Description
Technical field
The utility model belongs to argon arc welding technology field, in particular to a kind of tungsten argon arc welding protective hood.
Background technique
Due to titanium and its alloy poor thermal conductivity, heat dissipation is slow, and activity is strong, easily contacts with air and oxidation reaction occurs, welding
Oxidizing slag defect is formed in seam, therefore titanium welding needs special protective device；The welding of titanium exchanger tubes and tubesheets, due to
Welding position is special, and used argon arc welding drags that cover inert gas shielding range is small, flowing is fast, cannot protect to weld seam herein
Shield makes weld seam various defects occur, causes quality problems, causes weld seam pressure testing leak or reduces the weld seam service life, weld seam occurs
The failure rate of problem improves.
Summary of the invention

Across column setting is shunted, it is circumferentially uniformly provided with multiple ventholes around tungsten electrode on shunting column, is connected on shunting column tubaeform
Cover, tungsten electrode bottom are located within tubaeform cover, are connected between suction nozzle and tubaeform cover inside by venthole.
Preferably, silk screen group is fixed in tubaeform cover, the tungsten electrode passes through the setting of silk screen group from top to bottom.
Preferably, the tubaeform cover opening end face is the angled end-face being obliquely installed with tungsten electrode.
Preferably, tapped through hole is equipped at the top of welding gun short tube, pressure cap is threaded in tapped through hole.
Preferably, it shunts column outer wall and is equipped with external screw thread, the first internal screw thread is equipped in welding gun short tube inner wall, in tubaeform cover
Top, which is integrally formed, is equipped with connecting column, and the second internal screw thread, the shunting column upper half and the first internal screw thread are equipped in connecting column
It is threadedly coupled, shunts column lower half and be threadedly coupled with the second internal screw thread.
The phase by welding gun short tube, shunting column and tubaeform cover three is had the beneficial effect that possessed by the utility model
Mutual mating reaction makes the intracorporal argon gas of tubaeform cover more evenly, tungsten electrode and its weld seam under the adequately protecting of argon gas, avoid with
Oxygen contact in air, makes weld seam from oxidation, shaping surface is good, it is ensured that the quality of weld seam.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of tungsten argon arc welding protective hood, the welding gun short tube 5 including bottom opening, in 5 side of welding gun short tube
It is integrally formed the suction nozzle 9 being equipped with for being filled with inert gas on wall, tapped through hole, 6 spiral shell of pressure cap are equipped at the top of welding gun short tube 5
Line is connected in tapped through hole, and tungsten electrode 7 is coaxially fixed in pressure cap 6, is connected in welding gun short tube 5 and is shunted column 10, is being divided
Fluidization tower 10 is equipped with the tungsten electrode for fixing tungsten electrode 7 and presss from both sides 8, and the tungsten electrode 7 passes through from top to bottom shunts the setting of column 10, is shunting column
Multiple ventholes 4 circumferentially are uniformly provided with around tungsten electrode 7 on 10, are connected with tubaeform cover 2,7 bottom position of tungsten electrode on shunting column 10
Within tubaeform cover 2, it is connected between suction nozzle 9 and tubaeform 2 inside of cover by venthole 4.
Silk screen group 11 is fixed in tubaeform cover 2, the tungsten electrode 7 passes through 11 setting of silk screen group from top to bottom, thus
So that it is more uniform more to mitigate concentration into the argon gas in tubaeform cover 2, entire protection zone is increased.It is described tubaeform
2 opening end face of cover is the angled end-face 1 being obliquely installed with tungsten electrode 7, consequently facilitating the weld seam position from being convenient at angled end-face 1
It sets.
For the ease of welding gun short tube 5, shunt between column 10 and 2 three of tubaeform cover it is quick connect and detachable maintaining,
It is equipped with external screw thread shunting 10 outer wall of column, is equipped with the first internal screw thread in 5 inner wall of welding gun short tube, in tubaeform 2 top one of cover
Molding is equipped with connecting column 3, and the second internal screw thread, 10 upper half of shunting column and the first internal screw thread screw thread are equipped in connecting column 3
Connection shunts 10 lower half of column and is threadedly coupled with the second internal screw thread.
When the utility model is used, argon gas passes through suction nozzle when electrification 7 lower pointed end of tungsten electrode and the arc welding of workpiece weld bond
9 enter inside welding gun short tube 5, then enter in tubaeform cover 2 after being shunted by shunting column 10, pass through tubaeform cover 2
Internal silk screen rolls into a ball 11 further progresss buffering homogenization, makes argon gas in tubaeform cover 2 more evenly, tungsten electrode 7 and its weld seam
It under the adequately protecting of argon gas, avoids contacting with the oxygen in air, makes weld seam from oxidation, shaping surface is good, it is ensured that weldering
