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.

焊接专机采用了弧长跟1踪器和焊枪摆动器。由于工件表面的凹凸不平，需要焊枪随着工件表面的高低不平，需要进行上下运动，以保持焊枪与工件表面的距离一致，从而---电弧的稳定性。同时可以自动实现多层焊接。若焊接两层，当焊接完一周后，直缝自动焊接专机求购，跟1踪器检测到表面高度增加，直缝自动焊接专机厂家，则可以自动将焊枪提高。欢迎新老客户前来选购我们的产品，我公司竭诚为您服务！

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!

现代焊接技术已能焊出无内外缺陷的、机械性能等于甚---于被连接体的焊缝。被焊接体在空间的相互位置称为焊接接头，接头处的强度除受焊缝质量影响外，还与其几何形状、尺寸、受力情况和工作条件等有关。

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.

接头的基本形式有对接、搭接、丁字接(正交接)和角接等。对接接头焊缝的横截面形状，山东直缝自动焊接专机，决定于被焊接体在焊接前的厚度和两接边的坡口形式。焊接较厚的钢板时，为了焊透而在接边处开出各种形状的坡口，以便较容易地送入焊条或焊丝。坡口形式有单面施焊的坡口和两面施焊的坡口。

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.
