Our two-stage automatic welding technology is designed to achieve superior weld quality and high process stability for metal hose assemblies, especially in demanding industrial applications.
The system is typically configured with automatic TIG (GTAW) welding, providing precise heat control and consistent weld penetration for thin-wall corrugated hoses.
The metal corrugated hose is automatically welded to the fitting, forming a stable semi-finished assembly with accurate alignment and controlled weld quality.
After the braid and neck ring are installed, a final automatic welding process is performed to complete the hose assembly, ensuring sealing integrity and structural reliability.
This process represents one of the highest welding standards currently available in the industry, offering:
Thanks to its consistent weld quality and oxidation-free internal surfaces, this automatic welding process is especially suitable for high-pressure metal hose welding and applications with strict quality requirements.
This technology is widely used where burr-free internal welding, high pressure resistance, and long service life are critical.
Traditional metal hose welding typically follows a sequence in which the seal weld is completed first, followed by the fitting weld. This method is still commonly used by many metal hose manufacturers.
However, for industries with much higher quality requirements—such as semiconductor manufacturing, medical, and defense applications—a different approach is increasingly preferred.
In this two-stage automatic welding process, the corrugated hose and fitting are welded together first without the braid. The braid and collar are then assembled, followed by a final automatic welding step.
This process is widely adopted in high-end manufacturing applications to achieve superior weld consistency, cleaner internal surfaces, and higher reliability under demanding operating conditions.
This two-stage welding technology is implemented on automatic welding machines specifically designed for metal hose assembly.
This two-stage automatic welding technology is available on MecaNext automatic welding systems for metal hose manufacturing.

Compatible with stainless steel and high-alloy materials
Designed for high-pressure and vibration-resistant hose applications
Enables oxidation-free and burr-free internal weld quality
Supports stable, repeatable production in automated manufacturing environments
Compared with manual welding, automatic welding ensures stable heat input, consistent weld penetration, and repeatable quality, especially for thin-wall corrugated hoses where manual welding can easily cause burn-through or internal defects.
Automatic welding also improves production efficiency and reduces dependence on operator skill, making it ideal for standardized, high-quality hose manufacturing.
