The mechanisms leading to process pores in deep penetration laser beam welding are discussed in this paper. Process pores were observed since the beginning of laser welding. Although there are differences in the number, size and location of the pores depending on the used laser type and beam parameters, process pores are a common problem for all laser sources. To clarify the mechanisms, basic experiments...
A generalised view on the causes leading to humping during high-speed seam welding is proposed. It is based on the fact that, whenever the melt velocity in a welding bead exceeds considerably the welding speed, the weld groove cannot be completely filled by melt at any location and any instant. As a consequence of solidification from the walls of the weld groove, the shape of the free cross section...
