The specific embodiment
Embodiment.A kind of salt solution direct-current arc welder of thermocouple, as shown in Figure 1, it partly is made up of support, saline slot and control circuit, support comprises base 1, base 1 is provided with slide bar 2, is with slide block 3 on the slide bar 2, and slide block 3 is fixed on the slide bar 2 by screw 4, slide block 3 is provided with spring 5, spring 5 is provided with clip 6, and the below of clip 6 is provided with saline slot 7, and sodium chloride solution 8 is housed in the saline slot 7, be provided with battery lead plate 9 in the sodium chloride solution 8, battery lead plate 9 is electrically connected with control circuit.Control circuit is made up of rectifier bridge 10, current limliting potentiometer 11 and 12, the cathode output end of rectifier bridge 10 is connected with battery lead plate 9 through current limliting potentiometer 11, the cathode output end of rectifier bridge 10 be clipped in clip 6 on 13 be connected, the ac input end of rectifier bridge 10 is connected with the 220V AC power through switch 12.Clip 6 usefulness insulating materials are made.The ac input end of rectifier bridge 10 is parallel with power indicating circuit 14.
The welding process of thermocouple: the utility model is converted to direct current through control circuit with alternating current, galvanic positive pole is connected with battery lead plate 9 in the sodium chloride solution 8 through current limliting potentiometer 11, galvanic negative pole is connected with thermocouple 13 1 ends to be welded, connection can use the lymphogranuloma inguinale folder that thermocouple is clamped, for preventing that lymphogranuloma inguinale from crushing thermocouple wire, and guarantee that electric contact is good, available red copper foil encases the lymphogranuloma inguinale position, with thermocouple 13 1 ends hinge joint to be welded, be clipped on the clip 6, clip 6 should adopt insulating materials to make, to guarantee the safety of operation.At clip 6 is under the free state, and the gap between clip 6 and the slide block 3 is exactly the descending stroke of thermocouple.Adjust thermocouple 13 before the welding earlier and treat the spacing (about 2～3mm) of solder joint and sodium chloride solution 8 liquid levels, after adjusting, turn on the power switch, adjust current limliting potentiometer 11 and select welding current, welding current should be according to the diameter of thermocouple wire, and the decision of the material of thermocouple wire, and it is big that the bigger welding current of general thermocouple wire diameter also should be adjusted, the material melting point of thermocouple wire is high, and welding current also should be more greatly; For immobilization material, the noble-metal thermocouple of fixed diameter, the also available fixed resistance of this current limliting potentiometer replaces, after welding current is adjusted, press clip 6, what make thermocouple treats solder joint and sodium chloride solution 8 liquid level instantaneous short-circuits, treat to produce electric arc between solder joint and sodium chloride solution 8 liquid levels, because two hinged thermocouple wires melt rapidly, make thermocouple wire and sodium chloride solution 8 liquid levels produce a gap, but electric arc is set up, electric arc continues to keep between thermocouple wire and sodium chloride solution 8 liquid levels, and the high temperature of electric arc makes the rapid fusing in thermocouple termination and welds together, and forms smooth ball shape.The time was controlled at about 1 second after the starting the arc, and the time can determine by spot size as required, and the spot size that needs is big, keep the time of electric arc just long, the spot size that needs is little, keeps the time of electric arc just short, and the retention time of playing postwelding is directly proportional with spot size; Unclamp clip 6 after welding, clip 6 resets under the effect of spring 5, arc extinction, and welding is finished.
