Ensure safety and security of the personnel who deals with  cell phone jammer
Multifocal technology, the basic principle is: the combination of different lenses and mirrors, so that the laser emits a beam decomposition for multi-channel (or directly using the simple method of multiple transmitters), so that the weld surface will form the focus of the most commonly used is a dual-beam laser (focus). The dual-beam laser two focus parallel distributed around the weld on both sides, or before and after the distribution in the weld center line. Parallel dual-focus wide weld laser welding, while the use of the tandem type, the temperature gradient of the heat affected zone will be greatly reduced to avoid the biting edge of weld defects. Laser to fill silk laser welding with filler wire welding and general filler wire welding process is similar.  It can be seen, with the decrease of welding speed increase weld molten pool width, which is makes the welding heat input per unit area decreases, and decreases the melting of the base metal, welding speed increases, so the weld width is reduced. 3.3.4 the heat affected zone (1) DC06 side of the heat affected zone of Figure 3.21 is the organization of the DC06-side heat-affected zone in welding speed change. Here will introduce a tiny type of green cell phone jammer in more details.  Weld cross-section changes with the energy of the welding line between the welding process. (B) the geometric characteristics of laser welded joints. (C) the impact of welding power and welding speed and penetration of the welded joints. (D) three different kinds of steel to the weld heat affected zone to the weld metal microhardness changes from the parent material. The report of the 47 total pages of Anhui University Graduation Project (Thesis) Paper Figure 3 is about typical dendrites, shows the size of the primary dendrites and secondary dendrites depends on the cooling rate of the different kinds of steel. Compared with the infrared technology of wireless presenter  cell phone jammer , the radio frequency of wireless presenter laser pointer can transmit the signal in the whole 360 degree direction.
Therefore, Figure 3 (b) shows the relationship between the three different steels: IF-Ti, IF-of TiB and Fe360 in the welding process in the cooling rate and dendrite size. In order to highlight the point of view of this study point out here that these are valuable. Figure 3 - (a) steel typical dendrites, Ⅰ and Ⅱ, respectively Fe30 and IF-Ti on the size of the primary dendrites and secondary dendrites. (B) the relationship between the three different kinds of steel cooling rate in the welding process with the main dendrite size. However, many studies have shown that there are many types of NA experiments, such as: fracture from the weld zone in the base metal, weld very narrow, and so on. In addition, the cooling time increases, the increase in heat input reduces fracture toughness. This characteristic of this kind of  cell phone jammer  utilizing the radio frequency will be more convenient for the customer’s use.
