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.AC Resistance Butt Welding is the welding method that the end surfaces of two parts are pressed tightly,and the resistance heat is used to heat up the surfaces to the plasticized status,then the upsetting force quickly press them together more tight again or without applying the upsetting force pressure,just only hold on the welding pressure to complete the welding; 2.Compared to Flash Butt Welding,Resistance Welding is much easily to for worker use and operate,the cost is much lower,welding productivity is also higher; 3.The welded joint is smooth.and the welding burrs are small; 4. The structure is designed compactly which is very easily to be adjusted to weld different parts. The special butt welding control circuits ensure the welding quality; 5. Mainly used for butt welding various metal material with welding section area less than 250mm,such as iron,wires,steel sheet,pipes,etc.
Main Features: Clamp the welding parts by welding electrode firstly without touch, then driving the welding electrode slowly together with a preheat current to flash clean the oxidation and uneven surface to make welding area as hot plasticizing. The temperature of welding area turn to more and more heat and the welding current density increasing together, flash and splash make two touch surface has melted together. Finally perform a fast upsetting force on welding joint to finish welding and breaking current. This type welding joint has high strength without false welding and pores. Main Applications: 1.All kinds of dinnerware,knives ; 2.Bicycle rim,motorbike rim,car rim,or similar strip rings; 3.Various steel strip,steel rod, construction rebar,round tube and square tube ;
Supplier: Spot welders, butt welders, flash butt welders, seam welders, medium frequency inverter dc welders, single phase/three phase secondary rectifier spot welder, wire mesh welding machines, sink producing line, automatic argon arc seam welding machines, high/ultrasonic/medium frequency induction heating machines, and other automatic equipment.
1.Full digital microcomputer control system,three grades discharge design(Pre-pressing,welding and tempering),equipping functions of Constant Voltage,Constant Current,Constant Heating,Slowly Increasing,Slowly Decreasing,save multi-group Schedule Number,etc.easily meet customers high requirements of welding quality; 2.Integrated high-strength frame Structure,more impact resistant and anti-shock ability under high pressure operation,to achieve more accuracy of welding position,both spot welding and projection welding,reach the largest welding performance; 3.All copper water-cooling transformer,Multi-channel forced water cooling system to ensure the reliability of the machine running for long time; 4.Manufactured in accordance with international ISO Standard and European CE Certificate.
1. There are two types of Welding Power Source : AC Spot Welding or Medium Frequency inverter DC spot welding; 2. The lower welding electrode is designed level flat table:Welding range increased,the welded workpiece stays very flat,not deformed,no mark and smooth under welding point; 3. The up welding electrode is designed as Multi-joint arm, welding easily, without moving work piece, only move the welding gun, can weld any position in the range of the down flat table; 4. At the same time in the 200mm range the lower welding flat table can go up and down freely, by this way it is suitable for welding various shape and size of products; 5. Welding Gun can be made in two types: Vertical Welding or Horizontal Welding,choosed according to different workpiece,More easily operating and freely, safe and reliable.
1.Precision Spot Welding Machine is composed of precision spot welding power source and precision spot welding head, precision spot welding power source also can be used to work with other automation equipment; 2.With two stages current discharge control and current slow rise and slow drop function, can effectively reduce the welding spatter, improve the quality of welding; 3.Equipped microcomputer control system, can be stored 9 sets of welding specification for the user choosing; 4.According to welding requirements, optional single side double point type welding head or a single side single point type welding head; 5.Widely used in sheet metal, wire precision spot welding, such as batteries, fuses, filament, conductive terminals, instrument precision welding .
