Automatic argon arc welding longitudinal seam welder is a universal automatic welding equipment to realize butt longitudinal seam welding of thin-walled cylinder, conical cylinder, square tube, flat plate or rectangular body. It can be used for high-quality welding of carbon steel, low-alloy steel, stainless steel, aluminum and their alloys, and can be composed of argon arc welding (with or without filler wire), submerged arc welding (CO2/MIG/MAG), plasma welding and submerged arc welding. The thickness of the welded workpiece is 0.2-7 mm.

First, the main engine adopts cantilever structure, which is convenient for workpiece loading and unloading.

Secondly, the welding trolley adopts precision guide rail to make the trolley walk smoothly; DC motor drive, stepless adjustment of welding speed; The welding gun clamping mechanism is two-dimensional adjustable pneumatic lifting.

Thirdly, the pneumatic keyboard fixture is used to distribute the pressure through the flexible air bag, so that the weld is evenly pressed in the whole welding length range; The welding mandrel is provided with a back protection welding pad to ensure that the back of the weld is formed, so that the workpiece is welded on one side and formed on both sides; Gas protection is carried out on the back of the weld by opening the gas hole; The distance between the mandrel and the keyboard clip can be adjusted as required; And there is a welding seam centering device. For workpieces with smaller diameters, we specially designed and added a set of aligning system to further improve the working efficiency of customers!

Fourth, the main controller of the system adopts PLC as the core control unit, and can adopt various control output signal selection and output interfaces according to the requirements of welding process, which has the characteristics of strong anti-interference, high reliability, stable speed regulation, convenient operation and high degree of automation.
