摘要

为了满足新工科教育对培养新型工科人才的需求，提高材料成型与控制工程（焊接）专业的教学质量，夯实学生的学科理论基础，培养学生的专业理论分析能力，以焊接热过程数值分析课程为研究对象，开展了项目式教学探索。将焊接热过程理论与流体动力学（CFD）理论和工具软件融合起来，开展了融合理论学习与数值模拟试验为一体的项目式教学探索。以典型熔焊工艺钨极氩弧焊熔池为分析对象，设计了熔池数值模拟模型，分别从材料属性、焊接参数、热源模型等方面分析了熔池热过程，完成数据分析和理论探讨。基于项目式教学模式，加强学生与教师的全过程互动，驱动学生自主学习，培养学生利用先进工具软件解决工程实际问题的能力，有利于培养具备厚实理论基础和实践能力的焊接人才。

Abstract

In order to meet the needs of new Engineering education for cultivating new engineering talents

improve the teaching quality of materials forming and control engineering (welding) majors

consolidate students' theoretical basis in the subject

and cultivate students' professional theoretical analysis capabilities

the project-based teaching research was conducted to reform the course on numerical analysis of welding thermal processes. Integrating welding thermal process theory with fluid dynamics (CFD) theory and tool software

a project-based teaching exploration that integrates theoretical learning and virtual simulation experiments was conducted. Taking the Gas Tungsten Arc Welding molten pool as the analysis object

a numerical simulation model of the molten pool was designed

and the thermal process of the molten pool was analyzed from the aspects of material properties

process parameters

heat source model

etc.

and data analysis and theoretical discussion were completed. The project-based teaching strengthens the whole-process interaction between students and teachers

drives students' to learn independently

and cultivates students' ability to use advanced tools and software to solve practical welding engineering issues

which is conducive to cultivate welding talents with a solid theoretical basis and practical ability.
