The picture of green laser pointer will be included.
The green laser beam light of green laser pointer is not that stable
The following will be the thickness of classified materials, microstructure and properties of two different combinations of thick and ranging from thick description. 0.1mm/0.1mm of 316L grade

austenitic stainless steel sheet for 00Cr17Ni14Mo2 laser welding test by changing the welding parameters to obtain the excellent performance of welded joints. The test results show that, in the

selection of a small current, pulse width, high-speed, high frequency conditions of the weld from the central part of small equiaxed grains and the edge of small columnar crystals. Equiaxed grains

and columnar grains at the junction of the local emergence of a clear dividing line, as shown in Figure 1.5. Also found that the weld heat affected zone is very narrow, almost invisible. The

operation mode of laser pointer is very simple.
Figure 1.3 - Figure 1.4. Axis crystal hardness of the weld edge corresponding to the hardness of the fine columnar grain and center of the weld is small, the high hardness of the weld hardness than

the total on page 11 of Anhui University graduation project (thesis) report paper base metal, as shown in 1.6 shows. Because the hardness and grain size, content of alloying elements. Weld grain

than the parent material grain small, and therefore higher hardness; columnar grain alloy element content ratio of alloying elements in the axis crystal content is slightly higher, so the hardness

also slightly higher. Parent material tensile strength of 778 MPa, tensile strength of weld 739MPa, can reach 95% of the parent material, 14% of the elongation rate of the base metal, weld

elongation rate of 12% can be achieved by the mother 85% of the material. green laser pointer is very convenient for the customer to operate.
Joints decrease the mechanical properties the reason may be the dividing line at the junction of the weld middle-axis crystal and columnar grain. Fine columnar grain structure of equiaxed grains

Figure 1.4 weld edge, Figure 1.3 the center of the weld small, etc. Figure 1.5 weld center axis of crystal and the edge of the dividing line of the columnar crystals in Figure 1.6 316L

microhardness of the laser welding head distribution (2) Wudong Jiang et al. [16] of 2 mm / 2 mm thickness, containing 35.4% nickel Invar welding experiments, test single factor method, the choice

of process parameters such as shown in Table 1-1, each experiment to change the laser equipment a parameter.
