on the antetheca outside of protective cover.
Preferably, the antetheca of protective cover is shorter than sidewall and the rear wall of protective cover.
Preferably, steel wire is 100 object stainless steel steel wires.
Preferably, the material of described protective cover, siphunculus, argon arc welding electrode holder folder is red copper.
In more excellent embodiment, described siphunculus diameter is 8mm.
In more excellent embodiment, described siphunculus diameter is 8mm, and siphunculus exceeds protective cover top 30mm, siphunculusBending is parallel to protective cover top and stretches out protective cover 15mm backward; The long 65mm of described protective cover, wide48mm, high 33mm, the red copper thickness of protective cover is 3mm; Described argon arc welding electrode holder folder diameter 33mm, height25mm, exceeds protective cover top 15mm, and the red copper thickness of argon arc welding electrode holder folder is 3mm.
Beneficial effect: titanium pipe welding grade argon gas cooling protection cover of the present utility model, can effectively prevent the weldering of titanium pipeSew the pollution of the gas such as nitrogen, oxygen, guarantee the welding quality of titanium pipe.
