4. Preparing the edges to be welded
Welding edge preparations depend mainly on the thickness of the sheets to be joined and the welding positions. For most arc welding processes, these edge preparations are governed by the standard NF EN ISO 9692-1 . Welding sheet metal with a thickness of less than 1 mm is very delicate, if not impossible.
4.1 Butt welding
For butt-welding sheet metal of thickness (e) less than or equal to 4 mm, the preparation (figure 10 ) is of the straight-edge type, with a gap between the sheets equal to the electrode diameter. For sheet thicknesses between...
