Problems of cell phone jammer will be solved timely

In order to solve the laser welding connector assembly of high precision and clearance requirements, welds prone to large pores, cracks and undercut defects and equipment investment, the shortcomings of low energy conversion, the development trend in recent years, laser welding is one of the laser hybrid technology . Such as laser + arc welding method, which focused on the laser welding the weld depth to width ratio, small heat affected zone, welding speed, welding energy is low, small welding deformation, the focused spot diameter is small and the energy density is high the advantages of arc welding equipment investment is small, unknown sense of the gap can be filled with the advantages of the metal. Made to increase the laser absorption rate, increase the effects of penetration and arc stability. Problems of  cell phone jammer  will be solved timely.
In addition to the laser + arc, laser hybrid technology has also developed a laser - high frequency welding, laser pressure welding and laser brazing integrated technology [3] [7], to broaden the scope of application of laser welding and the results promote the further development of laser welding technology. Three welding conditions weld penetration laser welding in the automotive industry the development of the automotive industry put forward higher requirements for quality on the body. Laser welding, cutting technology is not only in terms of processing quality superior to the traditional processing methods, and production efficiency has been significantly improved. Shown in Figure 7, in the 2l century, laser welding and cutting technology will play a crucial role in the automotive field [10]. And the record of  cell phone jammer can be the reference in the future.So that it will form a larger spot of cell phone jammer 
Figure 8 laser processing technology in the car on the application of laser welding in automobile manufacturing, the entire process including the three major types: ranging from laser welding of thick plates; body assembly and sub-assembly laser welding; auto parts Laser welding of parts. Tailored Blanks initially use the corners of Japan's Honda Motor Company in the 1960s expected to do body board and used a technology; from the mid-1980s, the tailored blanks as new technology in Europe, USA, Japan has been widespread concern [8]. The laser welded body design and manufacturing, according to the different body design and performance requirements of different thickness, different materials, different or the same performance sheet connected by means of laser cut and assembled into a whole. The action can help avoid the unnecessary trouble of cell phone jammer .
