在1948年,瑞士首先对磁性焊剂明弧半自动焊接进行了研究,从而为焊接技术开辟了一种新的焊接方法。但当时这种焊接方法并不能满足实际生产的需要。到1952年,美国应用磁性焊剂明弧半自动焊接方法的基本特点,进一步利用CO_2气体与磁性焊剂混合使用,以便在全焊接位置(即平竖横仰)上进行半自动焊接。这一研究和试验工作,经过生产上实际使用已获得成功。利用磁性焊剂与CO_2明弧半自动全焊接位置的焊接方法,
In 1948, Switzerland first studied the semi-automatic magnetic flux arc welding, which opened up a new welding method for welding technology. But at that time this welding method does not meet the actual production needs. By 1952, the United States applied the basic features of semi-automatic magnetic arc welding flux arc welding method, the further use of CO 2 gas mixed with magnetic flux to weld in the full position (that is, vertical and horizontal Yang) for semi-automatic welding. This research and experimental work has achieved success through practical use in production. The use of magnetic flux and CO_2 bright arc semi-automatic welding location of the welding method,
