Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding wire production, and particularly relates to a non-copper-plated solid welding wire production system and method. BACKGROUND

[0002] With the increasingly stringent environmental requirements in China, non-copper-plated welding wire without acid and alkali in the production process is bound to replace copper-plated welding wire.

[0003] Compared with traditional copper-plated welding wire, non-copper-plated welding wire has the advantages of strong rust prevention, stable arc, small spatter, small smoke toxicity and small pollution, and is the development direction of welding materials in the future. However, the raw material wire rod is easily rusted and corroded in the air, and the oxide layer will cause slag inclusion and porosity in the weld, which seriously affects the welding performance. Therefore, during the production of non-copper-plated welding wire, how to remove the oxide layer to achieve a smooth and scratch-free surface of the welding wire is the core link of welding wire production.

[0004] In order to solve the problem of the influence of the oxide layer on the welding performance, the common method in the existing welding wire production is to perform rust removal treatment on the surface of the steel wire, that is, to remove the oxide scale formed on the surface of the steel wire by physical or chemical methods. The commonly used chemical rust removal method is to immerse the steel wire in hot hydrochloric acid of a certain concentration for pickling, so as to remove the rust stains and oxide scale on the surface of the steel wire. However, hydrochloric acid is a volatile acid, especially in the heated state, the volatilization is more serious, which pollutes the production environment of the steel wire and affects the health of the operators. At the same time, the used waste acid liquid must be treated before being discharged, otherwise it will cause environmental pollution. Therefore, at present, a physical rust removal method for non-copper-plated welding wire is needed. SUMMARY

[0005] In view of the above technical problems, the application provides a non-copper-plated solid welding wire production system, which can produce non-copper-plated welding wire with a smooth and scratch-free surface by a physical method, and avoids the environmental and safety problems of chemical rust removal methods.

The method adopts a physical rust removal method, uses a spiral spring brush and a thousand-leaf wheel to process the welding wire, so that the welding wire is more uniform and smooth, the problem of pickling rust removal is avoided, an acid pickling tank does not need to be built, the space occupation is small, the cost is low, the pollution to the environment and the harm to the workers are reduced, and the method is more environmentally friendly and safe.
