Professional interpretation of the test method of laser cladding head for metal powder directed energy deposition equipment for additive manufacturing
1. Standard overview
GB/T 43614-2023 "Test method for laser cladding head for metal powder directed energy deposition equipment for additive manufacturing" stipulates the test requirements and inspection report for laser cladding heads, mainly covering three core performance indicators: spot size, powder spot diameter and light-powder coaxiality.
2. Comparison of standard frameworks
Standard dimensions GB/T 43614—2023 Comparison of international standards Comparison of industry standards Test scope Coaxial light internal powder feeding and optical external powder feeding equipment Additive manufacturing testing standards under the ISO/ASTM framework NF S32-401 and other national industry standards Test methods Hollow probe method, powder weighing method, coaxial imaging method, tooling detection method Combination of non-contact measurement and dynamic analysis Regional standardized test process Technical parameters Spot size accuracy ±5%, powder spot diameter repeatability ±2% International general error control standard Meet the industrial testing standards of various countries 3. Implementation suggestions
Suggestion 1:The selection of test equipment should follow the accuracy requirements of weighing sensors in GB/T7551-2008 to ensure the accuracy of data collection.
Suggestion 2:In the spot size test, special attention should be paid to laser protection measures and the individual protection specifications in GB 39800.1 should be strictly followed.
Recommendation 3: For the light-powder coaxial test, it is recommended to use the test fixture in Appendix D of the standard to ensure the accuracy and repeatability of the measurement.
