Description

Technical Field

[0001] This utility model relates to the field of welding wire, specifically an enhanced solid core welding wire. Background Technology

[0002] Welding wire is a metal wire used in welding, either as filler metal or simultaneously as a conductive electrode. In gas welding and tungsten inert gas (TIG) welding, the welding wire serves as filler metal; in submerged arc welding, electroslag welding, and other gas metal arc welding, it acts as both filler metal and a conductive electrode. Currently, commercially available gas-shielded copper-plated solid welding wires have poor overall performance in terms of strength, hardness, and toughness, making them prone to breakage during use and resulting in a short service life that fails to meet market and user demands. Therefore, we have proposed an enhanced solid welding wire. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 An enhanced solid welding wire includes a welding wire core 1, a copper plating layer 3 on the outside of the welding wire core 1, and multiple sets of combustion-supporting flux 6 arranged in a ring around the outside of the copper plating layer 3. An outer layer is provided outside the combustion-supporting flux 6. The welding wire core 1 is made of titanium alloy ingot. This device is installed in the thermal spraying unit of the wire feeder and fed into the welding gun for thermal spraying of the workpiece. Using this solid welding wire, the generated arc becomes a concentrated arc, and a droplet transfer can be reliably achieved during a pulse current period.

[0022] Furthermore, multiple sets of recessed grooves 2 are equidistantly formed on the outer wall surface of the welding wire core 1. The arrangement of multiple sets of recessed grooves 2 can increase the rigidity of the device when it is bent, making it less likely to break.

The recessed groove 2 is attached to the inner wall of the copper plating layer 3. By adding the recessed groove 2, the copper plating layer 3 can be adhered more stably.

[0024] Furthermore, the outer side of the copper plating layer 3 is integrally formed with multiple sets of outer protrusions 5, and the combustion-supporting flux 6 is placed in the gap between two adjacent outer protrusions 5. This allows the combustion-supporting flux 6 to adhere firmly to the outer side of the copper plating layer 3, and the equidistant arrangement allows the combustion-supporting flux 6 to fully support combustion.

[0025] Furthermore, the outer layer includes an alloy layer 7 and a corrosion-resistant and wear-resistant layer. The alloy layer 7 is disposed on the outside of the multiple sets of combustion-supporting flux 6, and the corrosion-resistant and wear-resistant layer is disposed on the outside of the alloy layer 7. By adding the alloy layer 7 and the wear-resistant and corrosion-resistant layer, the solid welding wire can have excellent comprehensive mechanical properties, high strength, and wear resistance, greatly enhancing the overall toughness, plasticity, strength, and hardness of the solid welding wire, and significantly improving the corrosion resistance and oxidation resistance of the solid welding wire.

[0026] Furthermore, the corrosion-resistant and wear-resistant layer includes a corrosion-resistant layer 8 and a wear-resistant layer 9. The corrosion-resistant layer 8 is disposed on the outside of the alloy layer 7, and the wear-resistant layer 9 is disposed on the outside of the corrosion-resistant layer 8.

[0027] Working principle: This device is installed in the thermal spraying unit of the wire feeder and fed into the welding gun to perform thermal spraying on the workpiece.
