Resistance welding - Import export

Spot welding is different from other types of welding. There is no need to use any extra material. Two grains of metal are boiled by a classical method. Fusion is achieved by melting. The process of punting is as simple as that. Spot welding can also be called a resistance welding process. When welding, an electric current is used. Sometimes it is made using two, and sometimes more than two metals. Both pressure and heat are applied. The electrodes are copper-alloyed and are used by interacting with the metal surface. This resource is most often used in the automotive industry. It is a resistance welding process.

Welding electrodes made of tungsten, molybdenum and their alloys are particularly suitable for welding highly conductive materials such as copper. They are used in the following processes: Spot welding, Roller welding, Projection welding, Upset welding. Welding electrodes made from our refractory metals and their alloys have a relatively high level of electrical conductivity while also exhibiting outstanding stability at high temperatures. They therefore have a considerably longer service life than conventional materials such as copper and copper alloys.

Highlights: The new B 20K high-performance welding control system combines all process, measurement and monitoring systems into one comprehensive system. Stepless welding frequency adjustment between 1,000 and 20,000 Hz guarantees a highly dynamic and even finer control compared to low-frequency technologies for even better resistance welding results. From micro to macro welding processes, from resistance soldering processes to heating processes such as annealing, the B 20K covers an immense range of applications. Furthermore, up to 18 servo axes for e.g. controlling contact welding equipment can also be used to integrate press applications and other options in the B 20K.

Highlights: •Reliable welding/soldering of contact materials to manufacture contact base components •Production rates of up to 800 contact welds/min •Different device types for contact sizes up to a max. of 8.5 x 8.5 x 3.5 mm (LxWxH) •Processing of contact material for semi-finished products in profile shapes round, profile, rectangle and sheet plates •Rapid changeover system for shortest possible setup times •Servo control guarantees flexible use (also under presses)

The round tubes are manufactured from a coil that is bent and electric resistance welded (ERW). The forming process can be according to EN 10210, which foresees hot forming or cold forming followed by heat treatment, or according to EN 10219, which foresees cold forming without following heat treatments. The finished product is fully killed and welding seam bead is inside and outside trimmed. These products are used to manufacture both welded and bolted structures, in the field of constructions, engineering, industrial constructions, transports, automotive, agricultural machinery and earth moving machinery. The cold finished tubes are particularly suitable for structures at sight or for aesthetical uses, thanks to the surface aspect typical of cold forming.

Vertical sealing machines for hanging garments, suitable for packaging ironed garments such as jackets, shirts and suits. They can seal all types of bags between 400 and 700 mm in width and of any thickness. The machines carry out an impulse welding (the resistances heat up only during the welding). Welding times vary from a minimum of 0.6 sec. to a maximum of 1.2 sec. The sealing machines for hanging garments are available in the following versions: FPMM MANUAL MODEL The FPMM manual model only performs the upper sealing of the bags containing the garments. The bars are closed by manual command from the operator who acts on a lever located on the control panel. The bottom of the envelope remains open. FPMA/FPMA PLUS PNEUMATIC MODEL The FPMA model is more professional and robust and has a minicomputer that manages the functionality of the machine, from the safety devices to the working times. Thanks to it, it is possible to work in three different operating mode.

HB3 hygiene box – a worldwide novelty on the market HB3 is the first and only completely closed pallet box on the market with welded runners. The new HB3 box in industrial size (outer dimensions, l x w x h: 1200 x 1000 x 790 millimetres) consists of two one-piece injection-moulded elements: the box body as the top part and the pallet with three welded runners as the bottom part. Another special feature: A patented weld seam geometry for joining both plastic elements ensures maximum impact resistance and break strength; the weld seam is contour-milled and therefore almost invisible. The HB3 box, with a tare weight of approx. 42 kilograms (without reinforcement profiles), can carry a volume of max. 580 litres and withstand a stacking load of 5000 kilograms. The box is extremely rigid thanks to the welding of top and bottom part. Three additional metal reinforcement profiles (available as an option) permit a further increase of bending stiffness.
