PTA Welding System

Our PTA Welding System is specifically designed for the harsh operating conditions found in the oil and gas industry. It operates with a welding current of 25 to 350 amperes and a powder feed rate of 1.2 to 7.5 kilograms per hour. The cladding layer achieves a hardness of 38 to 45 HRC, effectively resisting abrasive wear from sand and rock cuttings in crude oil, as well as chemical attack from corrosive media like hydrogen sulfide. We have worked extensively with multiple oil drilling and production companies, accumulating rich experience in downhole tools and surface manifold cladding. All this knowledge has been incorporated into the design of this system.

Preheating Control and Large Workpiece Capacity

 

This system supports coordinated workpiece preheating between 150 and 350 degrees Celsius. This feature is essential for preventing cold cracks when cladding high-alloy steels and nickel-based materials. The system can handle workpieces with a wall thickness of up to 120 millimeters. Its fixture supports a maximum load of 1,500 kilograms, which is sufficient for large drill collars, valve bodies, and casing joints. The dilution rate stays stable between 7% and 12%, ensuring that the high-hardness cladding layer maintains its wear resistance without being weakened by excessive dilution. We support both FOB and EXW trade terms, offering flexible options for our international customers. Our PTA Welding System is built to perform in the toughest environments.

We provide specialized remote process support for oilfield clients using this system. If you encounter any cladding quality issues on-site, such as porosity, cracks, or poor bead formation, you can send us your parameters and photos. Our process engineers will provide an analysis report and adjustment recommendations within 24 hours. We understand that continuity of operations is extremely important in the oil industry. Our goal is to make every PTA Welding System the most reliable partner at your worksite.
