Current automobile industry the fuel car from the tradition to energy-saving transform with car of new energy resources, and laser solders to join advancedly as a kind method, each old car manufacturer is opposite the world to its are having strong interest and increase corresponding basic research and the applied promotion that study positive result accordingly. Laser solders, it is a kind of when stimulate beam of light to serve as heat source when use high energy density efficient nicety solders method, it is one of main fields that laser material processing technique uses. Current, rise as what the adjustment of structure of the sources of energy and environmental protection ask, auto industry is being sided with light quantify direction to develop, new-style light the use that quantifies material is implementation the car is small one of quantified significant steps. And laser solders to join in implementation with its distinct advantage light the effect with quantify data side to rising mainer and mainer. The car is small quantifying is not understand according to literal meaning " reduce car weight " , be in however assure car quality to go up, use more new data at car function, in structural member, the performance that lets car component is more superior, weight is lighter at the same time, assure what pair of the sources of energy decrease in car travel process to use up, achieve multiple result. Current, the car is small quantify a technology to basically come true through the following kinds of ways: The proportion of light simple stuff is climbed ceaselessly litre, composite material of alloy of aluminium alloy, magnesium alloy, titanium, high strenth steel, plastic, pulverous metallurgy, zoology and pottery and porcelain applied; structure is optimized and of component modular design level rises ceaselessly, if use front-wheel drive, high rigid structure to mix,exceed light suspension structure to wait will achieve light quantified purpose, the computer assists compositive technology (the development; that incorporates the technology such as CAD/CAE/CAO) and structural analysis makes automobile manufacturing industry innovate ceaselessly on figuration method and connection technology. Laser beam welding is received is to aid shift a car light quantified crucial technology realizes a car 3 kinds in above light in quantifying a way, laser Cutting and laser beam welding are received with distinct advantage, became implementation the car is small quantified main technique measure. Say with respect to fetch of laser beam welding, laser beam welding is received do not have osculatory sex, in machining a process, need not product of lay a finger on can realize nicety to solder, and traditional join pattern, have a plenty of rely on screw to tighten solid, have a plenty of adhesion relying on glue to receive, the to accurate sex and consistence requirement in can not satisfying contemporary car to make, and traditional pattern also does not apply to join new material. Under photograph comparing, laser beam welding is received in connective consistence, without seam gender, nicety technology implemented on gender and clean sex span type progresses, the shaping with will become future important means. Technology of laser beam machining is implementation the car is small one of quantified important ways, prospective laser technology applies foreground in car domain capacious. Those who want to implement pair of laser technologies is luckier with, must want to have process of laser and material interaction mechanism, laser beam machining systematically nondestructive detects and the fundamental theory such as control studies; research laser is deep fusion welding accepts theory, development laser is three-dimensional solder technology and equipment; research are different board data of thick, different automobile, especially light the laser beam machining that quantifies material spells solder technology and equipment.
