In environmentally friendly automobile manufacturing, laser welding sheet is very popular, such as IFS or other parts of the connection application. In fact, the mechanical and metallurgical properties of laser welded joints lead to different toughness behavior is mainly due to welding of the structure of the thermal cycling and strain cycle (thermo-mechanical effect). In the course of performance of the different fracture behavior of welded joints. Therefore, their performance after the formation of brittle. Can optimize design and improve the base metal and weld itself, the quality of parts to achieve the desired performance. However, by bending or tensile test, it is difficult to find the optimal welding conditions or ingredients. When using it, the emitter of  cell phone jammer  doesn’t need to point directly and exactly to the receiver.
In order to determine more than the performance of 10 mm thick specimen, brittle fracture experiments are widely used. In order to study welding mechanical and metallurgical behavior of the sheet / sheet due to large plastic deformation of these samples is almost impossible with a gap in the impact toughness of experiments. At the same time, changes in materials and connection technology to be able to meet the needs of the dynamic characteristics of these structures. Here some grades of steel research, such as the IF, HR60, Fe360, is especially suitable for use in the automotive industry. Laser welding, for example, in order to meet the quality requirements of the production process, has generated considerable interest in the study on the major development of the IFS puzzle welding and laser welding applications in general. The purpose of the first stage of this study is a comparative study of base metal assembly, the base material and welded joints, microstructure and mechanical toughness, taking into account the different kinds of steel grades of interstitial free steel (IF-Ti, t = 0.8 mm) and HR60 (t = 2.5mm). In all, this kind of wireless presenter cell phone jammer is good in quality, strict in parameter, perfect in performance and high in cost performance.
Following a series of experiments on the base metal and welded joints (t <4mm). Two experimental conditions, using different grades of steel (Fe360, the IFS and HR (high impedance steel)) to study the puzzle welding (welding and welding, forming). They all belong to the cold-rolled steel for the automotive industry. The percentage of carbon and manganese content from 1.4 × 10-3 to 5 x 10-3% and from 200 × 10-3 to 1440 × 10-3%, followed by columns in Table 1. Steel thickness from 0.7 to 4mm. Laser welding power from 1 to 5.5Kw three different welding speeds were 2, 2.5 and 3 m / min. The form can be evaluated in the welding zone of the laser welding process yield from 9% to 13% of the heat value of efficiency. This kind of  cell phone jammer  can be divided into red laser beam laser pointer, blue laser beam laser pointer and green laser beam laser pointer.
