虚拟焊接仿真系统允许焊接操作者在进行实际焊接之前,利用仿真系统充分对焊接动作进行单独或多种组合训练,可以极大提高操作者的业务水平。本文介绍虚拟焊接系统中主要的功能模块,对虚拟焊接仿真系统进行分类划分,分析并总结各种焊缝形状视觉模拟技术的优缺点,最后指出虚拟焊接仿真系统未来的研究方向。

英文摘要：

Welding simulation allows welders to well practice and hone their skills by alone or combinations for welding training.Welding simulation is shown to significantly improve the results of actual procedures.This paper firstly introduces simultaneously main modules of welding simulation.Secondly,it classifies the current of the virtual welding simulation system,focuses on force feedback-welding simulation system and then summaries merit and demerit of seam visual simulation technology of welding simulation system.Finally,it confirms the development direction of welding simulation system in the future.
