06 μ M, the beam of light that main good point is generation can be passed fiber-optic and deferent, the beam of light with because this is OK complex leave out is deferent system, apply to flexible production system or long-range treatment, use at soldering normally the work with precision higher demand. Power of commonly used output is auto industry the Nd:Y of 3-4 kilowattAG laser. Another kind is aeriform laser, call CO2 laser again, molecular gas makes working medium, generation is on average 10.
The infra-red laser of 6 μ M, can work continuously and output very high power, standard laser power is between 2-5 kilowatt. The characteristic that laser beam welding receives is workpiece be solderinged is out of shape dinky, have join space hardly, solder deepness / width comparing is tall, because this solders,quality solders than the tradition the method is tall. But, be like to the quality that makes sure laser beam welding is received, namely laser beam welding receives a process to monitor be being controlled with quality is the serious content that a laser uses a field, include to use all sorts of sensor such as inductance, capacitance, sound wave, photoelectricity, pass computer processing, in the light of different solder object and requirement, welding line of implementation such as dogs, blemish detects, welding line quality is monitored wait for a project, through feedback control adjustment solders craft parameter, realize automation laser beam welding to receive thereby. Solder in laser in, position of focus of beam of light is one of the most crucial control technology parameter, mix in fixed laser power solder below speed, only the focus is in the ability inside optimal position limits to win the welding line figure of deep become reconciled of the biggest frit. Solder in actual laser in, affect the factor of focal position stability to avoid and decrease, need special clamp and equipment technology, the exact extent of this kind of equipment and the quality discretion that laser solders supplement each other. In auto industry, laser technology basically is used at automobile body to spell solder, solder with the spare parts. Laser spells solder is in automobile body the design is made in, according to automobile body different design and function ask, choose the stencil steel of different specifications, install what the technology finishs place of automobile body some to make through laser cut is cut and going all out, for example before inside frame of archives wind glass, door board, automobile body motherboard, central post. Laser spells solder to have reduce spare parts and mould amount, reduce spot welding number, optimize material dosage, reduce spare parts weight, reduce cost and raise dimension precision to wait for advantage, had been mixed by a lot of old car manufacturer at present fittings supplier is used. Laser beam welding receives what basically be used at structure of automobile body frame to solder, for example of coping and flank automobile body solder, the tradition solders resistor spot welding of the method has been soldered by laser gradually be replaced. Receive a technology with laser beam welding, workpiece joins the joint range breadth between can decrease, reduced plank to make dosage also raised the stiffness of bodywork already. Laser beam welding receives component, the spare parts solders place was not out of shape almost, solder rate is rapid, and the heat treatment after needing solder, at present laser beam welding receives component to be used already extensively, common wait at hinge of tappet of transmission gear, valve, door.
