Current status of development of laser welding water drill bits in China Ⅰ

With the rapid development of China's domestic economy and the rapid growth of its construction and engineering industries, China has become a major infrastructure construction powerhouse. Driven by this trend, China's diamond laser-welded drill bit industry has also seen significant growth. This includes water drill bits for stone, concrete water drill bits, and dry drill bits for construction.

 

This article, based on this background and from the perspective of a diamond tool professional, briefly analyzes the development of laser-welded diamond water-jet drill bits in China.

 

 

1. The Impact of the Domestic Consumer Ecosystem

The domestic consumer ecosystem makes it difficult for the domestic market to become a major market for laser welding drill bits. The main reasons are as follows:

• Demand for mid- and low-end products dominates the domestic drill bit market: In the domestic drill bit market, many applications such as construction and home renovation require practical, basic drill bits. Domestic brands primarily focus on the mid- and low-end market. For example, drill bits made of ordinary materials can meet basic drilling needs, and consumers do not need to bear the additional cost of laser welding.
• Consumers are highly price-sensitive: Chinese consumers are highly concerned about the price of drill bits. Due to complex manufacturing technology and high equipment costs, laser welding drill bits are significantly more expensive than those using traditional processes such as high-frequency welding. When the performance difference is not extremely significant, price guidance will lead consumers to choose low-priced drill bits using traditional processes to maximize cost-effectiveness.
• Product design innovation is prioritized less: The advantages of laser welding drill bits lie in welding strength, accuracy, and stability. However, many domestic applications for drill bits do not require high-precision welding. Consumers prioritize functional elements like chip removal, heat dissipation, and tooth profile when designing water drill bits, and are less sensitive to the quality improvements offered by advanced welding processes like laser welding.
• Market competition leads to a lack of motivation for process upgrades: Due to fierce competition in the mid- and low-end segments of the domestic water drill bit market, companies often prioritize cost control and price competition to secure market share. This reduces the incentive for companies to invest in R&D and promote laser welding technology, indirectly preventing laser-welded water drill bits from becoming mainstream products in the domestic market.

 

2. The Development History of Laser Welded Road Sheets in China Offers Instructional Value.

Since laser welded road sheeting predates the development of water drill bits, let's first examine its development history in China:

• Technology Introduction and Exploration Stage: At the end of the 20th century, global advances in laser welding technology prompted domestic companies and research institutions to begin considering the feasibility of this technology in the production of road sheeting and other cutting tools. However, due to limitations in laser power, cost, and process maturity, this stage primarily focused on technology tracking and preliminary testing. Laser welded road sheeting in China was essentially in the concept introduction and small-scale technical verification stages.
• Initial Application Development Stage: Entering the 21st century, the government strengthened its support for the laser industry. Policies such as the "Guiding Opinions on Promoting the Development of the Laser Industry" issued in 2018 promoted the application of laser welding technology in the manufacturing industry, accelerating the development of the domestic laser welded road sheeting industry. As the technological capabilities of local companies such as HGLASER increased, diamond tool companies began to apply laser welding technology to road sheeting production, and this product gradually gained prominence in fields such as construction.
• Technical Optimization and Market Expansion: In recent years, domestic laser welding equipment manufacturing has significantly advanced. Companies like Han's Laser have steadily increased their market share. The quality and efficiency of laser-welded road sheeting products have continued to improve, while production costs have decreased. These products are increasingly used in large-scale projects like bridges and tunnels, and market demand has steadily expanded. Meanwhile, domestic companies have participated in the development of a series of national and industry standards related to laser-welded road sheeting, further regulating the industry's development.
• The development history of laser-welded road sheeting, a product similar in process and user group to diamond tools, offers valuable insights for the development of laser-welded water drill bits. Laser-welded water drill bits are currently in their early stages of application and development in China.
