1. Introduction
Longitudinal Seam Welding Machine is mainly used for welding longitudinal seam of thin sheet. It adopts cantilever type, and it is mainly composed of frame, fingers-type clamping unit, water cooling mandrel, traveling carriage, crossing slider, wire feeder and torch holder.
Artificial workpiece pushed in juxtaposition to the core shaft artificial weld position, pneumatic keys clamp work piece side pressing, electric torch shift to the weld joint, electric drop of welding gun, fine tune the torch alignment, welding press welding "button, the welding power supply automatic arc, arc stability, welding torch automatic walking, began to normal welding process, to set the welding length automatically stop welding, automatic welding gun rising, torch automatic reset high-speed, gas moving platen release, hydraulic pressure to open the mandrel hanger, unloading the workpiece, automatic welding.

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.
