Vertical Longitudinal Seam Automatic Welding Equipment
Vertical longitudinal seam welding tools are mainly used for variable polarity plasma welding. Vertical variable polarity plasma longitudinal seam welding machine adopts cross hole variable polarity plasma welding method. No groove, single side welding, double sided free forming, one penetration of medium and heavy aluminum alloy. An aluminum alloy with a thickness of 3~12mm welded.
Variable polarity plasmaarc welding (VPPAW), that is asymmetrical square wave AC arc welding, is a new type of high efficiency welding process aimed at aluminum and its alloy.
The vertical variable polarity plasma seam welding machine press workpiece length 2000mm, welding workpiece length 1800mm.
The device adopts vertical welding method, not only can increase the welding thickness, but more importantly, the weld forming stability has improved significantly. Plasma arc welding, the molten pool of liquid metal by gravity, plasma jet of positive pressure and tangential force, the liquid metal surface tension, when the plasma arc relative to the workpiece is moved upward, the comprehensive role in these forces, the liquid metal flow down along the edge of the hole, and the re formed below the perforation healing weld. The melting pool to keep dynamic welding.
The welding method
Location: when the workpiece welding workpiece will be positioned between the core shaft liner and two rows of keys by pressing keys compression plate, each row of keys can have independent electrical switch trigger plate, key compression plate pressure from compressed air.
The key board is designed with a certain swing ability, so that the key board can be attached to the surface of the workpiece strictly according to the shape of the workpiece. The distance between the keys of the two rows of keys is adjustable. The liner and back support core shaft of the longitudinal seam automatic welder can be disassembled and replaced to meet the needs of different applications of the user.
No beveling. If the straightness of the cutting plate meets the requirements, the milling and pickling process can be avoided;
Save wire and power costs;
The controllability is good. Through the selection of the gas and the change of the external conditions of the compression effect, the required atmosphere, stiffness and arc parameters can be easily obtained, which is difficult for free arc;
The weld cleaning is simple and easy to obtain the quality of primary weld;
One side welding and double face forming, the workpiece deformation is obviously small;
The stability of the arc column is straight, and the diameter of the arc column in the whole arc length varies little. When the arc column is longer, it can still keep stable combustion, and there is no disadvantage that free arc is easy to float;
From 2011,as a manufacturer main produce and sale welding products,like welding torches, nozzles, Contact Tips,in order meet more customers requirements, we started other welding sales rang, so our comapny have much experience in welding industry.
