Pneumatic Spot Welding Machine

Introduction Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). That permits the welding to occur without excessive heating of the remainder of the sheet. Applications: 1. Mild steel sheet, stainless steel sheet, galvanized metal sheet spot welding. 2. Metal sheet fixing welding before continues rolling seam welding. 3. Welding fan guard (with proper designed fixing and driving system), welding metal art ware, stationery, cook ware. 4. With special made electrode, it can weld small mesh, birds cage, pets cage, condenser and similar work piece. 5. Weld connection parts, the hinge, nuts and bolt welding, low carbon fasteners and stainless fasteners. 6. Welding high conductive material, like aluminum, electrical contact, copper wire etc.(using Middle frequency power) Single plate thickness: 1. Uncoated mild steel sheet: 0.4-4.0mm 2.

New universal butt-flash welding machine has been successfully developed efforts of welding Technologies USA and Guangzhou DuroWelder Ltd. This unique machine combines latest developments in welding science and the best quality components found around the world.Electromechanical drive made in USA allows super precision control of speed and upset force, exceeding even hydraulic type drives for its material range. Welding control made by European manufacturer allows versatile weld parameters to be implemented, including annealing process when required. Precision rails guarantee perfect alignment in between welded pieces therefore minimizing possible waste when weldments are machined. Guang Zhou DuroWelder technicians, trained by the experts from parent Company Welding Technologies, demonstrate world-class craftsmanship in manufacturing process and assembly of the machine. Butt-Flash welder can be adjusted from one type of product (e.g.30mm dia steel rods) to another (16mm dia copper squares) within minutes. Water cooled transformer available as 100KVA option along with water cooled SCR and Jaws provide comfortable conditions for heavy duty application when high rate of production is required. This universal butt-flash welder can be ideal in situations when manufacturer has to produce small batches of weldments made of various sizes and material. 100KVA option welds 30mm dia mild steel, or 20mm dia copper rod. 200KVA option increases range of welded parts by 40%. Water cooling flow: 12L/Min. Air Pressure: 0.6Mpa. Clamping Force: 6,000kgf. Upset force: 3,000kgf. 1000kg.

1.Electrode Force is easily adjustable. 2.Powerful DC power supply produces welds in short time, practically no sparks and no discoloration. 3.Heat impact from welding is so small that it does not change any characteristics of the battery being welded. 4.Weld spot has the same color as the welded material. 5.All welding parameters are controlled from a keypad on the front of the machine. 6.Controller LCD panel displays welding parameters making process control accurate and convenient.
