2026 New ZTRFM High Precision Seam Welded Square & Rectangular Tube Making Machine

2026 New High-Precision Seam-Welded Square & Rectangular Tube Making Machine

High-Speed Seam Welding Solution for Square and Rectangular Tubes

The 2026 New High Precision Seam Welded Square & Rectangular Tube Making Machine from CANGZHOU ZHONGTUO ROLL FORMING MACHINERY CO., LTD is designed to meet the growing demand for high-efficiency, high-precision tube welding in modern steel fabrication plants.

By combining double-sided synchronous welding, a rigid mold-fixing structure, and advanced CO₂/MIG welding technology, this machine helps manufacturers increase output, reduce labor costs, and maintain consistent weld quality.

Machine Overview

This seam-welded tube-making machine is specifically developed for square and rectangular steel tubes that require strong, clean, and uniform weld seams.

Instead of traditional single-sided welding, the machine adopts dual welding guns on both sides, allowing simultaneous welding. As a result, production efficiency is significantly improved while welding deformation is minimized.

Moreover, the mold-fixed welding structure ensures that every tube remains accurately positioned throughout the welding process.

Key Advantages of the Seam-Welded Tube Machine

Double-Sided Synchronous Welding

The machine uses two welding guns on each side, working at the same time. This design:

• Shortens welding time dramatically
• Improves seam strength and symmetry
• Ensures stable and repeatable welding quality

High Precision Mold Fixing Structure

Thanks to the customized welding mold:

• The tube is firmly clamped during welding
• Weld seams remain straight and consistent
• Dimensional accuracy is guaranteed

Powerful CO₂ / MIG Welding System

To meet industrial production demands, the machine is equipped with:

• Six sets of 350A CO₂/MIG welding machines
• Welding length range from 500 mm to 3500 mm
• Stable arc performance for continuous operation

Fully Customized Manufacturing

As a direct manufacturer, Zhongtuo designs and builds each machine according to:

• Tube size and profile requirements
• Welding length and production capacity
