Embodiment Construction

[0009] Such as Figure 1 As shown, the wire guide tube (7) is installed on the welding torch support (4), the welding wire (3) passes through the wire feed wheel (1), enters the wire guide tube (7), and the two flux belts (8) pass through the feed wheel ( 2) Enter the belt guide tube (6). Such as figure 2 b. figure 2 As shown in c, the cross-sections of the two plate-type conductive nozzles (9a) are both wedge-shaped surfaces, and they are respectively installed on the welding torch support (4) through spring plates (5). Such as figure 1, figure 2 As shown in a, a through slot (9c) through which the welding wire (3) passes is opened on the plate-type conductive nozzles (9a, 9b). Such as figure 1, figure 2 b. figure 2 As shown in c, the two flux tapes (8) are separated by the wedge-shaped surface of the plate-type conductive nozzles (9a, 9b) after passing through the tape guiding tube (6). Such as figure 1, figure 2 As shown in b, 2c, two ceramic sheets (10) are embedded in t...

Abstract

The invention relates to a solder electric arc weld gun, used in electric arc weld. It is purposed to adjust the feeding speed of solder band and solder wire, relative melt amount, and limit the electric arc to improve its energy density and stability. Wherein, it wire tube (7) is mounted on the weld gun base (4); solder wire (3) via feeding wheel (1) is fed into wire tube (7); two solder bands (8) via feeding belt wheel (2) are fed into band guide tube (6); the sections of two sheet conductive nozzle (9a) are both the wedge surfaces, which via spring blade (5) are mounted on the weld gun base (4); the sheet conductive nozzles (9a, 9b) have the through grooves (9c) of solder wire (3); two solder bands (8) vi band guide tube (6) are separated by the wedge surfaces of sheet conductive nozzles (9a, 9b).

Description

Technical field [0001] The invention relates to welding processing equipment, in particular to a device used for arc welding. Background technique [0002] In order to obtain a good welding joint during welding, on the one hand, a stable welding arc and a reasonable droplet transition shape are required; on the other hand, alloying elements need to be added to control the performance of the welded joint by controlling the metallurgical reaction. For this reason, many welding methods with added powder (containing alloy elements) have been developed, such as electrode arc welding in which the powder is pressure-coated on the surface of the light welding wire for welding. Since the electrode can not achieve continuous welding, it was later developed to achieve continuous welding. In addition, the flux-cored wire arc welding in which powder is added to the tubular welding wire to achieve continuous welding has been developed. However, these welding methods have a fixed ratio of the a...
