Nowadays, the laser welding is widely used in industries and workshops. The welding function and performance are increasingly improving and upgrading. This kind product can deal with various materials, from stainless steel to an array of alloys. Today, we will explore exactly what materials laser welding machines can weld. Firstly, let’s look at how does laser welder work.
The laser welder achieves the fusion of stainless steel by directing a powerful laser beam onto the material, inducing it to melt and form a cohesive welded joint. The resulting product typically exhibits a meticulously crafted and clean weld.
Laser welding machine has a wide range of applications and is warmly accepted by users. Next, let’s put our attention to that what materials can this machine weld.
Metals that laser welder can weld:
Common features when welding metals: As we known, laser welder machines use focused irradiation of high-energy-density laser beams to quickly melt the metal and form a uniform, fine weld. It often enables highly precise welding, producing clear, clean welded joints. At the same time, it can minimize the heat affected zone and reduce the deformation and property loss of the surrounding materials. Laser welding machines have strong adaptability to different metals and can flexibly respond to various metals by adjusting parameters.
Laser welder can provide high-precision, high-quality welding results when welding stainless steel, like 304, 316, 321, 410, 420, 430, 446.
Laser welders can also handle different thicknesses and complex geometries of carbon steel, providing more flexible application options. Carbon steels mainly involve low carbon steel(A36), medium carbon steel(A516、A572)and high carbon steel(1045,1095).
Laser welding machines can perform well when welding aluminum. Aluminum is a metal with high thermal conductivity, and the high energy density and focus control capabilities of laser welders enable it to effectively handle aluminum’s unique properties. This kind of welder is also able to cope with aluminum’s high thermal conductivity and high reflectivity, achieving effective welding by adjusting parameters and optimizing the welding process.
As copper is an excellent conductor, laser welding machines are versatile in handling various types of copper, including pure copper (C10100, C11000), copper alloys (brass: C26000, C27000; bronze: C51000, C54400; copper-nickel alloy: C70600, C71500), and electronic grade copper (C101, C102, C103).
Laser welding machines can accommodate various compositions and properties of alloy steel, achieving optimal welding results through the adjustment of welding parameters
Titanium is a lightweight, high-strength metal, and the high energy density. Using laser welder makes it ideally suited to deal with the special properties of Titanium. Given Titanium’s high melting point and reflectivity, the laser welder can effectively manage these properties by adjusting parameters and optimizing the welding process.
Non-metallic for laser welder weld
Laser welding also offers high precision and control when welding plastics. Unlike metal welding, plastic welding works by absorbing laser energy into the plastic material, causing it to melt locally and then cool to form a weld.
If you make a decision to purchase a knid of laser welder, here are some points you should tale into consideration. Let’s take a look.
Ensure that your welder is suitable for the specific type of material you intend to weld. Different materials may have varying absorption and thermal conductivity characteristics that can affect the welding process.
Laser welding is particularly effective for thin to moderate thicknesses, and adjustments may be needed for thicker materials.
Adjust the welding speed on the basis of the material type and thickness. Finding the optimal speed helps control heat input and prevents issues like overheating or inadequate fusion.
Beam Focus and Size:
Properly focus the laser beam to achieve the desired weld penetration and width. The beam size and quality play a crucial role in determining the weld joint’s characteristics.
Use appropriate shielding gases to protect the weld area from atmospheric contamination and oxidation. The choice of gas depends on the material being welded.
Positioning and Fixturing:
Securely position and fixture the parts to be welded. Proper fixturing is essential for maintaining alignment and preventing distortion during the welding process.
Control the welding atmosphere to minimize the impact of environmental factors. In some cases, it may be necessary to weld in a controlled atmosphere or under protective shielding.
Power and Pulse Control:
Adjust laser power and pulse duration based on the material properties. This helps in achieving the desired depth of penetration and controlling the heat-affected zone.
Conduct thorough inspections of the welds post-welding. This may involve non-destructive testing techniques to ensure the quality and integrity of the weld.
Ensure that operators are well-trained and experienced to operate welding machine. Proper training contributes to safe and efficient operation.
Ensure proper joint design and preparation. Clean and align the mating surfaces accurately to achieve a strong and consistent weld.
By paying attention to these factors, you can optimize the laser welding process and produce high-quality welds across a variety of materials.
