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.

山東自動(dòng)焊接設(shè)備廠家認(rèn)為，鎢極氣體保護(hù)焊是一種非熔化氣體保護(hù)焊，利用鎢極與工件之間的電弧使金屬熔化形成焊縫。在焊接過程中，鎢電極不會(huì)熔化，僅起到真正電極的作用。

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.

同時(shí)，從焊槍中送出氬氣作為保護(hù)氣體。鎢電極可以控制熱量輸入。是鈑金連續(xù)焊接和底焊的一種方法。焊接電流是脈沖的形式，所以學(xué)會(huì)了焊接管道。這種方法幾乎可以用于所有金屬的焊接，尤其適用于鋁金屬的焊接。采用這種焊接方法，焊縫質(zhì)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.
