Automatic Box Beam Production Line For Double Head Submerged Arc Welding Machine
1. Structure principle
Cantilever submerged arc welding machine and cantilever back welding machine have the same structure: moving cart, stand column, transverse boom, welding arm, seam tracking device, wire feeding system, and electric control box. Their only difference is the configuration of welding power.
Moving cart is composed of one base, four moving wheel, and 2pcs of wheel axles, 2 sets of motors. 2 sets of motors drive four wheel axles through the gear. It composes 4 wheel driving systems, in order to make it stable and reliable operation.
Box-beam cantilever welding machine has two sets of welding arms. It can weld two seams at the same time. On the one hand, it moves horizontally on beam’s guiding rail, on the other hand, it also moves vertically on tool carriage’s guiding wheels.
Seam tracking device is fixed under the welding arm. It can automatically track the welding seam to make the distance between welding torch and welding seam suitable. This device uses pneumatic tracking on horizontal direction, and automatic tracking by gravity on vertical direction.

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.
