The plasma cloud penetration effects are most obvious at low welding speed zone. When the welding speed increases, its impact will be reduced. The shielding gas to reach the surface through the nozzle exit pressure injection, hydrodynamic shape and diameter of the exports of the nozzle size is very important. It must be large enough to drive the spray of the protective gas covered surface, but in order to effectively protect the lens to prevent the metal vapor contamination or metal splash damage to the lens, nozzle size should be limited. The flow must also be controlled, otherwise laminar flow becomes turbulent protective gas atmosphere involved in the bath, and ultimately the formation of pores. In order to improve the protective effect, but also with additional lateral blowing. Various functions of green laser pointer with remote control will be introduced.The plasma cloud penetration effects are most obvious at low welding speed zone.

This is because the weld solidification crystallization

 As can be

seen from the figure, the organization of the butt weld all thick cylindrical ferrite. This is because the weld solidification crystallization is the process of nucleation and grew up, due to the

characteristics of laser welding heat fast cooling fast, bath center and the edge there is a big temperature gradient, leading to columnar grains in the weld development. The higher the temperature rise, the faster the temperature drops, which makes the heat affected zone, but the higher the

frequency the more small.
The hardness of the impact on the performance of tailor welded blanks (1) analysis can be seen from Figure 3.9, the overall hardness greater than the hardness of the base metal laser welding of

welded joints. This is because in the welding process, the melting of the weld metal carbonitride precipitates in the ferrite and cementite of punctate, in the subsequent cooling process, so the

weld hardness greater than any one of the base metal hardness. Large hardness variation the M170P side of the heat-affected zone hardness increased rapidly, there are much higher than the maximum

hardness of the weld and parent material near the weld position; downward trend in the DC06-side heat-affected zone from the weld to the parent material, and much lower than the M170P side of the

heat affected zone; DC06 side of the heat affected zone width is greater than the width of the the M170P side heat-affected zone. This kind of battery is one of the most commonly used Li batteries

among all batteries used by the electronic equipments including green laser pointer .
This is due to the in the M170P side of the heat-affected zone in the heating, the original solid solution precipitates in the ferrite C, N, Ti and other elements, in the subsequent cooling in the

carbonitride near the weld region gathered in the ferrite collective formation of organizations such as bainite and martensite, which makes the high hardness in the region. DC06-side heat-affected

zone, the organization of the base metal ferrite content of alloying elements, especially the lack of pinning the grain boundary carbides, austenite grain boundaries when the heating is growing up,

the heat diffusion in the crystal faster in the subsequent cooling process of the formation of ferrite microstructure thick, the width of the heat-affected zone than M170P side, so DC06 side of the

heat affected zone hardness than the hardness of the weld. That is the reason why this kind of battery of green laser pointer is called Li battery.

the need for high vacuum environment to prevent the electron scattering

After the war, has appeared in several modern welding techniques, including the most popular manual metal arc welding

such as MIG arc welding, submerged arc welding, flux cored arc welding and electroslag welding automatic or semi-automatic welding technology.

Hardening characteristics of steel depends on its chemical composition, if a steel material containing a higher proportion of carbon and other alloying elements, the higher its hardening

characteristics of indicators.  Of course, the shortcomings of the electron beam is very obvious: the need for high vacuum environment to prevent the

electron scattering, complex equipment, electron beam welding, weldment size and shape of the limitations of the vacuum chamber (non-vacuum environment is an important research direction). Due to

the existence of the vacuum chamber, the vacuum to become the main obstacle of the cycle time (currently a single electron beam equipment cycle time for gear welding is difficult to do 60s or

less); magnetic offset deflected by magnetic fields: electronic live called for the electron beam welder welding go magnetic treatment; X-ray problem: X-rays under high pressure is particularly

strong need to protect the operator. Due to significantly lower the weld strength of resistance spot welding, this process is only suitable for

the manufacture of certain products. It is widely used in automobile manufacturing, up to thousands of industrial robot welding points on an ordinary car. A special spot welding (Shot welding), can

be used for spot welding of stainless steel.The customer can select the best

green laser pointer for themselves.The customer can choose the suitable green

laser pointer according to the application.
The shallow part of the heat-affected zone, the shallowest part of the color after the end of the base metal welding, the weld near the material shows several distinct regions. Weld is known as the

melt zone, and more specifically to fill in the flux melt area, melting the material properties depends largely on the use of flux, and flux and the compatibility of the base metal.
