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.
