摘要：

In gas tungsten-arc welding (GTAW) with longitudinal magnetic field controlling, the distribution of arc plasmas force and electrical current density are measured by a barometer method and a probe method. The rules of distribution are analyzed. Under the conditions of weak magnetic field and small welding current, the distribution models of arc plasma force and electrical current density in GTA welding with longitudinal magnetic controlling are established.
