What is Micro Plasma Arc Welding?
Micro Plasma Arc Welding (MPAW) is a high-precision welding method using a contracted plasma arc as the heat source. It belongs to a branch of plasma arc welding (PAW), the working current range is usually 0.1-30 A, the arc is extremely small, so it is called “micro beam”. It is suitable for weld...Read more -
Application of PTAW on PDC Drill Bits
Against the backdrop of accelerated development in deep, ultra-deep, and highly abrasive formations, PDC (Polycrystalline Diamond Compact) drill bits demand enhanced wear resistance and erosion resistance for their cutting wings, tooth seats, and flow channels. ...Read more -
