Featured high-efficiency Plasma Transferred Arc (PTA) welding and plasma cladding equipment configured for heavy manufacturing plants in Jubail, Yanbu, and Riyadh.
Saudi Arabia’s aggressive industrial expansion under Vision 2030, particularly in downstream oil & gas, chemical processing, phosphate mining, and desalinization, demands extreme-performance metallurgy. Equipment operating in these environments is subjected to high pressures, friction with abrasive minerals, and contact with highly corrosive media (containing H2S, CO2, and chloride ions).
Plasma Transferred Arc (PTA) welding has emerged as the premier technology to apply thick, high-performance wear-resistant coatings (such as Tungsten Carbide matrixes, Stellite cobalt alloys, and Inconel nickel-based alloys). PTA provides superior bonding strength compared to traditional thermal spray techniques and produces significantly lower dilution rates than standard arc welding processes.
Combining state-of-the-art Chinese engineering with custom automation setups designed to pass the stringent inspection criteria of major Saudi operators.
We build tailor-made PTA equipment featuring multi-axis CNC positioners, intelligent robotic control systems, and localized user interfaces suitable for operators in the Middle East.
Our manufacturing facility in China leverages robust component supply chains, enabling us to deliver world-class PTA technology at a fraction of the cost of European competitors, with rapid delivery times.
Our processes support the requirements for ASME Sec IX, ASTM G65 wear tests, and chemical composition analysis, ensuring that parts cladded with our machines meet Aramco and SABIC specifications.

| Feature / Parameter | PTA Cladding (Plasma Transferred Arc) | Laser Cladding (LMD / DED) | Traditional GMAW / GTAW Hardfacing |
|---|---|---|---|
| Dilution Rate | Low (3% – 8%) | Ultra-Low (1% – 3%) | High (15% – 30%) |
| Metallurgical Bond Strength | Excellent (Fused/Welded) | Excellent (Fused/Welded) | Good (But high mixing with substrate) |
| Deposition Rate | High (2 - 12 kg/hr) | Medium (0.5 - 4 kg/hr) | High (2 - 8 kg/hr) |
| Heat Affected Zone (HAZ) | Moderate | Very Small / Minimal | Large (Risk of distortion) |
| Initial Capital Investment | Moderate (Highly cost-efficient) | High | Low |
| Powder/Alloy Flexibility | Extreme (Tungsten Carbides, Cobalt/Nickel base) | High (Requires specific grain sizes) | Limited to wire specifications |
We provide specialized systems built specifically for core Middle Eastern industry challenges.
Gate valves, ball valves, and control valve seats in high-temperature, sour gas environments require Cobalt-base (Stellite 6) alloy overlays. Our automatic valve hardfacing machinery delivers flawless, non-porous cladding.
Downhole components like stabilizers, mud motors, and drill collars face severe abrasion from sand and hard rock formations. Applying Tungsten Carbide composites using PTA protects these expensive assets.
Saltwater pumps and impellers suffer from cavitation and erosion-corrosion. PTA cladding with duplex stainless steel or superalloys protects fluid pathways and extends pump lifespan by 300%.

The PTA Welding Valve Application Guide is not just a process choice for valve manufacturers facing high wear, high corrosion, and high-temperature erosion working conditions, but also a key path to improving product competitiveness. As industries such as petrochemical, gas, and power expand, obtaining standard qualification is essential.
In industries such as mining, cement, power generation, steelmaking, chemical processing, and biomass energy, screw conveyors are often regarded as auxiliary equipment. However, maintenance data shows that they are among the most frequent causes of unplanned production downtime. Protecting flights with PTA hardfacing extends their service life significantly.
In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. One of the most critical factors that directly affects overlay performance is the dilution rate. Keeping dilution below 8% is vital to ensure maximum carbides remain in the matrix.
