AI Summary AI generated
This standard JB/T 56101-1999 specifies the technical requirements, sampling, test methods, and inspection rules for product quality grading of cast iron welding electrodes. Products are classified into three grades: qualified, first-class, and superior, evaluated based on external quality (e.g., eccentricity, coating strength), internal quality (chemical composition of deposited metal), and process performance (arc striking, restriking). It provides a unified basis for manufacturing and inspection of cast iron welding electrodes.
本标准JB/T 56101-1999规定了铸铁焊条产品质量分等的技术要求、抽样、试验方法和检验规则。产品分为合格品、一等品和优等品三个等级，从外在质量（如偏心度、药皮强度等）、内在质量（熔敷金属化学成分）和工艺性能（引弧、再引弧等）三方面考核。标准适用于铸铁焊条的质量分级，为制造和检验提供了统一依据。

本标准规定了铸铁焊条产品质量等级的技术要求、抽样、试验方法及检验规则等内容。
铸铁焊条的产品质量分为合格品、一等品和优等品三个等级，按其外在质量、内在质量和工艺性能三个方面进行考核。
合格品、一等品和优等品焊条均应引弧容易，在焊接过程中电弧燃烧稳定，不应有过大飞溅。
每批焊条由同一批号焊芯、同一批号主要涂料原料，以同样涂料配方及制造工艺制成。
优等品和一等品以一次检验为准，不允许复验。
This standard specifies the technical requirements, sampling, test methods, and inspection rules for the product quality grades of cast iron welding electrodes.
The product quality of cast iron welding electrodes is divided into three grades: qualified product, first-class product, and superior product, assessed based on external quality, internal quality, and process performance.
Qualified, first-class, and superior grade electrodes shall all be easy to strike an arc, have stable arc combustion during welding, and shall not have excessive spatter.
Each batch of electrodes is made from the same batch of core wire, the same batch of main coating materials, and using the same coating formulation and manufacturing process.
Superior and first-class products are subject to a single inspection and are not allowed to be re-inspected.
