Abstract: Because the welding technology plays an important role in actual industrial production and the requirements for technicians are very strict, the importance of welding practical training is self-evident. Compared with vocational and technical colleges, there are some problems, namely the short teaching cycle and the insufficient teaching equipment, in some undergraduate colleges and universities. The welding practical training, based on the finite element virtual simulation technology, can improve the learning interest of the students, and improve teaching quality. At the same time, the new welding practical training can prevent safety problems caused by unfamiliar operation of the students.

Key words: The finite element software, The virtual simulation, The welding practical training, The practical training teaching
