Welding Carriage
Portable automatic welding carriages for fillet welding, butt welding, rail-guided welding, weaving welding and long seam welding applications. Designed to improve welding consistency, reduce operator fatigue and support practical welding automation in workshops and field fabrication.
Portable Welding Automation for Consistent Weld Quality
A welding carriage is a compact automatic travel unit designed to move a welding torch along a controlled path. It helps operators maintain stable welding speed, consistent torch angle and repeatable weld bead quality, especially during long welds or repetitive welding work.
HALDEN welding carriages are available in multiple configurations, including mini welding carriage, standard fillet welding carriage, intermittent welding carriage, two-torch carriage, swing-type carriage and rail-guided welding carriage.
These machines are suitable for fabrication workshops, shipbuilding, pressure vessel production, tank welding, structural steel, general engineering and welding automation upgrades.

Swing Type Automatic Welding Carriage
The swing type welding carriage is designed for welding applications that require controlled oscillation. It helps improve bead width control, sidewall fusion and weld appearance when weaving movement is needed.
Oscillation Control
Supports multiple oscillation modes with center movement and adjustable swing movement.
Adjustable Dwell Time
Left and right dwell time adjustment helps control fusion at both sides of the weld bead.
Portable Structure
Approximate weight is 10 kg including oscillator, making it suitable for portable welding automation.
Ultra-Light Welding Carriage
The ED-MIC ultra-light welding carriage is designed for automatic horizontal fillet welding. With a compact structure, light weight and simple operation, it is suitable for operators who need a portable welding automation tool for repetitive welding work.

Applications
HALDEN welding carriages are suitable for industries and applications that require stable long welds, repeatable welding movement and improved operator efficiency.
How to Choose the Right Welding Carriage
The correct welding carriage should be selected according to the weld type, welding position, required travel speed, workpiece shape, torch adjustment range and whether rail guidance or magnetic traction is preferred.
For Basic Fillet Welding
Choose a standard or mini fillet welding carriage for simple, portable and repetitive welding tasks.
For Wider Beads or Oscillation
Choose a swing-type carriage when weaving movement, dwell time adjustment or bead width control is required.
For Guided Long Seam Welding
Choose a rail welding carriage when more stable travel guidance is needed over longer welds.
Frequently Asked Questions
What is a welding carriage?
A welding carriage is a portable automatic travel device used to move a welding torch along a controlled weld path. It helps improve welding consistency and reduce manual welding fatigue.
Is a welding carriage the same as a welding oscillator?
No. A welding carriage controls torch travel along the weld path, while a welding oscillator controls side-to-side or back-and-forth torch movement. Some welding carriages can be equipped with oscillation functions.
What welding applications are suitable for welding carriages?
Welding carriages are suitable for fillet welding, butt welding, long seam welding, tank welding, shipbuilding, pressure vessel fabrication, structural steel and general workshop welding automation.
What information is needed for quotation?
Please provide welding type, weld position, workpiece material, plate thickness, weld length, torch type, required travel speed, power supply and whether weaving or rail guidance is needed.
Need a Welding Carriage for Your Workshop?
Tell HALDEN your welding position, weld type, workpiece size, torch requirement and automation goal. We will recommend a suitable welding carriage model for your application.
