Description
Technical field
the utility model relates to a kind of welder, relates in particular to a kind of brazing device for Automobile Welding.
Background technology
soldering and fusion welding method difference are: when soldering, mother metal does not melt, and the fusion temperature of solder is lower than mother metal, and heating-up temperature, connects mother metal after solder melted by heat higher than solder liquidus curve lower than mother metal solidus.The major requirement of soldering processes that automotive field uses is: efficiency is high, weld strength is high, smooth welding joint, do not destroy zinc coat.
the most extensive and common in automobile manufacturing field use at present, mainly contain two kinds of soldering processes devices, i.e. laser braze welding and CMT(cold soldering) soldering tech.
the first brazing device is that laser braze welding is also referred to as laser wire filling brazing, the process unit of this laser braze welding technology is mainly made up of laser generator, optical fiber, plumb joint, wire feeder and robot, using laser as thermal source, the laser being sent by laser generator, have certain power is by wire melting, welding wire and laser beam and weld seam are at an angle, then utilize the traction of robot by the welded part of wetting of fusing, the welding wire of final fusing is filled between the workpiece of required welding, thereby completes welding processing.(utility model people: uncommon in W crow, Welding Technology Co., Ltd of Switzerland, the patent No.: 200580024040, international publication number WO2005/118196, international publication day: on December 15th, 2005, for the method and apparatus of solder brazing)
the advantage of laser braze welding is that efficiency is high, weld seam is narrow, nothing is splashed, face of weld is smooth, reply gradient is high, protects zinc coat etc., because face of weld quality is good, after general laser braze welding, can directly paint.
the second soldering processes device is CMT cold soldering technology.CMT is the abbreviation of COLD METAL TRANSFER, and so-called cold soldering technology is by Fu Niusi (FRONIUS) company's utility model and take the lead in applying in Automobile Welding field.CMT soldering tech is take gas metal-arc welding as basic principle, helps welding wire with molten drop to separate by the pumpback campaign of welding wire at welding wire during with the short circuit of welded metal surface, therefore have sweating heat input low, without the significant advantage such as splashing.CMT brazing device forms (utility model people: Joseph's Lay cloth by CMT power supply, CMT wire feeder, robot, CMT welding gun (band push-and-pull silk device), CMT controller etc., this Mel of Joseph's Aunar that, patent publication No.: CN101421068 A, open day on April 29th, 2009, a kind of workpiece welding method Method of welding a workpiece).
also have a kind of soldering tech relevant to the utility model-automatically TIG soldering, the automatic wire filling brazing device that to use argon tungsten-arc welding power supply be thermal source, welding wire has used cored solder wire.Automatically TIG brazing device comprises robot and automatic wire feeding mechanism.Plasma arc is by wire melting and be filled into and in weld seam, realize brazing.Automatically the advantage of TIG brazing device is that welding deformation is little, weldquality is best (pore-free), weld seam is attractive in appearance etc.
