The following are the specifications and precautions for galvanized wire in the production of craft wire:

Specifications

Wire diameter: The diameter of galvanized wire usually ranges from 0.5mm to 3mm. For example, 0.8mm, 1mm, and 1.2mm are commonly used in some ordinary protective welded wire meshes. The allowable deviation of wire diameter is generally about ±0.05mm, but specific deviation requirements may vary according to different industry standards and usage scenarios.
Zinc coating thickness: For ordinary environment use, the average thickness of the galvanized layer may be required to reach more than 45μm. For welded wire meshes used in harsh corrosive environments such as seaside and chemical plant surroundings, the average thickness of the galvanized layer often needs to reach more than 80μm.
Tensile strength: Galvanized wire itself should have a tensile strength that meets the requirements. For example, the tensile strength of commonly used low-carbon galvanized wire may be between 300MPa and 500MPa.
Elongation: The wire should have a certain elongation, usually 10%-25%, to ensure that it has a moderate deformation ability without brittle fracture when subjected to external forces.

Precautions

Raw material procurement: Select regular and reputable suppliers and check the quality certification documents provided by them, such as material test reports and galvanized layer test reports, to ensure that the wire diameter, material composition and galvanized quality of the raw materials meet the production requirements. Random inspection of the purchased raw materials should be carried out to check the basic indicators such as wire diameter and galvanized layer appearance.
Production process
- Welding equipment debugging: Before starting production, accurately debug the welding equipment and set appropriate welding current, voltage and welding time parameters according to the wire diameter, mesh size, etc. Regularly check and calibrate these parameters during the production process to ensure the stability of the welding quality.
- Production operation norms: Operators must strictly follow the established production process procedures. For example, in the processes of wire feeding, mesh pulling and welding, ensure the continuity and accuracy of the operations to avoid quality problems such as wire diameter deformation, mesh size deviation and unqualified welding caused by improper human operation. At the same time, operators are required to take safety protection measures and wear corresponding protective equipment.
- Quality inspection: Arrange special personnel to conduct quality inspections on the production line, focusing on checking welding quality, mesh size, wire diameter and other indicators. If problems are found, stop the machine in time for adjustment. For the links with more quality problems, in-depth analysis of the causes should be carried out and corresponding improvement measures should be taken to prevent the occurrence of mass defective products.
Finished product inspection and packaging
- Finished product inspection: Conduct comprehensive inspection or sampling inspection of the produced galvanized wire products according to a certain proportion, and check the galvanized layer quality, welding quality, size specifications and other indicators in detail according to the quality standards. Mark and isolate the unqualified products, and they can be reworked, repaired or scrapped according to the actual situation.
- Packaging protection: When packaging the qualified products, select appropriate packaging materials, such as moisture-proof paper and plastic film. For galvanized wire products that need to be transported over long distances or stored for a long time, take moisture-proof, rust-proof and other protection measures, and mark the product specifications, quantity, production date and other relevant information on the packaging for easy identification and management.
