Automated Welding Solutions for Metal Hose Assemblies

When producing metal hoses, the welding process is one of the most critical steps. The right automated welding solution can significantly impact product quality, production efficiency, and long-term reliability. At Mecanext, we understand that one size does not fit all—different welding processes have unique advantages, and we help you choose the best method for your specific hose assemblies and production requirements.

Why Choose Automated Welding for Metal Hoses?

Traditional manual welding is labor-intensive, inconsistent, and heavily reliant on skilled operators. By switching to automated welding, manufacturers gain:

  • Higher efficiency – Faster cycle times and optimized production processes.
  • Stable and consistent welds – Reliable quality across every batch.
  • Flexibility – Solutions adapted to different hose sizes, fittings, and production scales.
  • Lower skill dependency – Even general operators can achieve top-quality welds.

1. Single-Pass Automated Hose Assembly Welding – Corrugated Hose, Braid, Fittings in One Step

Recommended Solution: HF50J Metal Hose Welding Machine(Single-Pass Welding)

The One-Pass Hose Assemblies Welding process streamlines metal hose fabrication by combining the welding of the corrugated hose, braid, collar, and fitting into a single operation.

How it works: 

Instead of separate seal welds and fitting attachment welds, all four components are joined in one continuous TIG weld. This eliminates redundant steps, reduces handling, and maximizes production speed.

Key Benefits

    • Single-step operation – Replaces two conventional welds, saving time.

    • High yield rate (≥96%) – Consistent results even with operators of general skill levels.

    • Clean weld appearance – Smooth, aesthetically pleasing external welds.

    • Oxidation-free interiors – With proper pre-treatment or precision cutting, internal surfaces remain smooth and burr-free.

Applications

Ideal for high-volume metal hose production in industries such as automotive, HVAC, and industrial fluid handling, where speed, repeatability, and quality are critical.

2. Internal & External Automated Hose Welding – Strong, Clean TIG Welds

  • The Internal & External Two-Stage Welding Method is an advanced process delivering exceptional strength, reliability, and internal cleanliness. It is ideal for applications where performance under stress and surface purity are critical. The process is internal autogenous TIG welding, followed by external TIG welding (with or without filler wire).

Recommended Solution: HF50J Metal Hose Welding Machine

How It Works

    • Internal/First Weld: Autogenous TIG welding joins the corrugated hose to the fitting, creating a smooth, burr-free, and oxidation-free internal surface. Visual inspection can be performed after this weld.

    • External/Second Weld: The braid and collar are welded to the hose and fitting using TIG welding, with or without filler wire, depending on design requirements.

Proper pre-treatment ensures optimal weld quality, smooth external appearance, and flawless internal surfaces.

Key Benefits

  •  Clean Surface-Post-processing ensures smooth, burr-free, and oxidation-free internal surfaces, combining mechanical strength and cleanliness.
  • High yield rate (100%) – Consistent results even with operators of general skill levels.

  • Withstands high pressure and intense vibration.

Applications

  • Vacuum Technology / Vacuum Systems

  • Medical Equipment & Devices

  • Food & Beverage Processing

  • Fire Protection Systems / Fire Safety Equipment

  • HVAC Systems (Heating, Ventilation & Air Conditioning)

3. Filler Wire TIG Welding for Hose Assemblies – Flexible Small-batch Production

The Traditional Filler Wire Sealing Welding process is a proven method for batch or small-lot production, offering flexibility and compatibility without requiring component pre-treatment.

  • First Weld: Filler wire sealing welding joins the hose, braid, and collar together.
  • Second Weld: The assembly is welded to the fitting.

Process and Quality

  • Process: TIG welding with filler wire.
  • Quality Considerations: Internal welds may show oxidation, which is typical for filler wire methods, but assemblies remain fully functional and leak-resistant.

Benefits

  • 100% yield rate – Ensures consistent results.
  • Flexible batch production – Ideal for multi-variety, small-lot manufacturing.
  • Compatibility – Works with various hose sizes and standard fittings.
  • Ease of use – No pre-treatment of components required.

Applications

Best for batch production or small-lot manufacturing where multiple hose sizes or fittings are used, and quick setup is required.
