Abstract
A positioned welding special electrode of a groove profile honeycomb structure resistor comprises a copper alloy upper electrode rod and a stainless steel electrode board. Copper alloy sheets are wrapped on the surface of the stainless steel copper electrode board, and the copper alloy upper electrode rod is fixed at one end of the stainless steel copper electrode board wrapped with the copper alloy sheets. According to the positioned welding special electrode of the groove profile honeycomb structure resistor, the thickness of the stainless steel copper electrode board is 4mm-6mm, and the width of the stainless steel copper electrode board is 20mm-25mm. The length of the stainless steel copper electrode board is matched with the depth of a groove arranged between an inner honeycomb core inside an element and an outer honeycomb core in the element.
Description
Technical field
The utility model belongs to the welding electrode field, particularly a kind ofly carries out resistance tack welding electrode before vacuum brazing for the grooved honeycomb seal structure.
Background technology
Honeycomb seal structure, its life-span is more than the twice of conventional seals, have that air-tightness is good, stability is high, high temperature resistant, wear-resistant and do not fall the multiple superior function such as piece, be widely used in the engine of aircraft and boats and ships at present, and among the steam turbine of electric power, petrochemical industry, compressor.
The grooved honeycomb is a kind of special honeycomb seal structure (as shown in Figure 3), and its welding operation space d is no more than 10mm usually.Before the soldering of grooved honeycomb, need to carry out the resistance tack welding, the electrode of existing honeycomb resistance tack welding is comprised of copper alloy top electrode bar and copper alloy electrode plate, because the welding operation space of grooved honeycomb is little, thereby the thickness that inserts the copper alloy electrode plate that welds the space is limited, causes the copper alloy electrode plate usually will deform after using the 1-2 time-of-week.Can cause the tack welding degradation after the distortion of copper alloy electrode plate, tack weld can be thrown off in soldering heating process, causes the joint clearance of brazing to become large, finally causes a soldering qualification rate very low, generally is no more than 40%.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved grooved honeycomb resistance tack welding electrode special is provided, with the problem on deformation of solution battery lead plate, thus the quality of raising grooved honeycomb seal structure tack welding.
Grooved honeycomb resistance tack welding electrode special described in the utility model, comprise copper alloy top electrode bar and stainless steel electrode plate, described stainless steel electrode plate surface is coated with alcu alloy film, and described copper alloy top electrode bar is fixed on stainless steel electrode plate one end that is coated with alcu alloy film.
Grooved honeycomb resistance tack welding electrode special described in the utility model, the thickness of its stainless steel electrode plate is 4mm～6mm, and width is 20mm～25mm, and the degree of depth of the groove in length and part between cellular sandwich and outer cellular sandwich is complementary.
The thickness of the alcu alloy film that grooved honeycomb resistance tack welding electrode special described in the utility model, its stainless steel electrode plate surface coat is 0.1mm～0.3 mm.
The utlity model has following beneficial effect:
1, the battery lead plate due to electrode described in the utility model is the composite construction that corrosion resistant plate and alcu alloy film form, thereby not only efficiently solves the problem on deformation of battery lead plate, and it has good electric conductivity.
2, test shows, use electrode described in the utility model, the quality of grooved honeycomb seal structure tack welding obviously improves, and one time the soldering qualification rate can reach more than 90%.
