Introduction
Non-alloy steel and fine grain steel flux-cored welding wire
| Item | Content |
|---|---|
| Standard name | GB/T 10045-2018 Non-alloy steel and fine grain steel flux-cored welding wire |
| Scope of application | Applicable to non-alloy steel and fine grain steel flux-cored welding wire for gas shielded and self-shielded arc welding with a minimum tensile strength requirement of no more than 570 MPa. |
| Main changes | Two chemical composition classifications, NCC2 and NCC3, were added, the low alloy steel welding wire model was reorganized, and the technical requirements and test methods were adjusted. |
Background of Standardization
GB/T 10045-2018 replaces GB/T 10045-2001. The main modifications include:
- Update model division and classification methods
- Add chemical composition classification (NCC2 and NCC3)
- Adjust mechanical properties and technical requirements
- Reformulate test methods and re-inspection rules
Technology Evolution Analysis
Compared with GB/T 10045-2001, the new standard pays more attention to:
- Adapt to the requirements of international standard ISO 17632:2015
- Increase the control of diffusible hydrogen content
- Optimize the classification of welding positions and shielding gas types
- Refine the chemical composition and usage characteristic codes
Implementation suggestions
To ensure the effective implementation of the standard, it is recommended that:
- Manufacturers strictly control the size and surface quality of welding wires
- Users choose appropriate models and shielding gases according to actual needs
- Strengthen the detection and management of diffusible hydrogen content
- Strictly follow the test methods and re-inspection work in accordance with the standards
