PLASMA ARC TORCH PROVIDING ANGULAR SHIELD FLOW INJECTION |
摘要 |
<p>Plasma arc torches described herein include a torch tip with an improved nozzle that provides angular shield flow injection. In particular, the nozzle provides angular/conical impingement of a fluid (e.g., a shield gas) on an ionized plasma gas flowing through a plasma arc torch. Some of the torch tips described herein include a nozzle with a conical external shape combined with a shield with complementing internal geometry to form the angular fluid flow. As a result, a plasma arc torch including the improved nozzle have the benefits of a stabilized ionized plasma gas flow together with enhanced nozzle cooling and protection from reflecting slag during torch use.</p> |
