1. Simple introduction

The welding solution is used for tube to tube/ tube to sheet automatic welding, with 3D cross laser identification and positioning technology, it is able to recognize the welding gap of tubes and guiding welding head to positioning to achieve high efficient tube to tube/ tube to sheet welding. It adopts smart design idea and no need workers involve during in working, improve the quality and welding efficient.

2. Work-piece information

● Tube material: carbon steel, stainless steel, titanium and titanium alloys

● Tube diameter: φ10-50mm (one laser scanner) or φ50-80mm (one laser scanner)

● Wall thickness: 1-6mm

● Tube stretch out: maximum 20mm

● Work-piece effective rang: φ3000mm

3. Welding technology and standard

● Full position pulse TIG self-melting/ wiring welding

● The gap from tube and tube-panel is less than 0.5mm

● Welding seam: welded surface is smooth transition, uniform appearance, good fusion, no porosity, cracks and other obvious welding defects. Weld depth and foot height meet product quality requirements

4. Main parts introduction

● Column frame

● Digital full position tube-sheet welding head

● 3D Laser identification and positioning device

● Smart multiple control system

● Digital IGBT welder

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.

Export to 30+Countries
