一 緒論 1946～48年間,苏联烏克蘭科学院帕統电焊研究所在帕统院士親自指導之下,發明了一种新的焊接法,叫做电渣焊接法或称。在电渣焊接过程中,电流流經導电熔渣時所生的楞芝焦耳热,就是焊接热源;这裹根本没有电弧放电現象,因而所用的电源就不必具备那些在电弧焊接時为了維持电弧穩定燃燒而必須具备的种种特點。二電渣焊接过程的特點 (1)熔渣的特性根据实驗,电極末端附近必須有大量熔渣存在,是电渣焊接法的必要条件。 嚴格地說來,熔渣与熔融輔助剂(俗称焊藥)不同;後者不过是被加热到熔點的液态輔助 An introduction 1946 to 48 years, the Soviet Union Ukrainian Academy of Sciences Institute of Paving welding in Pavel academicians personally under the guidance of the invention of a new welding method, called the electroslag welding method or. Electroslag welding process, the current flow through the conductive slag generated when the Laryngotop Joule heat, is the welding heat source; This wrapped no arcing at all, so the power used to do not have to have those in the arc welding in order to maintain the arc Stable combustion must have all the features. Second, the characteristics of the electroslag welding process (1) the characteristics of slag According to the experiment, near the end of the electrode must have a lot of slag exists, is the necessary conditions for electroslag welding. Strictly speaking, slag and melting aid (commonly known as solder) is different; the latter is only heated to the melting point of liquid-assisted
