3. Main parts
- Mandrel: Steel structure, and the base of the longitudinal seam welding system to become one. A slot at the top of the core shaft is used to clamp the sleeve on the back of the weld seam. Can prevent the supporting core shaft temperature is too high, the water cooling equipment to ensure that the workpiece heat evenly and better shape of the back of the weld
- Fixture: The pneumatic clamp has two groups, which is used to clamp the workpiece on both sides of the longitudinal seam, which can effectively prevent the workpiece from shifting and welding wave thermal deformation.
- Control box and chain structure: The main control cabinet adopts motion controller, which can be controlled by program control. The master control box is an independent component, and all the operation adjustment and welding operation can be completed.
- Welding torch: The welding torch can be the initial position of the micro adjustment to neutralization. A system with a welding torch inclination setting function, convenient for the operator to set the position and angle of welding gun.
- Cross beam guide rail: Move the torch for traction, fitted with a linear guide rail, the linear guide rail sliding; driven by the motor, rack and pinion drive the welding torch linear movement of the carriage, the torch travel speed stepless regulation, and on the control panel display numerical.
Friendship Machinery Co., Ltd
Friendship Machinery is a world leader in automatic welding machine for steel fabrication field and industrial pipeline construction projects, providing an extensive range of equipment for a variety of project applications.
Year after year, automatic welding systems from Friendship Machinery are designed, tested, used, and continuously upgraded in every type of environment. Our customers enjoy industry-leading repair rates that are constantly improving: from less than 5% in 2001 to less than 2% in 2012.
The performance record of our specially designed and manufactured automatic welding machine is the backbone of Friendship Machinery's reputation. The proven ability of every set machine is why customers have returned to us repeatedly for new applications, designs and machinery as their products change and expand. We are proud of that fact.
Our main products: H&I beam welding line, T beam welding line, box column beam line, CNC multi-head plate cutting line, beam assembly machine, straightening equipment, steel pipe welding line, shot blasting machine, CNC flame/plasma cutting equipment, welding assisting machinery incl. Welding manipulator, welding positioner, turning roll (welding rotator), Membrane wall panel production line, which are widely used in many industries like aerospace, petrochemical, metallurgy, shipbuilding, chemical equipment, boiler pressure vessels, steel structure construction, etc.
Since 1990s, the market for steel structure building industry boomed. With fast development, very short period for construction and beautiful external appearance, as well reasonable price was occupied in the market of building industry. We invest more on developing roll forming machine such as Metal roof &wall panels machines, C&Z purlin machines drywall Stud-track forming machines , Metal decks machines , No- girder and Column curves forming machines, Guard rails forming machines , Downspout pipes forming machines and so on.
