To promote transformation and upgrading, laser + construction machinery can be expected in the future

According to the industry statistics of China Construction Machinery Industry Association, the 26 main engine manufacturing enterprises included in the statistics from January to June 2021 sold a total of 223,833 sets of various excavation machinery products, an increase of 31.3% year-on-year. From the perspective of market structure, excavators occupy an absolute mainstream position in the market of construction machinery and equipment. In addition, the National IV emission standard will be implemented in December 2022, which will accelerate the process of upgrading of construction machinery. Based on this, laser processing technology, as a new and efficient tool, has become an important tool to promote the transformation and upgrading of the construction machinery industry. Mr. Wu Rangda, President of Pentium Laser (Wenzhou) Co., Ltd., was invited to participate in the "China Laser Industry" magazine unit visit and discuss with experts in the industry how laser technology empowers the construction machinery industry. Laser + construction machinery has great potential. At present, lasers are rapidly penetrating into more downstream sectors. With the recent investment in new infrastructure in China, the construction machinery and other industries have ushered in huge development space. The "high-precision" characteristics displayed by laser processing technology just fit the needs of the construction machinery manufacturing industry, and contribute to the realization of intelligent manufacturing in China. "Laser processing technology fits the modern manufacturing concept of high precision, high efficiency, energy saving and environmental protection. It has excellent material compatibility, process controllability and quality reliability. It is widely used in various machinery manufacturing and processing, and has obvious advantages and development prospects. Laser cutting, laser welding, laser cladding and other technologies all play an important role in the field of construction machinery." Wu Rangda, President of Pentium Laser (Wenzhou) Co., Ltd. pointed out. For example, the laser cutting and cutting-welding process highlights the core position in the production of construction machinery products, accounting for more than 60% of the workload of structural parts. After laser cutting, the cutting edge is smooth and oxide-free, and generally can be assembled directly without reprocessing, thus greatly improving production efficiency and reducing labor costs. Xugong Group, Sany Heavy Industry, Zoomlion, Shanzhong Group, Lingong, Liugong and other large construction machinery manufacturers have introduced laser cutting processing systems into the production and manufacturing process.
