Which is better laser welding or resistance welding?
The advantages of laser welding over resistance spot welding result from the smallness of the laser spot size, the large penetration depth of the weld into the material and the requirement that only single- sided access to the workpiece is necessary.
What is the power density of laser welding?
In deep penetration welding, the laser beam is focused to a small spot and the power density can exceed 5x106Watts/m2. Sufficient energy is input to vaporise the material and a vapour-filled channel is formed through which the laser energy penetrates deep into the workpiece.
When was the first review of laser welding?
C.A. Walsh Materials Science and Metallurgy Department, University of Cambridge, England. July 2002. Note - This review is not comprehensive - the subject area is now vast. The sections on parameter modelling and temperature field calculations are the most complete parts of the review.
Why is laser welding used in sheet metal manufacturing?
Lasers are also used in the manufacture of tailored blanks, where suitably prepared sheet metal, including differing thickness and material combinations, are butt welded together prior to being pressed into the finished shape. This results in considerable cost and weight savings and increases structural rigidity.2
