Abstract

The utility model relates to a special welding wire for coiled nails. The basal body of the special welding wire for coiled nails is a low-carbon steel wire. The external surface of the low-carbon steel wire is coated with a tin layer whose thickness is 1.0-3.5 mu m. The external surface on the surface of the tin layer is coated with a brilliant copper layer whose thickness is 0.5-2.0 mu m. The utility model has the advantages of good welding performance and high oxidation resistance. In the coiled nails produced with the special welding wire for coiled nails, the connection between steel nails and welding wires is firm; when no used, the steel nails can not be easily disengaged from the welding wires; when the emitted by a nail gun, the steel nails can be easily disengaged from the welding wires.

Description

Special welding wire for coiled nail

The utility model relates generally to a kind of section bar, specifically relates to a kind of volume nail and produces special welding wire.

In building industry, ail gun often uses the volume nail to launch steel nail continuously and injects woodwork, to enhance productivity.This volume nail is with two mutual substantially parallel welding wires when producing, and makes itself and steel nail axis be certain inclination angle and is welded in successively on the single steel nail, by welding wire steel nail is connected one by one and pulls together and be rolled into plate-like.Fig. 1 schematically shows the volume nail that is rolled into plate-like, and Fig. 2 schematically shows the welding wire of volume nail and the annexation between the steel nail.Steel nail is connected under non-working condition with connection request between the welding wire should be firm; When nailing, should be easy between steel nail and the welding wire throw off.

Now the steel nail of usefulness with in, mild steel makes, welding wire then adopts copper facing outside the mild steel wire.This known gage of wire is usually between 0.55～0.8mm, because of the only general plating layer of copper of its outer surface, welding wire helps the weldering ability, welding performance is low, and the welding wire surface oxidation resistance is poor, easily oxidation deterioration, influence welding quality, make bonding strength reduction between steel nail and the welding wire, steel nail easily comes off when not using, and influence is used.

The purpose of this utility model is to provide a kind of good welding performance, and the volume nail that is difficult for oxidation deterioration is produced special welding wire.

The technical solution that realizes the utility model purpose is as follows:

A kind of volume nail special welding wire, its matrix is a mild steel wire, is coated with one deck tin at the outer surface of described mild steel wire, is coated with one deck bright copper at the outer surface of described tin layer.

The advantage of volume of the present utility model nail special welding wire is a good welding performance, and oxidation resistance is strong, with being connected firmly difficult drop-off when not using between the steel nail of the volume nail of its production and the welding wire.

The utility model volume nail is produced other details of special welding wire can be cheer and bright by reading the embodiment that hereinafter encyclopaedizes in conjunction with the accompanying drawings, wherein:

Fig. 1 is the volume nail schematic diagram that is rolled into plate-like;

Fig. 2 is the welding wire of plate-like volume nail shown in Figure 1 and the annexation schematic diagram between the steel nail;

Fig. 3 is the schematic cross section of the utility model volume nail special welding wire.

With reference to Fig. 1～Fig. 3.Steel nail among the figure in the sequence number 1 expression volume nail, 2 expression volume nail special welding wires.When making the volume nail, with spot welding steel nail 1 is connected with welding wire 2 and pulls together.Fig. 3 is the schematic cross section of the utility model volume nail special welding wire.Wherein sequence number 21 is represented the mild steel wire matrixes.Mild steel wire 21 is that the employing phosphorus content is 0.05%～0.1% mild steel wire.Outer surface at matrix 21 plates the tin layer 22 that a layer thickness is 1.0～3.5 μ m earlier, and then plates the bright copper layers that a layer thickness is 0.5～2.0 μ m at the outer surface of tin layer 22.Yin Xi has good welding performance, thereby combines firmly with mild steel wire matrix 21, in the time will rolling up nail special welding wire 2 and be welded on the steel fixed 1, also be easy to in, the steel nail 1 made of mild steel is welded together, thereby make welding wire 2 and steel nail 1 firmly welded together.Bright copper coating 23 conducts electricity very well, and is difficult for oxidation, helps welding.

Claims
