Horizontal double circumferential seam welding machine is used for butt welding of circumferential seam between cylinder block and cover plate. The system mainly includes mechanical part, arc length yaw control system of welding power supply and welding auxiliary equipment. The main functions include welding start, stop, welding time control, welding current control, rotation position control, welding speed control, reserved automatic wire feeding function, etc.

可编程控制器配置为实现控制系统的逻辑控制，具有小型化、高速、高性能、大容量等特点。控制系统的其他电气元件，如继电器、接触器、存储单元、信号采用和传输元件，各种行程开关均采用元件，使控制系统的可靠性大大提高。控制系统与焊接电源集成，可实现设备动作与焊接过程的无缝衔接，达到理想的焊接质量。

The programmable controller is configured to realize the logic control of the control system and has the characteristics of miniaturization, high speed, high performance and large capacity. Other electrical components of the control system, such as relays, contactors, storage units, signal adoption and transmission components, and various travel switches adopt high-quality components, which greatly improves the reliability of the control system. The control system is integrated with the welding power supply, which can realize the seamless connection between the equipment action and the welding process, and achieve the ideal welding quality.

采用卧式焊台结构和导轨床身，可靠保证气动尾座与机头距离可调。机头转动，主轴由变频电机驱动，焊枪支架由减速电机无级调速驱动。该产品由转台、气动夹紧、焊枪气动升降机构等组成，装卸方便，机动性好。电控系统采用程序控制，焊接参数预置，操作简单，设置方便，自动化程度高。也可以根据需要使用PLC编程控制器的控制单元，通过修改控制软件程序和焊接参数来调整设备的功能。

The horizontal welding table structure and guide rail bed are adopted to reliably ensure that the distance between the Pneumatic Tailstock and the machine head is adjustable. The machine head rotates, the main shaft is driven by the frequency conversion motor, and the welding gun bracket is driven by the stepless speed regulation of the reduction motor. The product is composed of rotary table, pneumatic clamping, welding gun pneumatic lifting mechanism, etc., with convenient loading and unloading and good mobility. The electric control system adopts program control, welding parameter presetting, simple operation, convenient setting and high degree of automation. The control unit of PLC programmable controller can also be used as required to adjust the functions of the equipment by modifying the control software program and welding parameters.

山东自动焊接设备厂家认为，钨极气体保护焊是一种非熔化气体保护焊，利用钨极与工件之间的电弧使金属熔化形成焊缝。在焊接过程中，钨电极不会熔化，仅起到真正电极的作用。

Shandong automatic welding equipment manufacturers believe that tungsten gas shielded welding is a kind of non melting gas shielded welding, which uses the arc between tungsten electrode and workpiece to melt the metal to form a weld. In the welding process, the tungsten electrode will not melt, but only acts as a real electrode.

同时，从焊枪中送出氩气作为保护气体。钨电极可以控制热量输入。是钣金连续焊接和底焊的一种方法。焊接电流是脉冲的形式，所以学会了焊接管道。这种方法几乎可以用于所有金属的焊接，尤其适用于铝金属的焊接。采用这种焊接方法，焊缝质量高，焊接速度快。

At the same time, argon is sent out from the welding gun as the shielding gas. Tungsten electrode can control heat input. It is a method of continuous welding and bottom welding of sheet metal. Welding current is in the form of pulse, so I learned to weld pipes. This method can be used to weld almost all metals, especially aluminum. With this welding method, the weld quality is high and the welding speed is fast.
