Abstract
The invention relates to a welding method, in particular to an electrical contact welding method. The invention aims at solving the problems of easy occurrence of brazing seam pores, poor pore filling, difficult exhaustion of gas and low brazed rate generated when resistance brazing is used for welding. The method comprises the following steps of: horizontally stacking two work pieces to be welded, naming the upper work piece to be welded as a contact point, naming the lower work piece to be welded as a contact bridge, and arranging brazing filler metal between the contact bridge and the contact point; connecting both ends of the contact bridge with a welding machine, powering on the welding machine, heating the brazing filler metal by using resistance heat produced by the contact bridge to melt and spread the brazing filler metal; then, vibrating the contact point or the contact bridge, and naturally moisturizing and spreading the brazing filler metal to form a responding layer after vibration stops; and finally, powering off the welding machine. The electrical contact welding method is used for welding an electrical contact.
Description
Technical field
The present invention relates to a kind of welding method, belong to welding technology field.
Background technology
The welding major part of electrician's contact is the welding of copper, silver and alloy thereof, and resistivity is very low, and thermal conductivity is very high, adopts electric resistance welding to weld very difficulty; Adopt then very low of efficient of common soldering.The combination of adopting preceding two kinds of welding methods is resistance brazing when welding, and not only quality is relatively stable, and efficient is also than higher.But; when solder was settled not at that time; bubbing or solder are overheated in the brazing process defectives such as some brazed seam pores, calking are bad occur through regular meeting; especially for the bigger workpiece of junction area; the more difficult discharge of gas; defective is more, and ratio of brazing area is also lower, and the mechanical property and the electric property of contact caused very big influence.
Summary of the invention
The purpose of this invention is to provide a kind of electrician's contact welding method, solve to adopt resistance brazing to weld to be prone to defectives such as brazed seam pore, calking be bad, especially for the bigger workpiece of junction area, the more difficult discharge of gas, ratio of brazing area is low, the problem that the mechanical property and the electric property of contact caused very big influence.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the method for the invention is realized by following steps: step 1: two workpiece to be welded are horizontally disposed with and are stacked together, the workpiece to be welded that is positioned at the top in two workpiece to be welded is called the contact, the workpiece to be welded that is positioned at the below in two workpiece to be welded is called and touches bridge, solder is placed touch between bridge and the contact; Step 2: will touch the bridge two ends and be connected with welding machine, and connect welding machine electric power, electric current only flows through and touches bridge, the resistance heat that the bridge generation is touched in utilization heats solder, make its fusing, sprawl, be 3s～40s the heat time heating time of touching bridge, and flowing through the electric current that touches bridge is 1000A～30000A; To the contact or touch bridge and vibrate, time of vibration is 2s～3s then; Stop vibration afterwards, make the solder nature wetting, sprawl, form conversion zone, be 5s～60s weld interval, the final cutting welding machine electric power.
The invention effect:
1, production efficiency is improved.Adopt vacuum brazing in the ordinary stove, need the time to be approximately 1h～8h; And adopt welding method of the present invention, at concrete workpiece to be welded, can be controlled between 5s～60s weld interval.
2, defectives such as brazed seam pore, calking be bad have been reduced effectively.Adopt ordinary soldering or resistance brazing, because the area of contact welding is bigger, the gas of settling reasons such as bubbing in improper, the brazing process or solder be overheated to produce because of solder is difficult to get rid of, and defective is many; And adopt welding method of the present invention, and by the vibration of ceramic rod or the vibration of backing plate, discharge that can effectively promotion bubble, brazed seam pore, calking are bad etc., and defective has obtained good restraining.
3, the welding ratio of brazing area is greatly improved.Ratio of brazing area is the effective standard whether the check contact burn-ons, and adopts the ratio of brazing area of ordinary resistance brazing very low, and few has only 50%; And adopt welding method of the present invention, nearly ratio of brazing area can be brought up to 90%, and working stability, improved the mechanical property and the electric property of contact, and can well be applied in the on-the-spot industrial production.
Description of drawings
Fig. 1 be the schematic diagram of realizing a kind of electrician's contact welding method of the present invention (adopt ceramic rod 4, and among the figure → be to right, ← be direction left), Fig. 2 is the schematic diagram (employing backing plate 6) of realization a kind of electrician's contact welding method of the present invention.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1 and 2 explanation, the described method of present embodiment is realized by following steps: step 1: two workpiece to be welded are horizontally disposed with and are stacked together, the workpiece to be welded that is positioned at the top in two workpiece to be welded is called contact 1, the workpiece to be welded that is positioned at the below in two workpiece to be welded is called and touches bridge 3 (convenient like this vibration, when if the resistance that touches bridge 3 is also big, heat production also can be more, help the fusing of solder 2 more and sprawl, enhance productivity), solder 2 placed touch between bridge 3 and the contact 1; Step 2: will touch bridge 3 two ends and be connected with welding machine 5, and connect welding machine electric power, electric current only flows through and touches bridge 3, the resistance heat that bridge 3 generations are touched in utilization heats solder 2, make its fusing, sprawl, be 3s～40s the heat time heating time of touching bridge 3, and flowing through the electric current that touches bridge 3 is 1000A～30000A; To contact 1 or touch bridge 3 and vibrate, time of vibration is 2s～3s then; Stop vibration afterwards, make solder 2 natures wetting, sprawl, form conversion zone, be 5s～60s weld interval, the final cutting welding machine electric power.
