Abstract
A method of welding a first metal plate to a second metal plate including the steps of affixing a back-up bar by use of spaced welding tacks to the flat surface of a first metal plate, forming an abutting edge on the second metal plate a series of alternating lands and slots, the slots extending through the entire thickness of the second metal plate and the length of the slots being substantially greater than the length of the lands, positioning the formed edge of the second metal plate so that the lands thereof engage the flat surface of the first metal plate and a substantially continuous slot is formed between the plates and in which the second metal plate is in engagement with the back-up bar to form a joint, arc welding with a consumable electrode in the substantially continuous slot to form a weld, the weld penetrating portions of the flat surface of the first metal plate, the entire abutting edge of the second metal plate and a portion of the back-up bar and melting the lands and the welding tacks and in which the welding step is preferably performed in one pass.
