Auto-Seam Welding Machines

The lifting straight seam welding machine is designed for welding the longitudinal welding seams of cylindrical barrels. The axial flow fan duct with relatively thick metal plates must use a seam welding machine in the manufacturing process of the duct.
The production line mode or the single machine production mode can be selected according to the production situation！

Seam Welding Machine Description

• The Horizontal Lifting Straight Seam Automatic Welding Machine is a top-of-the-line, high-efficiency solution for welding non-deformable cylinders with a wall thickness ranging from 0.6mm to 3mm. It excels in butt joint longitudinal seam welding of cylinders, flat plates, or square boxes with one end open. Suitable for carbon steel, cold galvanized, and stainless steel materials, it offers the option of argon arc welding (with or without wire filling) or melting electrode gas TIG welding power sources, complemented by a longitudinal seam automatic welding system.
• The machine features a one-piece main shaft with built-in copper bars and split all-copper pressure plates. The main beam can be electrically raised or lowered, facilitating size adjustments of pipe fittings, enhancing feeding speed, and providing robust load-bearing capacity. Welding torch lifting employs pneumatic and truss lifting, ensuring precise positioning.
• The host control system utilizes PLC control for stable and reliable operation. Notable features include adjustable welding table height, an upgraded high-precision external positioning and centering device for improved convenience and durability, and fine-tuning capabilities for the welding torch in vertical, horizontal, left, and right directions.
• The welding torch traveling mechanism utilizes a pneumatic clutch method, enabling quick and accurate positioning without the need for touch screen control. Pneumatic tipping eliminates the need for manual operation. The machine supports continuous integral or segmental welding, offering excellent control precision and stability. TIG welding or MAG welding can be selected based on specific requirements.
• To ensure optimal welding results, the machine incorporates an airbag pressing device with flexible copper plate pressing for enhanced thermal conductivity. A mandrel-inserted bottom spindle, equipped with a safety device, guarantees proper depth of welding fusion. The welding torch is guided by TBI linear guide rail and TBI ball screw, ensuring stable welding performance. The feeding frame has universal travel, while the cantilever features electric lifting, and the welding torch is pneumatically adjustable in height.

Home Page Matters:

• 1. Before using the machine, preliminary preparations are required, such as checking whether the movement of each axis is smooth, whether the positioning is accurate, and whether there is shaking or abnormal noise;
• 2. Check whether the ventilation is smooth and whether there is air leakage;
• 3. Do not stand under the lifting arm to prevent safety accidents;
• 4. Non-professionals are strictly prohibited from performing maintenance work when the power is on. If there is a problem, you must first consult a professional and wait for a reply before continuing to work;
• 5. The equipment must be grounded before use.
