Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises arcing welding gun 9, welding machine main frame 15 and negative pole cable 14; Welding machine main frame 15 is connected with negative pole cable 14 by source of welding current negative pole interface 7, and welding machine main frame 15 is connected with arcing welding gun 9 with control relay connection jaws 5 with welding switch by source of welding current anode interface 6; Ceramic ring 10 and weldering nail 11 are connected on the rifle head of arcing welding gun 9 successively, together with the copper lug 12 of weldering nail 11 bottom and cable 13 are crimped onto by hydraulic tongs; During welding by negative pole cable 14 by magnet attraction on metal structures 16, then by the arcing welding gun 9 that is provided with ceramic ring 10 and weldering nail 11, the copper lug 12 of crimping cable 13 is pressed onto on metal structures 16, carries out welding operation.
Wherein, battery is provided with in welding machine main frame 15, can adopt lithium battery, shell is provided with indicating meter 1, source of welding current charging inlet 2, controls power source charges interface 3, welding machine electric power switch 4, and the both sides of indicating meter 1 are respectively equipped with source of welding current charging inlet 2 and control power source charges interface 3; The end of above-mentioned negative pole cable 14 is fixed with strong magnets.
In addition, control circuit is provided with in welding machine main frame 15, control circuit comprises delay control circuit c, main relay d, control relay e, source of welding current a is electrically connected to arcing welding gun 9 by main relay d, control power supply b and be connected to control relay e by delay control circuit c, control relay e is connected to the arcing coil of arcing welding gun 9 inside by welding switch 8.
Welding process of the present utility model is: on arcing welding gun 9, first install ceramic ring 10 and weldering nail 11, again the weldering nail 11 on arcing welding gun 9 is put into the hole of copper lug 12, apply to defeat to the copper lug 12 on metal structures 16 necessarily downwards by arcing welding gun 9, when pulling the welding switch 8 on arcing welding gun 9 after pressing, delay control circuit now in cathodic protection welding machine is switched on starts working, main relay is started immediately after delay control circuit is started working, now the normally opened contact of main relay is connected, the contact that welding current flows through main relay from the positive pole of the source of welding current flows to weldering nail 11 to arcing welding gun 9 again, due to weldering nail 11 and metal structures 16 close contact, electric current can arrive on metal structures 16 smoothly, because metal structures 16 are connected with negative pole cable 14, so electric current arrives the negative pole of the source of welding current through negative pole cable 14 by metal structures 16, material is thus formed a complete welding current loop, current value is close to 200A, after 1 second, delay control circuit connects control relay again, the magnetic force produced after arcing coil electricity makes the conductive shaft in brazing rifle upwards lift about 1mm, suddenly make weldering follow closely 11 to be separated a little gap with metal structures 16 will inevitably to produce strong electric arc welding between nail 11 and metal structures 16 when there being welding current to pass through, the central temperature section of this electric arc is up to more than 5000 DEG C, thus within the extremely short time, make weldering follow closely 11 top fusings, on metal structures 16, form a welding pool simultaneously.After 50 milliseconds, the delay control circuit of welding machine makes control circuit relay disconnect, the magnetic force of arcing coil disappears, continue as weldering nail 11 downwards in the effect of arcing welding gun inner spring screen resilience and provide certain pressure, after 200 milliseconds, delay control circuit makes main relay disconnect, force disconnect welding current loop, 2 seconds backward above vertically removes arcing welding gun, and destroys the afterbody of weldering nail 11 with hammer, and so far welding process is complete.
