Embodiment Construction

[0010] The present invention will be further described below in conjunction with drawings and embodiments.

[0011] The welding machine of the invention is matched with a portable IGBT double-wire welding inverter power supply. Such as figure 1 As shown, the portable multi-functional double-wire self-shielded flux-cored welding equipment, 1. Flux-cored wire; 2. Wire clamping mechanism; 3. Portable welding torch body; Power supply 6. Hand-held welding torch head with adjustable wire pitch, 7. Welding double molten pool, 8. Welded steel rail. The welding wire pinching mechanism is an integrated self-shielding flux-cored wire double-wire wire-feeding mechanism with smooth wire feeding. In order to protect the flux-cored welding wire from being crushed and damaged, each wire feed roller has the following figure 2 The U-shaped groove 9 shown. The hose can be connected between the wire feeding mechanism and the gun body of the welding torch, and the flux-cored welding wire pass...

Abstract

The invention discloses a portable multifunctional double-wire self-protecting flux-cored wire welding device, consisting of a welding wire pinching mechanism, a handheld welding gun body and portable IGBT double-wire welding inverted power source. The welding wire pinching mechanism is an integrally-arranged self-protecting flux-cored wire double-wire feeding mechanism which can feed wires smoothly and consists of two pairs of wire feeding wheels and wire feeding tubes. The device has the advantages of portability, high efficiency, strong anti-interference ability, good cooperativity, and the like and ensures stable double-wire welding process, attractive welding line molding and high welding quality.

Description

Technical field [0001] The invention belongs to a welding device, and is especially applied in the field of manufacturing double-wire self-shielding flux-cored wire welding equipment. Background technique [0002] The metallurgical quality of single-wire welding used in the repair of large-scale engineering components is not easy to control and adjust, and the welding repair layer is prone to cracks and other defects. The welding efficiency is low, and it is difficult to meet the needs of efficient welding. In order to solve problems such as cold cracks after welding, double-wire welding with flux-cored wires has been developed. This technology can not only improve work efficiency, but also control stress and deformation. When welding with filament welding, a favorable narrow and long temperature field and bimodal thermal cycle can be formed during twin-wire welding, which can reduce the maximum temperature of the molten pool, reduce the degree of overheating and the width o...
