This welding method is the use of continuous feeding of the wire

This welding method is the use of continuous feeding of the wire and the workpiece as heat between the combustion of the arc by the torch gas nozzle for arc welding. Melting polar gas shielded arc welding is usually used in protective gas are: argon, helium, CO2 gas or mixture of these gases. Argon or helium gas for the protection referred to as melting inert gas shielded arc welding (referred to as the international MIG welding); to inert gases and oxidizing gases (O2, CO2) gas mixture for the protection, or CO2 or CO2 + O2 gas mixture for the protection of gas, or CO2 or CO2 + O2 gas mixture to protect the gas, referred to as melting polar active gas shielded arc welding (referred to as the international MAG welding). Melting polar gas shielded arc welding is the main advantage of a variety of locations can be easily welded, but also with welding speed, deposition rate and so on. Melt very active gas shielded arc welding applicable to most of the major metals, including carbon steel, alloy steel. Melting inert gas welding for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys.  Current laser welding lasers used mainly for high-power CO2 laser and pulsed Nd: YAG lasers, laser development is still focused on research and development of laser devices, such as improving the stability of the power and life, to solve for high-power CO2 gas laser the stability of the laser discharge, YAG solid-state lasers to be developed for high-capacity, long life pump excitation light source. Direct diode array laser output wavelength in the near infrared region of the laser average power reached lkW, photoelectric conversion efficiency of nearly 50% of these laser equipment and technology, in welding applications play a greater role.  laser pointer can work well during the whole period of the use life of laser pointer .
Increase in beam quality of laser processing and processing peripheral device research should examine a variety of laser processing of the laser beam quality requirements, quality control of laser beam and processing technology, the first optical system design and development and processing, and materials to carry out welding, soldering process on the equipment requirements and welding process parameter monitoring and control technology, so as to equip ordinary steel, nonferrous metals and special steel welding process. The short preheating time of laser pointer can ensure the longer and more stable use of laser pointer .
The working voltage of laser pointer should be included in the instruction of laser pointer . We know that many of our daily lives in contact with the industrial products, a lot of different parts put together. The usual way riveted and welded assembly of two. Which welding is indispensable on large-scale assembly line processes.
