The filler wire - laser beam interaction during laser welding with low alloyed steel filler wire
AbstractLaser welding is gaining new applications in various
industries. Often the use of filler wire is not considered
due to reputation of complicity. This study has, however
gained almost no interest of research groups after millennium.
The study showed that when certain rules are followed
the filler wire feeding can be used and applied to
industrial applications. The reflection of the laser beam
from wire surface can be considerable, but I can be controlled
due to its behavior according to the normal reflection
laws. Even the fraction of beam reflecting from the
wire surface can be utilized to the process.
