The automatic elbow cladding equipment for elbows adopts a fully intelligent PLC process control system, which has a variety of operating functions, such as intelligent fully automatic setting function of main process parameters, storage function of main process parameters, etc., which can effectively realize automatic welding of the inner wall of the elbow. Surfacing welding, the operation is smooth and reliable, the flatness after welding is high, and the surfacing welding effect is good.
This equipment can realize cladding welding of variable thickness pipe walls. The cladding width and thickness are adjustable and easy to adjust. It has the characteristics of high efficiency, stability, flexibility, and high degree of automation. It can greatly improve production efficiency and product quality, and reduce production costs. It can reduce the labor intensity of workers, adapt to the inner wall surfacing welding of different types of elbows, and has a wide range of applications.
Xinghe Keer uses fully automatic cladding equipment for surfacing cladding of pipe fittings, flanges, forgings, valve parts and special-shaped parts. Our welding method is called hot wire TIG welding, also known as Gas Tungsten Arc Welding (GTAW). The welding process meets the relevant requirements of ASME IX, NACE, MR0175, API 6A, and API 5LD, also meets different customers’ different requirements for Fe dilution rates.
