What is the term used when a metal plate is penetrated with an oxyfuel cutting torch?

The term "pierce" is used when a metal plate is penetrated with an oxyfuel cutting torch. This terminology specifically refers to the action of creating an initial hole or opening in the material before continuing with the cutting process. Piercing involves the controlled application of heat from the torch, allowing the metal to melt and be removed, thereby forming an entry point that can then be further cut or shaped as needed.

In the context of welding and cutting, this initial penetration is crucial for starting the operation efficiently and accurately. The use of the term "pierce" thus accurately captures the technique involved in starting a cut through a metal workpiece, differentiating it from actions that might imply a different cutting methodology or result.
