This standard JB/T 56100-1999 specifies technical requirements, sampling, test methods, and inspection rules for the quality grading of hardfacing electrodes. Products are classified into three grades (qualified, first-class, superior) based on external quality, internal quality, and process performance. External quality assessment includes 18 items such as eccentricity, moisture resistance, and coating strength. Internal quality focuses on deposited metal chemical composition and hardness. Process performance requires stable arc and good weld formation. It applies to quality grading of surface wear-resistant hardfacing electrodes.
