Laser beam welding with filler metal
Steel Research, 1999Laser beam welding generally does without the use of filler metal, in contrast to conventional welding processes. The use of filler metal in laser beam welding or in the combined GMA (gas-metal-arc)-laser beam - hybrid welding process widens the field of application for laser beam welding.

S-Polarization Laser Beam Welding
1992The availability of high power lasers with average power levels above 5 kW and high beam quality triggered a number of industrial applications of lasers. Especially the process of deep penetration welding made the use of lasers attractive in applications where low distortion and small heat affected zones are required.

Hybrid welding with arc and laser beam
Science and Technology of Welding and Joining, 1999This paper deals with a combination of two different welding processes, i.e. the synergic action of two different heat sources for fusion welding. The major part of the paper is focused on the combined action of a welding arc and a laser beam. The main advantage of the use of both heat sources is more efficient use of the energy supplied. With certain

Plasma Spectroscopy in Laser Beam Welding
1992The dependence of plasma emission spectra of the developing iron plasma on different process parameters, that is the laser power, the shielding gas flow and the feed forward, was studied during laser welding of steel using a CO2-laser and argon as process gas. The results were compared to the results of other authors (Sok 88, Roc 87).
