Multipass welding with laser and GMAW

March 2009
Industrial Laser Solutions;Mar2009, Vol. 24 Issue 3, p2
The article discusses the initiation of a HyBright project funded by the Federal Ministry of Education and Research in Germany which intends to lessen the number of weld passes and processing time. Joining thick steel plates using conventional gas metal arc welding (GMAW) processes needs a high number of different weld pass. Hybrid welding which is a combination of a laser with GMAW is said to be a promising approach that could lessen the number of weld passes and welding time.
