little or no filler metal is added. In arc welding, only a very
light bead is required to make the joint. The open corner joint,
shown in figure 6, view C, is used on heavier sheets and plates;
the two edges are melted down and filler metal is added to fill
up the corner.
Corner joints on heavy plates are welded from
both sides as shown in figure 6, view D.
The joint is first
welded from the outside, then reinforced from the back side with
a seal bead.
