Abstract
The utility model relates to a prestressed spot-welding electrode which is composed of two metals (1, 2). One end of each of the two metals (1, 2) is a tip part (3), wherein, an insulator (4) is firmly combined between the two metals (1, 2). The space between the tip parts (3) is provided with no insulator and is contacted with stress. The prestressed spot-welding electrode directly conducts spot weld to a metal wrapped with an insulator (such as insulating varnish), simplifies the welding process of spot weld, and enhances the quality of products. The prestressed spot-welding electrode is suitable to electronic industries and other fields, and is particularly suitable to the weld of microelectronic elements.
Description
The utility model relates to a kind of some welding electrode.
Point electric welding welding is to produce heat when electric current passes through to need weld metal (silk) and another metal, and it is welded together.The metal (silk) of welding is outer insulant (as being surrounded by insulated paint) if need, and electric current can not pass through, and welding also can't be carried out.Traditionally, must remove the insulant that needs weld metal (silk) outer, just can carry out an electric welding welding, removing insulated paint is two different operations with some electric welding welding, not only loaded down with trivial details, time-consuming, and product quality is difficult to ensure.
The purpose of this utility model is to provide a kind of need not remove the outer insulant (lacquer) of weld metal (silk), directly carry out the electrode that an electric welding is welded.
The utility model is achieved in that it is made of two metals, and an end of two metals becomes tip portion, between two metals insulant and strong bonded is arranged, but naked thing and contact with stress then between the tip portion.Two metals are refractory metal.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is a profile of the present utility model.
The utility model is by two metals (1,2) constitute, one end of two metals becomes tip portion (3), two metals (1,2) are molybdenum, long 32.5mm, diameter is half Cylinder of 3.25mm, insulant (4) and strong bonded are arranged, but naked thing and with stress contact then between the tip portion (3) therebetween, tip portion (3) end is long to be 0.45mm, highly to be 1.0mm for 0.5mm, bottom width.
During work, when the tip of prestressing force point welding electrode with the need weld metal (silk) that is surrounded by insulant (as insulated paint) touches and during turn-on current, eletrode tip produces electric arc, insulant (lacquer) thawing is pressed removed, exposing metal welds simultaneously.
The utility model can directly carry out an electric welding welding to the metal that is surrounded by insulant (as insulated paint), has simplified some electric welding welding procedure, has improved the quality of product, is applicable to electronics industry and other field, is particularly useful in the welding of microelectronic element.
Claims (2)
1, a kind of prestressing force point welding electrode is characterized in that it is made of two metals (1,2), one end of two metals (1,2) becomes tip portion (3), two metals (1, insulant (4) and strong bonded are arranged 2), but naked thing and contact with stress then between the tip portion (3).
2, prestressing force point welding electrode according to claim 1, two metals (1,2) are refractory metal.
