Detailed description of the invention:
Below in conjunction with accompanying drawing, 1,2,3 couples of the present invention are described in further detail:
A welding procedure for fuse element, comprises the following steps:
(1) select a mash welder, melt to be welded and conductive plate are placed between mash welder top electrode, bottom electrode;
(2) regulate soldering tip position, make bottom electrode contact with weldment and apply pressure;
(3) by loop energising, melt and conductive plate two absorption surface surface are heated, local melting is formed and melts core, needs to move continuously, at the uniform velocity during spot welding;
(4) keep pressure after power-off, make to melt core and cool under stress, solidify formation solder joint, remove pressure, take out workpiece, complete a welding process;

In described soldering, spot welding position is inside conductive plate.
Shown in Fig. 1 composition graphs 2,3, melt 1 and conduction touch panel 3 are between top electrode 5, bottom electrode 4, during welding, top electrode 5 and bottom electrode 4 should keep parallel to each other, first regulate the position of soldering tip 2, top electrode 4 is made to contact with weldment and apply pressure, by loop 6 energising, melt 1 and conductive plate 3 liang of absorption surface surfaces are heated again, local melting, form nugget; Keep pressure after power-off, make nugget cooled and solidified formation solder joint under stress, remove pressure, take out workpiece, complete a welding process.
Circulation spot welding was made up of four root phases:
(1) pre-pressing stage: electrode drops to the current turns ON stage, guarantees electrode workpiece pressing, makes there is suitable pressure between workpiece;
(2) weld interval: welding current is by workpiece, and heat production forms nugget;
(3) hold time---cut off welding current, electrode pressure continues to be maintained until nugget and is solidified to sufficient intensity;
(4) stop time---electrode starts to be lifted to electrode and again starts to decline, and starts next weld cycle.
Before welding, electrode decline is treated weldment and is produced precompression, make it to fit tightly, welding current is by producing resistance heat during weldment, under soldering tip, between two weldments, contact point is in molten condition instantaneously, the solder joint formed after cooling is more firm, as condenser type reserve energy spot welding machine, utilize industrial-frequency alternating current to charge to capacitor after rectifier rectification, the electric energy be stored again through welding transformer electric discharge convert to low-voltage, energy comparison concentrates stable pulse current, produces resistance heat by metal welding by the contact point of welded piece.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when the technique and technology contents that can utilize above-mentioned announcement are made a little change or is modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
