HOGI Vertical straight seam welding machine(Square tubes and round tubes) TIG LASER WELDER
HOGI vertical straight seam welding machine is highly efficient piece of equipment specifically designed for the automated welding of vertical straight seams on workpieces. Unlike traditional horizontal welding machines, it positions the workpiece vertically or moves the welding head in a vertical direction. It is widely used for joining large cylinders, storage tanks, ductwork, and various sheet metal components.
The following is a detailed introduction to vertical straight seam welding machines:
## Working Principle and Structure
Vertical straight seam welding machines typically secure the workpiece in place, with the welding head guiding the welding torch along precision guide rails in a vertical linear motion from top to bottom or bottom to top.
• Core Structure:
• Column and Guide Rails: Provide a high-precision vertical travel path to ensure the welding process remains on track.
• Workpiece Positioning and Clamping System: Typically employs pneumatic or hydraulic piano-key clamping mechanisms to apply uniform clamping force, effectively preventing thermal deformation during welding.
• Welding Drive System: Utilizes servo motor drive with digital control of welding speed to ensure extremely uniform travel.
• Copper Backing Strip Forming Device: The rear side of the weld is typically equipped with a water-cooled copper backing strip (which may include a flux trough) to provide rear protection and assist in achieving double-sided weld formation with single-sided welding.
## Key Advantages
• Excellent weld bead formation:
In vertical welding, the self-gravity and surface tension of the molten pool, combined with specialized welding processes (such as gas-electric vertical welding), enable high-energy-input welding of thick plates with exceptional efficiency.
• Effective Deformation Control:
The piano-key style mechanical clamping system, combined with the water-cooled copper backing plate, rapidly dissipates welding heat, minimizing thermal deformation in thin-walled workpieces.
• Compact Footprint:
Since the workpiece or main equipment extends vertically, it significantly saves floor space in the factory compared to long-distance horizontal straight seam welders.
• High Degree of Automation:
Can be equipped with an automatic weld tracking system, automatic arc length control (AVC), and PLC/CNC control systems; operators need only load and unload the workpiece and start the machine with a single button.
## Common Welding Processes
Depending on the material and thickness, vertical seam welders can be equipped with various welding power sources: TIG/LASER/MIG/MAG/PAW/EGW.
## Typical Applications
1. Pressure vessel and storage tank manufacturing: Specifically, vertical seam welding for large chemical storage tanks and liquefied gas tanks.
2. Hardware and Home Appliance Industry: Longitudinal seam welding of electric water heater liners, solar water tanks, and stainless steel cylinders.
3. Duct and Pipe Manufacturing: Rolled plate welding of large-diameter ducts, environmental dust collection pipes, and water supply steel pipes.
4. Aerospace and Defense: High-precision vertical welding of various thin-walled alloy cylinders and missile casings.
HOGI Vertical Seam Welding Machine TIG System
The square-round integrated vertical seam automatic welding machine is a high-quality, efficient, and distortion-free universal automatic welding equipment for thin-walled pipes, square, and round straight seam welding. It delivers premium welds on carbon steel, low-alloy steel, stainless steel, and other materials. Optional welding power sources—including TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and CO2 welding,Laser welding—can be integrated to form a complete vertical seam automatic welding system.
Main features of the vertical straight seam welding machine:
1. It can weld both circular and square seams with a single machine.
2. The mandrel mold can automatically switch and rotate, eliminating the need to change molds for different shapes (square or round).
3. It allows for large processing diameters, no longer limited by the height of the equipment.
