Introduction
Interpretation of the core content of the standard
GB/T41113-2021 stipulates the systematic requirements for the skill assessment of brazing personnel, which mainly includes the following technical elements:
| Assessment dimensions | Scope of recognition | Change requirements |
|---|---|---|
| Brazing methods | 11 types of methods such as flame/induction | Method changes require re-assessment |
| Parent material group | Grouped according to ISO/TR15608 | Supplementary examination is required for cross-group |
| Joint type | 4 categories including lap/butt joint/T-type | Type extension needs to be tested |
Detailed explanation of key technical requirements
1. Assessment process
Skill assessment needs to be verified by welding and testing of standard test pieces:
- Test piece welding needs to be completed under the supervision of the examiner
- Visual inspection and at least one additional test (ultrasonic/radiographic/peeling, etc.) must be carried out
- Deficiency assessment is based on Class B standard of GB/T33219
2. Certificate management
Qualification certificates adopt a 3+3 years cycle mechanism:
- Initial validity period is 3 years
- Enterprises need to confirm their continuous operating capabilities every 6 months
- For extension, quality certification documents for the past three years must be provided.
Implementation suggestions
Enterprise application solutions
Manufacturing enterprises are advised to establish the following management mechanisms:
- Establish a welder skill matrix to clarify the range of approved parameters for each position
- Develop an annual review plan to ensure the validity of the certificate
- Set up special assessments for special materials (such as nickel-based alloys)
Technology evolution analysis
Compared with ISO13585:2012, this standard has the following major enhancements:
- Add new methods such as vacuum brazing
- Refine the cross-approval rules for parent material groups
- Strengthen process supervision requirements
