Backfire and Flashback in Gas Equipment

Welding, cutting, heating, and straightening are examples of processes which have been done with gas since the beginning of this century (fuel gas and oxygen or air). There are many advantages in using gases for these processes. Among other things, the equipment is very versatile, it is easy to move around and it is relatively inexpensive. These advantages mean that even in the future the combustion processes will have many industrial applications.
