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.
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.
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.
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.
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.
