Abstract
The present invention relates to a method for welding steel plates with an organic coating. Holes are drilled in two positions on an upper steel plate with an organic coating, and a welding nail in the shape of a round table is inversely arranged in each hole; the center of the end surface of the round table has a cone, and the welding nail is arranged below a welding electrode; a welding machine is charged, and the welding electrode boosts voltage so that the welding nail are the upper steel plate with an organic coating are welded together; a lower steel plate with an organic coating is arranged below the upper steel plate with an organic coating; the welding machine is charged, and the welding electrode boosts the voltage so that the cone on the end surface of the welding nail penetrates through the coating of the surface of the lower steel plate with an organic coating, and the cone on the end surface of the welding nail and the lower steel plate with an organic coating are welded together. By adopting the present invention, the thickness of the upper steel plate with an organic coating is not limited, and the upper steel plate with an organic coating and the lower steel plate with an organic coating are firmly welded; the coating damage of the decorative cover of the lower steel plate with an organic coating is not obvious.
Description
Belong to the welding method between steel plate with organic coating.
Steel plate with organic coating surface coated one deck organic coating.Because the insulating properties of organic coating, make the welding between the steel plate with organic coating surface become difficult, must remove the coating of desiring weld and just can carry out this place's welding, as the described a kind of dot welding method of GB2096039A (Fig. 1), give the coating of removing earlier on welding electrode and the organic coating plate institute contacting point surface of steel plate, have at another place of contacted steel plate with organic coating by pair of conductive clamp and conduction connecting band and two welding electrodes and form the galvanic circle, when the welding electrode energising, after the pressurization, two steel plate with organic coating are spot-welded together, first that welds can form a galvanic circle with second welding electrode of locating, after the energising, its heat can destroy the coating at the second solder joint place, welds second point.This method complex procedures, as weld the steel plate of two-sided coated coating, need to remove the coating of welding electrode and steel plate with organic coating contacting point, and the coating damage of weld steel plate with organic coating venner is serious.
Purpose of the present invention is in order to overcome the shortcoming of said method, a kind of steel plate with organic coating that is applicable to single, double coated is provided, need not to remove the coating of solder joint place surface of steel plate, simple to operate, be connected firmly the method for the also unconspicuous welding steel plate with organic coating of venner coating damage.
The present invention welds the method for steel plate with organic coating, and two steel plate with organic coating are welded together, and last steel plate with organic coating thickness is h

Two weldering nails, 4 conical end are put into two holes 5 of organic coating plate 2 downwards respectively, the condenser discharge welder charging, 4 pressurizations of welding electrode 1 butt welding nail weld together the hole of weldering nail 4 and last steel plate with organic coating 2 along its ring-type contacting point; To descend again steel plate with organic coating 3 be placed on steel plate with organic coating 2 below, the condenser discharge welder charging, 4 pressurizations of welding electrode 1 butt welding nail, circular cone tip on weldering nail 4 end faces punctures down the organic coating on the steel plate with organic coating 3, weld together with following steel plate with organic coating 3, so far, steel plate with organic coating 2,3 is connected in together.
Adopt the present invention to connect two steel plate with organic coating, technology is simple, and the thickness of last steel plate with organic coating is unrestricted, and firm welding is all welded with upper and lower steel plate with organic coating, and the coating damage of following steel plate with organic coating venner is not obvious.
