How does Neway’s welding expertise support demanding operating conditions?

Specialized Welding Approach

Neway’s welding capabilities are designed specifically for high-temperature, high-stress environments often found in aerospace and aviation, oil and gas, and power generation industries. Superalloy welding is conducted through controlled thermal input to avoid grain coarsening and embrittlement in the heat-affected zone (HAZ). Advanced welding processes—including TIG, laser, and electron-beam welding—are applied depending on alloy type, thickness, and functional requirements. Neway integrates precise welding techniques with engineered filler materials to ensure metallurgical compatibility in alloys such as Inconel, Hastelloy, and Rene.

Resistance to Extreme Environments

For turbine blades, combustor components, and pressure boundaries, Neway applies rigorous welding procedures supported by real-time monitoring to prevent microcrack formation. These welded sections are then reinforced with sequential superalloy heat treatment and hot isostatic pressing (HIP) to enhance grain cohesion, strengthen phase stability, and eliminate porosity. This combination significantly increases fatigue life and creep resistance, which is essential for components undergoing cyclic thermal loads.

To protect critical surfaces from oxidation and hot-gas erosion, Neway applies thermal barrier coating (TBC) after welding, extending service intervals and reducing unplanned downtime.

Welding of Advanced Superalloys

Neway is capable of welding complex nickel-based alloys such as CMSX-10 and high-strength materials like Rene 65, ensuring microstructural stability even under extreme thermal cycling. Precision welding protocols and optimized cooling strategies prevent hot cracking and maintain phase distribution. For critical repairs and refurbishments, Neway adopts tailored welding procedures compatible with parts produced by single crystal casting and directional solidification, allowing components to be restored rather than replaced.

Inspection and Validation

To ensure reliability under demanding operating conditions, welded components undergo advanced non-destructive material testing and analysis, including CT scanning, X-ray, and metallographic evaluation. Dimensional recovery is achieved through precision superalloy CNC machining, ensuring tight tolerances and assembly readiness. Through this end-to-end welding, treatment, and validation process, Neway delivers components that can operate reliably under extreme heat, pressure, vibration, and corrosive media.
