The Main Principle of Flash Butt Welding
Butt Flash process starts the same way as the regular butt welding but since the motion of the moveable jaw is controlled and does not allow pieces to melt together, then welding current eventually overheats the contact area and the "flashing" begins emitting shower of spartks.
Advantage of this process is to allow precise control of heating up the area to be joined, with less energy used and produce repeatable dimensions of the parts.
Typical Applications
All kinds of dinnerware,cooking knives and table knives;
Bicyle rim,motorbike rim,car rim,or similar strip rings;
Various metal wire and steel strip,construction steel bar and rebar;
Round,Square and Rectangular tubes welding into "L" or "T" shape;
Mitre welding of door and window frames. z
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 ;

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.

Product description The main principle of flash butt welding: 1. The flash butt process starts when the two workpieces to be welded which are clamped by welding jams still not meet each other. 2. During the subsequence, move the welding jaws together slowly, the welding current density will increase, then the metal material in the gap between the jaws becomes molten, at the same time a�shower of sparks also being emitted. 3. As the cross-sectional area in the welding becomes extremely hot, the motion is accelerated. 4. The flashing also makes the surfaces to welded together totally. 5. Finally the upset occurs at high pressure, the welding current is cut off. Typical applications: 1. All kinds of dinnerware, cooking knives and table knives; 2. Bicycle rim, motorbike rim, car rim, or similar strip rings; 3. Various metal wire and steel strip, construction steel bar and rebar; 4. Round, square and rectangular tubes welding into "l" or "t" shape; 5. Mitre welding of door and window frames.
