Latest Patents
Kashima's latest patents include a consumable-electrode AC gas shield arc welding method and apparatus. This method applies alternating current across a consumable electrode and a base metal. During the first period, the electrode is positive, and a current of a first level higher than a specified critical level is furnished. In the second period, the electrode remains positive while the current is reduced to a second level lower than the first level. The third period involves the electrode being kept negative at a third current level. These periods are periodically repeated to enhance the welding process. If the arc voltage drops below a predetermined voltage during the first period, a current of a fourth level higher than the first level is furnished until the arc voltage exceeds the predetermined level.
