Lincoln Electric has a new virtual reality training system to use for training welders. From what little I have ever welded, it looks fairly realistic. I wonder how the increased availability of this kind of technology will help people learn to weld.

This video shows what the student sees in the construction environment on the VRTEX™ 360. The student first looks around the environment and then proceeds to weld with the GMAW short arc welding process in the 2F position. Half way down the weld a long CTWD is used and porosity can be seen in the finished weld.
