Background technology
Known, when arc welding is in magnetic field environment, such as the electrolytic aluminium workshop, all kinds of conductive units in the workshop (trough rim bus, negative electrode, anode balance bus) distributing position difference, position and strong and weak different space dc electromagnetic fields in the workshop, have been produced, trouble has been brought to the arc welding maintenance work in the workshop in these magnetic fields, if surrounding magnetic field is very strong, makes some positions almost can not weld; Even can weld, because of unsettled magnetic field makes electric arc violent splashing takes place also, produce the arc blow phenomenon, also can cause appearance of weld bad simultaneously, cause welding quality to descend.
In order to solve an above-mentioned difficult problem, in the long-term production practice, people have summed up some eliminatings and have weakened method and the approach of magnetic field to the welding quality influence, as a minute magnetic method, non-arc-welding method and technique processing method that some are special.But these methods are used inconvenience, and limitation is very big, and welding quality is difficult to guarantee.
Summary of the invention
The utility model influences problems such as welding quality in order to solve existing arc-welding apparatus in that generation arc blow phenomenon under the magnetic environment is arranged, and a kind of diamagnetic interference arc welder is provided.
The utility model is to adopt following technical scheme to realize: a kind of diamagnetic interference arc welder, comprise arc welding gun and nozzle thereof, be provided with on the nozzle can shielding space magnetic field laterally, the magnetic head of longitudinal component, magnetic head is connected with excitation power supply.Adopt structural design of the present utility model, connect excitation power supply, the work magnetic field that magnetic head produced is shrouded around welding arc, and the longitudinal component in this magnetic field (magnetic-field component parallel with arc axis) is stronger, can reduce the relative size of space magnetic field cross stream component; Cross stream component (magnetic-field component vertical with arc axis) is in order to reduce or to offset the cross stream component in welding arc regional space magnetic field.Like this, work magnetic field can shielding space magnetic field cross stream component to the effect of electric arc, avoid the generation of arc blow, welding process is carried out smoothly, guarantee welding quality.
Described magnetic head is made of annular core and magnetizing coil, and magnetizing coil is connected with excitation power supply, and excitation power supply is used to produce stable, the reliable dc magnetizing electric current of continuous output, supplies with solenoid; Fix for the ease of magnetic head and nozzle, easy to process, border, nozzle below is provided with round platform, and annular core is socketed in outside the nozzle and the lower end is welded on the round platform.Also nozzle and annular core directly can be processed into one, described nozzle can be the existing commercially available different shape and the nozzle of size.
Because welding gun in use can produce very high temperature, adding upper magnetic head itself also can generate heat, so in order to prolong the service life of this device, uninterrupted in welding process, the long-time use, guarantee to weld and carry out smoothly, leave the annular gap as the water cooling chuck between described annular core and the nozzle, coolant outlet and cooling water inlet all are arranged on the nozzle top.
Three water-stop sheets are set in the described annular gap at least, make that the cooling-water flow passage is circuitous shape in the annular gap, increase the contact area of cooling water and nozzle and iron core, the assurance current are even.
Compared with prior art, the utility model can be in transverse field strength less than 5 * 10
-3Reliably use in the magnetic field of T, be applicable to the welding on electrical body not; Its use can be avoided electrolytic cell when maintenance unnecessary dismantlement work and the loss that brings of power failure, has considerable economic, and can be widely used in the welding process that external magnetic field disturbs; And volume is little, in light weight, can be loaded on the welding gun head and realize manual or welding automatically, can effectively overcome and reduce weld defect, improves weldquality.
