Energy Coupling Rate in Aluminum Welding by CO2 Laser and Nd:YAG Laser
Nd:YAG laser CO2 laser Coupling rate
2009/6/9
The energy coupling rate during welding of Al-Mg-Si alloys with a CO2 laser and a Nd:YAG laser was measured calorimetrically. The coupling rate obtained with the Nd:YAG laser was higher than that with...
Bamboo is a regenerative resource, which can regenerate within about 3 years. In the architectural field, bamboo materials have been traditionally applied for a wide variety of purposes. However, the ...
