The electrical control system is generally controlled by relay, PLC, single chip microcomputer, numerical control system and computer. In the welding production site, due to the welding spatter, complex water and electrical circuit, electromagnetic interference, so often used relay, PLC, CNC system. Because of the function of relay, PLC can realize programming control. With the development of technology and the emergence of new products, now PLC can also achieve complex functions, such as some CNC functions, straight seam automatic welding machine price, such as arc interpolation. So PLC control technology has been widely used in automatic welding machine.
The welding machine adopts arc length tracking device and welding torch swinging device. Due to the uneven surface of the workpiece, the welding gun needs to move up and down with the uneven surface of the workpiece, so as to keep the distance between the welding gun and the workpiece surface consistent, so as to ensure the stability of the arc. At the same time, multi-layer welding can be realized automatically. If two layers are welded, one week after the welding, the straight seam automatic welding machine can be purchased. If the surface height is increased by 1 tracker, the welding gun can be raised automatically by the manufacturer of the straight seam automatic welding machine. Welcome new and old customers to buy our products, our company will serve you wholeheartedly!
Modern welding technology has been able to weld the weld without internal and external defects, whose mechanical properties are equal to or even equal to that of the connected body. The mutual position of the welded body in space is called welded joint. The strength of the joint is not only affected by the quality of the weld, but also related to its geometry, size, stress and working conditions.
The basic forms of joints are butt joint, lap joint, T-joint (forward joint) and corner joint. The cross section shape of butt joint depends on the thickness of the welded body before welding and the groove form of the two sides. When welding thick steel plate, in order to weld through, the groove of various shapes is made at the edge, so that the welding rod or welding wire can be easily put in. There are two types of groove: one side welding groove and two sides welding groove.
