P. Verrier et al., METALLURGICAL INVESTIGATION OF EMBRITTLEM ENT PHENOMENA RELATED TO WELDING ON SHEET PRODUCTION LINES, Revue de métallurgie, 92(7-8), 1995, pp. 933
Weld quality in the butt welding of coils on cold rolled sheet product
ion lines has a strong influence on line productivity and final produc
t quality. Investigations carried out jointly by the CRDM laboratory a
nd the production staff have as objective to increase the reliability
of these welding operations. A methodology is presented, which helps t
o solve possible weldability problems. It is applied to two practical
cases : the prevention of fracture after flash butt welding of IF stee
l coils, and the reduction of welding overthickness on seam welding of
packaging steel coils.
