Micro Spot Resistance Welding Philippines

Fusing is used for joining insulated wires to metal terminals or crimps. Resistance heat burns off the insulation while softening the meterials to be joined, Applications include electric motors, relays with coils wound on bobbins, and lead wires that are connected to terminals or commutators.

Resistance seam welding is used to join overlapping workpieces. A pair of electrode wheels rolls over the workpieces while the power supply pulses to create a seam of overlapping weld nuggets. Seam welding is useful for continuous welding of long work pieces and for applications that require a hermetic weld.

Micro laser welding uses a laser beam energy to focus on the work to be welded. This technique features high stability in determining the position of the weld without any mechanical contact with the work. This type of welding is especially effective with spherical surfaces.

Micro arc welding controls the welding energy by transistor circuitry. A welding arc is generated in a gas between the work to be welded and a tungsten electrode. The energy of the arc welds the two metals. During welding, a jet of argon gas is applied to the work to prevent the welding area from discoloring and oxidizing. The arc is applied to the welding point without any mechanical contact, similar to the phenomenon of lightening being attracted to a lightning conductor.The electrode to - work position setting can be roughly adjusted. This method is useful for works having a stem or stud-like shape.

In pulsed heat bonding, a ceramic heater chip is heated by pulsing low voltage energy.The heat generated melts the work pieces, using the same principal as soldering, This process is best suited to resin brazing and soldering of flat cables.

Arc percussive welding generateds a plasma field between the two work pieces. Energy flows from one piece to the other in arc, which produces heat tp melt the two pieces.As the pieces reach a molten stage they are moved together forming a butt weld, Brittle metallic compounds in the work pieces are removed in the process, This welding method is useful for stranded wire and other materials with differing melting points and masses.
