    The existing problems of weld defects in welidng zinc coated steels in a overlap situation are present in the automotive industry. The root cause is the different melting temperature of zinc and steel. Zinc vapourises already at 900C versus steel melts at 1500C. The result if not taking care of the outgasing are pinholes and crates in the weld seam. Extensive researc...

    With the advancement of high power fiber delivery lasers, remote laser welding becomes a reality and more and more systems have been introduced into production lines. Remote laser welding takes the advantages of less mechanical movement and better accessibility of the beam to the workpiece, thus fast processing speed can be achieved. In most cases, remote laser weldi...
