Comparative Advantages of Laser Cleaning over Acid Cleaning

Although the efficiency of laser cleaning cannot reach the same level as the acid cleaning process, it has obvious technical advantages in other aspects:

The acid cleaning method requires chemicals as consumables, so the unit cost is composed of equipment depreciation + consumables costs; laser cleaning in addition to the purchase of equipment does not require other consumables. The unit cost is the depreciation of equipment; therefore, the larger the scale of cleaning, the longer the years, and the lower the unit cost of laser cleaning.


The composition of the pickling production line requires a complex process, the ratio of pickling agents for different metal materials is not the same, so the conversion of the production line will require larger conversion costs, the short-term cleaning of a single metal material, can not be flexible changes. Laser cleaning there is no conversion costs: the same cleaning machine to switch the software parameters can be achieved one minute by cleaning steel, and the next minute by cleaning aluminum alloy effect. Convenient for enterprises to implement JIT flexible production.

 

With the introduction of China's “carbon peak, carbon neutral” policy in the past two years, the relevant documents and the requirements of the structural transformation and upgrading of the manufacturing industry are becoming more and more stringent, and environmental protection is increasingly important. Picking the production line of the environmental assessment report is also increasingly strict, the profit margin of the relevant enterprises is getting thinner and thinner. In turn, the support for high-tech increased. The overall environment is more favorable to laser cleaning.

 

Although the efficiency of 14.5 square meters / h still lags behind the pickling process, the technology path is not mature enough, but I believe that with the emergence of high-power laser cleaning equipment and advanced laser cleaning process iterative breakthroughs, laser cleaning will gradually replace the pickling process market.

History of Lasers

Image
  Lasers have been hailed as one of the great inventions of the twentieth century, following nuclear power, computers, and semiconductors, and have brought about a great technological breakthrough for mankind. The laser radiation produced by lasers is famous for being the "fastest blade", the "most accurate ruler" and the "brightest light". Nowadays, laser technology plays an important role in many fields such as medicine, the military industry, communications, and so on.   The birth of the laser is the result of the tireless efforts and arduous exploration of many scientists.   In 1917, Albert Einstein proposed the concept of "stimulated radiation", which laid the cornerstone for the theoretical foundation of lasers.   Although the theory of lasers had already been proposed at that time, the actual preparation of lasers was quite challenging. By the 1950s, with the progress of photon and microwave technology, the manufacture of an oscillator cap...

Automated laser welding improves MDM yields

Image
Hiring and training skilled personnel is not only costly, but in today's labor market, it is becoming increasingly difficult for companies to find and retain this talent. Automated laser welding systems dramatically reduce the need for skilled personnel. For example, once an engineer or technician has specified and stored all aspects of a welding application using the machine software, the operator can safely initiate the welding process with limited access to functions through the GUI.   Avoiding subjective judgment on the operator's part, combined with the use of in-situ vision, process monitoring, laser monitoring, and post-process validation features, provides consistent production, increased yields, and reduced scrap. Whenever there is any deviation from the specified limits in the process, the machine makes the necessary adjustments or stops the process and alerts the operator. This is clearly a benefit for any application. It would be especially beneficial when welding p...
