In terms of welding technologies, SMAW is the most basic welding method. The learning of welding technologies begins with SMAW. With the SMAW process we normally start the arc by touching the workpiece with the tip of the electrode to cause a short circuit and then removing the electrode. The workpiece with the molten drop of core welding wire on the surface melts with electrode under high temperature forming a pool of molten metal (weld pool) that cools to form a joint. After acknowledging the main SMAW equipment and its basic operation in this course, you will acquire an intuitive and in-depth understanding of SMAW and operating techniques to gain mastery over SMAW initially.

焊条电弧焊是焊接技术最基本的焊接方法,学习焊接技术首先从焊条电弧焊开始。焊条电弧焊焊接时,将焊条与工件接触短路后立即提起焊条,引燃电弧。电弧的高温将焊条与工件局部熔化,熔化了的焊芯以熔滴的形式过渡到局部熔化的工件表面,与之熔合到一起形成熔池,熔池凝固后形成焊缝。本节课讲授了焊条电弧焊设备组成及焊条电弧焊基本操作操作技能,通过学习您将对焊条电弧焊设备及操作技术有更直观深入的了解,初步掌握焊条电弧焊的操作方法。
