Abstract
The invention relates to an electrode solving a spot welding non-core problem; the electrode comprises an upper electrode and a lower electrode, wherein the upper electrode head is a round plane, and the lower electrode head is a square plane; the upper and lower electrode heads both employ special outer contour plane design, and the special outer contour planar contact-making surfaces can change a spot welding current field, so the welding core can shift to a large piece end; in addition, the heat energy transfer is related to a contact area between the electrode and the contact parts, thus reducing first part a-end heat radiation, increasing second part b-end heat radiation, and solving the core shifting problem.
Description
Technical field
The present invention relates to a kind of electrode, a kind of electrode and method of work thereof being suitable to solve spot welding coreless.
Background technology
Available engine part (densification device steel bushing assembly), is the outer shroud of densification device, and material is 1Cr18Ni9Ti, two kind of first part a and the second part b resistance spot welding weld and combine (such as Fig. 1 and Fig. 2).Owing to two kinds of External Shapes exist significant difference, part b small-sized (such as Fig. 3), cause being difficult to form welding core.
Second part b need to be welded to the first part a medial wall by resistance spot welding; first part a is hollow cylinder; second part b is rectangular block shape body; owing to the size length × width × height of the second part b is 4.25mm × 2.5mm × 1.25mm; length and width is small-sized; and electrode pressure commonly reaches 0.15MPa during spot welding; electric current reaches thousand of A; and existing electrode head is typically hemisphere face shape; due to size difference, heat skew, easily conquassation or coreless when causing the second part b spot welding; if do not taked special measure, it is impossible to realize effectively welding.
Summary of the invention
The technical problem to be solved is to provide and a kind of be capable of two kinds of profiles and there is effectively the welding of part of significant difference, be suitable to solve electrode and the method for work thereof of spot welding coreless.
For solving above-mentioned technical problem, the invention provides a kind of electrode being suitable to solve spot welding coreless, comprising: upper electrode and bottom electrode, upper electrode tip portion is circular flat, and the head of bottom electrode is square planar。
For ensureing radiating effect and current field, the size of upper electrode should be tried one's best greatly, and it is dimensioned to cover the second part b, needs to put into soldering part a, and circle is prone to processing, therefore upper electrode is designed as circular flat；Bottom electrode is the least, and to reduce the heat radiation of the first part a, but its size can not be less than the second part b, otherwise during spot welding, the lateral surface of the first part a extrudes dell owing to supporting electrode surface little Yi, it is ensured that not spare part outside measurement requirement, thus bottom electrode is designed as square planar.
Concrete, a diameter of 6mm of the circular flat in described upper electrode tip portion, the size length of the square planar of described bottom electrode head × a width of 5mm × 3mm, circular flat is suitable to cover all the second part b, increasing heat radiation during the second part b spot welding, square planar is suitable to use at the lateral surface of the first part a.
During use, upper and lower electrode head is connected with the second part b, the first part a respectively, by the first part a and the second part b is contacted, and logical big electric current, between the first part a and the second part b exothermic melting because there being resistance, thus weld together and to obtain final weldment.
The technique effect of the present invention: the upper and lower electrode head of the electrode of the present invention all uses special outline planar design, the contact surface plane by special outline changes spot welding current field, nugget is made to offset to big part end, simultaneously, because heat transmission is relevant with the contact area of part with electrode, it is thus able to reduce by the first part a end heat radiation, increases the second part b end heat radiation, the problem solving core skew.
