Longitudinal Seam Welding MachineIntroduction1. welding object Welding objects: longitudinal seam in vitro tube. 1.1 Make sure there is no such factors influence the quality of the welding as oil stain, burr, misalignment, etc. on the welding joint area of the workpiece. 1.2 Workpiece materials: 1.3 Workpiece size range: Length: L≤1000mm Thickness of plate: 0.5-6mm Inner diameter: 80mm≤φ≤700 mm 2. welding quality requirements: 2.1 Excellent appearance, uniform texture, the width and height of the weld joint are basically the same. 2.2 Make sure there is no crack, lack of fusion, slag, pore, overlap, incomplete fusion, undercut and pits on the welding joint surface 3. welding technology and mode: Welding technology, mainly welding for the workpieces those with thin plate, adopt the non-consumable tungsten electrode,(TIG welding+wire filling) This equipment is specially designed, single face welding and double face shaping. Heat will not cause a deformation of the workpiece even so the slightest. Mating welding power is pulsed TIG power, model number:WSM-400I 4. Main Equipment Structure: 4.1 Using single column cantilever structure, mainly formed by lathebed, Pneumatic keyboard type clamp, spindle, motor planker, welding torch Pneumatic lifter mechanism, welding torch three dimensional control mechanism, air course system and electric control system, etc. 4.2 Welding-torch adopt pneumatic lifting mechanism. 4.3 The welding-torch drived by the DC servo motor linear move on the planker and rail. 4.4 Pneumatic keyboard type clamp and copper liner ensure uniform pressure and the forming of the back welding joint. 4.5 The two dimension mechanism of welding torch is for adjusting the initial position. 4.6 The distance between spindle and keyboard type clamp can be adjusted 5. Control Systems: Advanced PLC control system, humanization man-machine interface and high automation, stable and reliable performance. Automatic control the welding process. Independent speed modulating circuit, numeral display the walking speed of the welding torch and planker. It has "adjusting" and "automatic" two function state. Under "adjusting" state, it can adjust the walking speed of welding torch and dragging board, also can adjust welding torch the welding joint,the height of welding torch and the length of welding. Under "automatic" state, welding process can be done automatically. It has the function of speed digital display, digital preset welding length etc. 6. Automatic Welding Procedures: Put in the workpiece on the jig and centring ->clasp ready -> depressed the foot switch -> make keyboard clamp conpact the workpiece -> press “start” button -> welding torch drop automatically -> automatic arc strike when arriving -> achieves certain welding current the welding torch will work automatically and welding normally -> achieves setted weld length stopping welding automatically , the welding torch raise automatically -> the welding torch reset automatically at a fast speed -> loosen the clamp and unload the workpiece artificially, welding completed. 7. main technical data: LW-1000A standard set QB-0853 Control power Single-phase 50Hz AC 200V Welding power Three-phase 50Hz AC 380V Thickness of welding workpiece 0.5 6.0mm Diameter of welding workpiece 700 mm≥φ≥80mm Effective length of welding workpiece ≤1000mm (welding torch vertical) ≤700mm(welding torch tilt) Dragging planker move speed range 100 1800mm/min Welding torch pneumatic move distance 100mm Welding torch manual fine-tuning distance Y axis±30mm, Z axis±30mm Maximum allowable welding current 1000A For more details, please feel free to contact with me!
