Abstract
The utility model provides a thermocouple for pipe braze welding. A welding end of the thermocouple is wrapped by a nickel-chromium piece which is rectangular and has the length of 5mm and a width of 2 mm. The thermocouple for pipe braze welding can reach technological requirements of pipe welding, and can accurately measure the temperature of a welded pipe.
Description
Technical field
The utility model relates to a kind of thermopair for the conduit soldering, is used for the welding temperature of measuring guide.
Background technology
Conduit soldering thermopair is that the thermopair that diameter is very thin pierces in the heat-resisting porcelain tube of insulation, utilizes argon arc welding to be welded on the titanium alloy of different size and the edge of stainless steel port.Its technological requirement be pad apart from port less than 3mm, welding is wanted firmly and the port of conduit can not be burnt till breach, this is just so that increased difficulty to the welding of conduit, especially internal diameter is φ 3, φ 4 and the thin stainless-steel tube of wall.
Summary of the invention
The purpose of this utility model provides a kind of thermopair for the conduit soldering, can reach the technological requirement of conduit welding, and temperature that can Measurement accuracy welding conduit.
The technical solution of the utility model: be used for the thermopair of conduit soldering, be surrounded by the nickel chromium triangle sheet at the welding end of thermopair.
Described nickel chromium triangle sheet is rectangle, and long is 5mm, and wide is 2mm.
The beneficial effects of the utility model: adopt the long 5mm that is; wide for the nickel chromium triangle sheet of 2mm is wrapped in the welding end of thermopair, its effect one is the contact area that increases thermopair and conduit, makes temperature survey accurately and reliably; the 2nd, the protection thermocouple wire is in order to avoid burn when welding.
Description of drawings
Fig. 1 is the structural representation of thermopair.
Fig. 2 is the structural representation of nickel chromium triangle sheet.
Fig. 3 is the welding synoptic diagram of thermopair and nickel chromium triangle sheet.
Fig. 4 is the sectional view of conduit soldering thermopair.
Embodiment
As shown in Figure 1 to Figure 3, be used for the thermopair of conduit soldering, be surrounded by nickel chromium triangle sheet 2 at the welding end of thermopair 1.
Described nickel chromium triangle sheet 2 is rectangle, and long is 5mm, and wide is 2mm.
As shown in Figure 4, the welding process of conduit soldering thermopair and conduit 3:
1) cleaning, the polishing work before the welding: because argon arc welding, the cleanliness of conduit 3 pads are required stricter, need to polish for more than times until till meeting the requirements with fine sandpaper, otherwise do not weld.
2) making of nickel chromium triangle sheet: make long for 5mm, wide be the nickel chromium triangle sheet 2 of 2mm, it is wrapped in the welding end of thermopair 1.
3) control of welding current: originally because the electric current grasp is inaccurate, so that most of not prison welding is solid, and comes off and to use from conduit 3 in the use procedure of thermopair; Through the test of many times analysis, welding current is too small, and thermopair is not melted in conduit 3, after electric current is tuned up, easily conduit 3 is burnt till breach again; Repeatedly draw with specimen test finally by crossing, Current Control is when 1.5-2.0A, and conduit 3 not only firmly but also had not been burnt in welding.
4) control of weld interval: welding current determines that also be the key of welding quality weld interval after determining, weld interval, weak point can cause in the not welding, long can melting away thermocouple wire of time; Draw by repetition test, the Best Times of welding is 2 seconds, and this moment is best in quality.
5) control of soldering angle: determined welding current, weld interval, it is also very crucial to grasp soldering angle, after the welding gun starting the arc, electric arc is shifted to solder joint, when being 30 ° with conduit 3 tube walls welding quality is guaranteed.
Claims (2)
1. be used for the thermopair of conduit soldering, it is characterized in that: the welding end at thermopair (1) is surrounded by nickel chromium triangle sheet (2).
2. the thermopair for the conduit soldering as claimed in claim 1 is characterized in that: described nickel chromium triangle sheet (2) is rectangle, longly is 5mm, and wide is 2mm.
