There are a lot of imitation laser welder on the market, also called laser cold welder this welding cylinder is not possible, the cylinder welding pressure requirements are very high strength requirements are also high, imitation laser welding lies more in some of the not critical force or bearing parts of the welding, or not the pressure requirements of the parts, compared to fusion welding such as welding or TIG welding, this welding welding welding cylinder is indeed an undesirable welding! The welding method is really an undesirable welding method.
