1. Background of standard formulation and analysis of technological evolution
GB/T 43483-2023 "Design Specification for Heavy Machinery Welded Parts" is an important standard formulated based on the summary of many years of welding technology practice experience and the development needs of advanced technologies at home and abroad. With the increasing demand for high-performance and high-reliability welded structures in the heavy machinery industry, the release of this standard provides an important basis for ensuring the safety, economy and sustainability of welded parts.
2. Standard framework comparison table
Standard dimensions Content overview Scope of application Technical requirements Material selection Covering materials such as carbon structural steel and low alloy structural steel, and clarifying the weldability evaluation method Applicable to steel weldments in heavy machinery and components Comprehensive analysis and comparison based on usage conditions and economy Weld strength calculation Provide strength calculation formulas for various forms such as butt joints and fillet welds Design of weldments under different load conditions Consider complex working conditions such as static load, variable load and thermal dynamic load Economical and rational Emphasis on structural optimization, rational use of materials and process improvement Design link of heavy machinery manufacturing enterprises Focus on cost control and quality assurance 3. Material selection and weldability evaluation
Case analysis:In the design of welded parts of heavy machinery, the selection of materials is crucial. For example, in high stress and low temperature environments, steel with good resistance to lamellar tearing performance should be preferred, such as Z-direction steel plates that meet the GB/T5313 standard.
