With the use of laser soldering has the following advantages compared to other 1, as is the local heating element easy to produce heat injury, heat affected zone is small, it can be implemented in the vicinity of the thermal component soldering. 2, with non-contact heating, melting bandwidth, without any tools, can be double-sided printed circuit board components and equipment after the processing. 3, repeat the operation stability. Flux on the Welding Electrodes pollution, and the output power of laser irradiation time and is easy to control, laser soldering yield. 4, UV laser beam is easy to implement, use semi-lenses, mirrors, prisms, mirrors and other optical components scan time and space partitioning, to achieve more symmetrical while welding.Welding Electrodes 5, multi-wavelength laser soldering 1.06um laser as the heat source, use fiber optics transmission, it can be difficult in the conventional way of welding parts for processing, good flexibility. 6, the focus is good, easy to implement the automation of multi-site installations.
Arc welding coated electrodes is short for manual metal arc welding. Is manipulated by hand on the arc Welding Electrode for welding method.
It uses the electrode and the workpiece burning electric arc between the electrode tip and the melt of the workpiece part, the rapid melting of the electrode tip to a small droplet of metal by the arc transition to the partial melting of the gold artifacts have been in session, and with the integration of together form a pool, with the arc to move forward, gradually cooling bath of liquid crystals to form metal weld. Welding process. Arc welding electrode core is a pole, and as a weld filler metal melting after the woven part; drug percutaneous electrode arc melting of high-temperature decomposition and generate gas and slag, the payment term from the droplet and weld pool protection against air pollution and the role of metallurgical reactions; some drugs by adding metal powder to the skin to provide additional weld filler metal.
