		Laser  Welding Machine 
		
		
		  
		
		
		The optical fiber delivery laser welder is a kind of 
		laser welding equipment that couples the high energy laser beam into the 
		optical fiber, collimates to parallel light by collimating lens after 
		long distance transmission, and then focuses on the work piece to weld. 
		For the positions hard to reach, implement flexible noncontact welding 
		to have more flexibility. The laser beam can realize spectroscopy in 
		time and energy and process multiple light beams simultaneously, making 
		more precise welding possible.

		1. 
		
		CCD monitor system is equipped for observing and 
		precision positioning. 
		
		
		2. 
		
		The welding spot energy distributes evenly and has the 
		perfect light spots required by welding characteristics. 
		
		
		3. 
		
		Suitable for complex welds, spot welding of different 
		devices and seam welding of thin plates within 1mm;

		Ceramic converging cavity is imported from the Britain. 
		It is corrosion resistant and high temperature resistant, and has 8-10 
		years service life. The life of xenon lamp is more than 8 million times.

		Laser welding is the most flexible and modern method to 
		join together different materials. With STCP welding machine, it is 
		possible to weld together metals, such as steel, stainless steel, 
		platinum, gold, titanium, brass, bronze, nitinol, and other alloys, as 
		well as semiconductors and other diverse materials, without the use of 
		solder or soldering flux. 
		
		
		  
		
		
		The latest laser technology along with modern control 
		techniques and ease of maintenance are all combined in this pulsed 
		laser-welding system. This system is developed mainly for 
		micro-processing and, highly suitable for applications in research and 
		development as well as in small-scale manufacturing. 
		
		
		  
		
		
		The welding system is available as a beam source (laser 
		class IV) or with a sealed processing chamber (laser class I). The 
		software of the laser welding system runs under the operating systems 
		Windows 95/98, Windows NT, and Windows 2000/XP.  
		
		
		  
		
		
		The beam source is a pulse-driven Nd:YAG laser that emits 
		light with a wavelength of 1064nm. The laser energy is transmitter 
		through a quanrtz-glass fiber and is focused on approximately 100um.

		Option 1: Stereo Microscope  
		
		
		In order to attain a very small focus, the beam of the 
		laser is coupled with a microscope. In this case, the high quality lens 
		of a Leica microscope is used to focus the laser beam. Thus, a 
		perpendicular observation of the workpiece is possible. 
		
		
		  
		  
		
		
		Option 2: Sealed Processing Chamber (Laser class I) 
		
		The sealed 
		processing chamber of laser class I allows for the manual positioning of 
		the workpiece. Inside the chamber there is a table with an adjustable 
		height that can be positioned in the focus of the microscope through the 
		use of two handles. The table has a thread-raster in order to fix the 
		sample holder or XY translation stage. The observation can take place 
		through the large protective window, the oculars of the microscope (with 
		integrated protective filters), or a monitor connected to an optional 
		CCD camera.
