Advantages Of Laser Welding

Laser welding is a state-of-the-art process for joining materials using a laser source. Lasers have evolved over time, starting with gas lasers such as CO2, which operate in a continuous mode and are typical of a higher power. 

Later came solid-state lasers such as Nd: YAG, which can operate in both pulse and continuous modes. More recently, fiber optic lasers have been developed to enable high-power welding in either pulsed or continuous modes with a greater range of flexibility.

Using a laser source for joining and depositing materials offers advantages over other welding methods due to the versatility and accuracy of the laser welding process. 

Lasers allow for better control of the heated area which results in less heat-affected zones that can result in deformations, while also providing flexibility in terms of the range of motion and beam profiles.

There are certain defects that can arise that impact the strength and uniformity of the weld. Some common defects that are seen are lack of fusion, porosity, and spatter. These defects can arise due to instabilities in the melt pool which can be a function of material properties and processing parameters. 

Lack of fusion usually occurs when there is not enough heat transferred into the joint and a uniform bond is not accomplished. This can lead to brittleness, cracking, and the presence of voids.
