Advantages and Disadvantages of Laser Welding

Laser welding

Learn more about and its advantages in this article. You can also get some information about the training and costs of the process. This article will help you make an informed decision on whether or not is right for you. Here are some of the benefits of laser welding:


Laser welding can save time and money. The laser beam is very narrow at its focus point, resulting in a high-intensity light that heats materials evenly and reaches the workpiece with a very high intensity. Unlike conventional welding, laser welding does not require filler metal or shielding gas. Additionally, laser welding creates a low-profile weld, resulting in increased productivity. A good example of this is the fabrication of electrical boxes. MIG welding requires post-weld grinding to remove reinforced parts, but laser welding eliminates this step.


A 2.5-kilowatt laser with a chiller and cover gas costs approximately $6.42 per hour to operate at 70 percent beam on time. Other costs include consumables and external optics, which should not cost more than $0.25 per hour. Purchasing a laser unit and starting a business requires a significant capital investment, and running costs are relatively high. The following table provides a rough estimate of the costs involved.


Compared to other types of welding, laser welding is easier to control and more accurate. It also doesn’t require the use of torch or nozzle replacements, and can be integrated into automated processes, reducing downtime. Laser welding produces a high-quality weld that is virtually invisible. Its high speed and accuracy also make it a good choice for batch productions. But there are disadvantages of laser welding.


During the laser welding course, you will gain a comprehensive understanding of the technology and the processes that involve this process. This course is designed for beginning operators as well as those with some welding experience. You will learn how to handle the machine and set parameters before tackling welding procedures. This course will give you the knowledge to use the laser safely and effectively. Here are some of the highlights of the course. You can learn more about laser welding and sign up for this training course at a training center near you.


Laser welding is a process that welds dissimilar materials together using a precise beam of light. Diode lasers typically have a wavelength of 780 nm. They are highly energy efficient, and can penetrate both semicrystalline and amorphous plastics. Laser welding machines can be delivered via fiber or located locally to the weld location. The laser is deposited onto the joint with a lower fixture that provides alignments and locations.
