Abstract
Abstract A welding method for forming a fillet welded joint including the steps of placing an abutting edge of a first metal member onto a surface of a second metal member at generally right angles thereto, the abutting edge having a series of alternating lands and slots extending through the entire thickness of the first member, and arc welding employing a consumable electrode to form a fully penetrated fillet weld from one side only of the joint with the weld filling the slots and melting the lands.
