美国洛斯—阿拉莫斯国立实验室一位研究人员研制成一种便携式焊接装置。这种装置能保证焊接接头的连续并避免氧化。据称,这种装置在焊接时仅仅使焊接接头处于控制气体下,就能使金属管或类似工件焊接得很好。过去用过气体保护,但是这些技术不易掌握且成本高昂。这种装置则可使用各种气体,如氮、氦、氩或二氧化碳。装置的配气头作为充气旋 A researcher at Los Alamos National Laboratory in the United States has developed a portable welding device. This device can ensure the continuity of the welded joints and avoid oxidation. Allegedly, this device in the welding welding only in the control of the gas under, you can make a metal tube or similar welding well. Gas protection was used in the past, but these technologies are not easy to grasp and costly. This device can then use a variety of gases, such as nitrogen, helium, argon or carbon dioxide.
