Laser welding
Laser welding is a powerful technological process for welding carbon steel, stainless steels, as well as aluminum, copper and titanium that offer high mechanical strength. Due to the extremely fast cooling, cracking is not a major problem when welding high carbon steels compared to existing technologies. The welding quality is excellent, superior to electron beam welding. In the metalworking industry it makes the aesthetic aspect of laser welding and the absence of the use of filler metal which encourages the use of this technology.
Superior quality
The welding speed depends on the power involved, but also on the quality and thickness of the parts to be welded. The very high power available with gas lasers makes them suitable for large production volumes. Laser welding is very common in the automotive industry, precision equipment, aviation, and is gradually replacing old technologies. The welding time is very short, the heat-affected area is very small and therefore this assembly method makes it possible to damage the components.
Hybrid laser welding
There is a derivative of laser welding, "hybrid laser welding" that combines laser welding with the technique of arc welding, such as gas arc welding. This combination allows great flexibility in positioning the parts, because arc welding brings molten metal to fill the joint, and the use of laser increases the working speed compared to what is possible with the spring system. The quality of the weld is also improved.
Advantages of laser welding compared to electron beam welding - the beam
can pass through the air and does not have to be under vacuum;
-the system can be easily robotized;
-no generation of X-rays;
-better welding quality.
Laser cleaning
Laser cleaning is one of the modern methods of the cleaning process, which has quickly replaced many of the traditional methods, such as carbonic ice cleaning and abrasion cleaning, due to the many benefits it offers. Thus, fiber laser cleaning is the most efficient, safe and inexpensive solution on the market right now.
Laser cleaning technology can be achieved for a variety of reasons: to remove paint, dirt, or to prepare surfaces for treatment. Surfaces can collect or contain various contaminants, such as carbon, rust, rubber, and laser cleaning provides an efficient and environmentally friendly method for removing them without the use of chemicals, abrasive cleaning, or other destructive and environmentally hazardous methods.
