Description
Technical field
The utility model relates to metal working technical areas, and in particular, to spot welding is grounded Nut column.
Background technique
Arc discharge welding is that stud is packed into collet, after stud is contacted with plate, promotes spiral shell by the lifting device in welding gun
Column is generated secondary electric arc (maintaining burning arc), the main arc then to ignite between stud tip and workpiece using reduced-current,
Melt workpiece and stud, the time to be welded terminates, stud is moved at workpiece, makes its connection fusion；It cuts off the power, molten bath
Solidification, cooling, complete entire welding process.
Spot welding is that weldment is soldered on individual points of joint contact surface.Spot welding requires metal to have preferable modeling
Property.It is first that weldment removing surface is clean when welding, then the plate overlap joint welded is assembled, it is pressed between two column copper electrodes,
Applied force compresses.When passing through sufficiently large electric current, a large amount of resistance heat is generated in the contact position of plate, by center most thermal region
Metal is heated to high-ductility or molten state quickly, forms the liquid state molten pool of a lens shaped.Continue to keep pressure, disconnects electricity
Stream forms a solder joint after metal is cooling.
With new energy sources for automobile, lightweight, grounding nut column will be applied more widely as a kind of fastener.It is existing
Grounding nut column is using arcing welding structure corresponding to arcing Welding, since the welding parameter of arcing Welding and operation are not easy
Control is easy to cause weld stomata more and has burning phenomenon, so as to cause grounding nut column failure welding.Therefore it provides one
The grounding nut column that kind can be suitable for the more mature spot-welding technology of technique is this field technical problem urgently to be solved.
