Summary
This paper summarises fatigue strength in laser‐welded butt joints made of Fe P04‐UNI 8092 deep drawing steel with standard and galvanized surfaces. The Wöhler curves obtained are compared with those of a series of seam‐welded joints, which have been subjected to special forging of the beads after welding.
Fatigue behaviour is similar to that of the parent material since fracture does not occur in the beads or heat affected zone. Such results are of importance in the current review of design methodologies, when new possibilities are being offered by laser and tailored blank technologies.
