    • A method of welding continuous or intermittent lap-penetration joints uses a gas metal buried arc (GMBA) welding process. A first component (22) is GMBA welded to an underlying second metal component (24), by forming an arc (28) between a consumable metal electrode (26) and a surface of the first component (22), depositing metal from the electrode (26) to the first component (22) and producing a pool of molten metal (10) which extends through the first component (22) and into the second component (24). The molten pool metal solidifies into a weld (30) that extends into the second component (24) wherein the weld width at the interface between the components is at least equal to the thickness of the thinner of the first component (22) and the second component (24). The arc (28) is at least partially buried within the thickness of the first component and is moved in the direction of the desired joint location to produce a joint.
    • 焊接连续或间歇的搭接接头的方法采用气体金属埋弧(GMBA)焊接工艺。 通过在可消耗金属电极(26)和第一部件(22)的表面之间形成电弧(28),第一部件(22)是GMBA焊接到下面的第二金属部件(24),从电极 (26)连接到第一部件(22)并且产生延伸穿过第一部件(22)并进入第二部件(24)的熔融金属池(10)。 熔池金属凝固成延伸到第二部件(24)中的焊缝(30),其中部件之间的界面处的焊缝宽度至少等于第一部件(22)和第二部件(22)的较薄的厚度, 组件(24)。 电弧(28)至少部分地被埋在第一部件的厚度内,并且沿所需的接合位置的方向移动以产生接头。
