Abstract

Based on Response Surface Methodology (RSM), the correlations of welding technological parameters as electric current, welding speed, and root gap with weld bead geometry characteristics including bead width, over-thickness, and penetration were established in thin plate single-layer single-pass welding process. Through the desirability optimal process, the most appropriate welding technological parameters were determined. Then welded joints have excellent elongation and low-temperature impact toughness. The inclusion is demonstrated by the fatigue performance test of butt welds produced by welding technological parameters. The fatigue strength of the butt weld is significantly higher than the demand in some steel structure design specifications. This increase of 21 %–58 % is represented. This method suggested in the paper provides a new optimization idea of welding technological parameters and there is great significance for the development of high-quality welding process.

基于响应面法的薄板焊接工艺参数及力学性能优化

基于响应面法（RSM），建立了薄板单层单道焊接工艺中电流、焊接速度、焊根间隙等焊接工艺参数与焊头宽度、过厚、焊透等焊缝几何特征之间的关系。通过优选工艺，确定了最合适的焊接工艺参数。焊接接头具有优异的伸长率和低温冲击韧性。通过焊接工艺参数对对接焊缝的疲劳性能试验证实了夹杂物的存在。对接焊缝的疲劳强度明显高于某些钢结构设计规范的要求。这是21% - 58%的增长。本文提出的方法为焊接工艺参数优化提供了一种新的思路，对开发高质量的焊接工艺具有重要意义。

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
