One of the best features of https://www.hmlasercutter.com/ is its speed. It makes welds very quickly, and with a concentrated heat input, it can increase travel speeds and increase the thickness of materials. Read on to learn how https://www.hmlasercutter.com/ works and why it’s a great option. Here are some benefits of laser welding:
High weld quality
This research aims to develop laser welding processes that can provide high weld quality, even when beam speeds are relatively slow. Laser welding processes can be used to produce high-quality joints when beam diameters are 630 mm and larger. The beams used in these experiments have a spectral resolution of 50 um, and the beam quality factor is M2 30. High-speed laser welding is highly effective for high-quality welds, but it requires a lot of patience and training to get a good weld.
Faster than MIG welding
There are a few differences between MIG welding and laser welding. MIG welding typically proceeds at about 20 to 30 inches per minute, while laser welding can weld as fast as 200 inches per minute. Aside from speed, laser welding is also better for post-processing because it doesn’t require a grinding cycle. However, laser welding does require higher price than MIG welding, as it requires a robotic arm with great path accuracy and repeatability.
Less thermal distortions
Laser welding has the advantage of causing less thermal distortions, especially in critical areas, as compared to other methods. This is because laser welding uses a much larger area than traditional methods, and thus the heat sink effect is less noticeable. In addition, the process is faster, which makes the distortions less visible. But why does laser welding produce less distortions? Let’s find out. Let’s begin by examining some of the most common thermal distortions caused by welding.
Improved tolerance to joint fit-up
The smallest spot size can significantly improve the joint fit-up tolerance. At 400 um, the misalignment with the joint should be less than 0.3 mm. At 600 um, a maximum misalignment of 0.5 mm is acceptable. In other words, a 0.5-mm gap is acceptable when the joint thickness is 10% of the lowest sheet thickness. Welding with wire feed improves the fit-up tolerance. For more information on how to perform laser welding, visit the website of Joining Technologies.
Lower mechanical property reductions
In the present study, we demonstrate that lower mechanical properties are achieved in laser-welded joints, compared with the standard welding processes. The experimental procedure was performed on a fabricated specimen. The laser beam was oriented at an angle of 5 degrees toward the vertical, which avoids any possible damage to equipment caused by the reflection of the beam. In addition, we used a shielding gas, argon, flowing out of a paraxial copper gas nozzle of 8 mm in diameter. The applied welding parameters are shown in Table 2.
