Welding process in roll forming machine

In roll forming machines, welding is often integrated into the production line to join metal strips or sections into continuous lengths. Common welding methods used include:

1. High-Frequency (HF) Welding

A fast and efficient process that uses high-frequency current to heat and fuse the metal edges, ideal for producing longitudinal seams in tubes or closed profiles.
2. Laser Welding

Offers high precision with minimal heat distortion, suitable for thin materials and high-speed roll forming applications requiring superior weld quality.
3. MIG (Metal Inert Gas) Welding

A versatile arc welding method that uses a consumable wire electrode, often employed for thicker materials or structural components.
4.TIG (Tungsten Inert Gas) Welding

Provides clean, high-quality welds with excellent control, typically used for stainless steel or non-ferrous metals in precision applications.
5. Resistance Welding

Includes spot or seam welding, where electric current and pressure create localized welds, often used for overlapping sheet metal joints.

The choice of welding method depends on material type, thickness, production speed, and desired weld strength, ensuring seamless integration within the roll forming process.

➢Motor Power: 7.5 KW
➢Bottom frame: 350*175*8mm H steel
➢Frame panel: Thickness 20mm
➢Driven type: Chain
Laser welding
Laser welding has concentrated energy, a small heat-affected zone, and weld strength close to that of the parent material, reducing the risk of cracking.
Welding Device
No welding slag, no oxidation: Inert gas protects the welding area, the weld is smooth, and the subsequent grinding process is reduced.
No-stop cutting device
In the continuous production process, the traditional cutting method requires stopping to change materials or make adjustments, while non-stop cutting allows the cutting to be completed while the production line is running at full speed, greatly reducing production interruptions and improving equipment utilization.
Welding Pipe&Tube
Applicable to a variety of pipe materials: can produce round pipes, square pipes, rectangular pipes, special-shaped pipes, etc. to meet the needs of different industries.
