"High-power Laser Welding Equipment Integration and Key Technology R&D" Project Accepted in Chongqing

[China Aluminum Industry Network] The scientific and technological breakthrough “High-power laser welding equipment integration and key technology R&D” project undertaken by the Institute of Optics and Mechanics, Chongqing Institute of Science and Technology was accepted by experts.

In view of the three key technical difficulties of high-power welding machine tool optical systems, mechanical components, and servo systems, the Chongqing Institute of Optics and Mechanics actively uses the advanced technology research and development methods of British TWI and German Preetsch, and cooperates with Chongqing Applied Technology Co., Ltd. Technical breakthroughs, successful realization of technical research and development and domestic design of temperature control, water cooling, air knife, reflection, focusing and other parts of the 4500-watt CO2 laser welding processing head, completion of hardware and software development of laser and welding machine integrated control system, and conquer the laser Gaussian beam ability focusing technology problems, formed a new test device, the laser welding depth of 8mm, focal length of 200mm, to solve the technical difficulties that exist in the industry, opened the western countries of the technical blockade of advanced laser welding equipment, and have Product marketing capabilities. The project has obtained 2 patents for utility model patents and 2 papers for publication. It has successfully established a high-power laser welding machine test platform and demonstration base. The R&D equipment has provided R&D and technical services for more than 10 companies, showing good market application. prospect.

Chongqing Institute of Optics and Mechanics is a scientific research institute specializing in high-power laser application technology research, laser processing service and laser product research and development in Chongqing and even in the southwest region. Over the past 30 years, it has successfully developed a variety of laser products and laser processing equipment. And put on the market, has accumulated a wealth of laser equipment development, system integration, project management and operational experience, laser application technology R & D strength in Chongqing and even the entire southwest region are in an industry-leading position.

 DTH Hammer products offers a wide range of quality, versatile DTH hammers to interchangeable, or replace a number of leading industry manufacturers. Hammers are available for down hole and blast hole, water well, gas, mining  applications and use in nearly all ground conditions. Most DTH hammers are designed for use with the industry's most common rock drill bits shank types 


DTH hammer Design Principles

To pursuit smooth operation and reliability.

 

Advantages

1.The good seal effect eliminates the problems caused by water and flushing entering into the inner cylinder of hammer.

2.Simple structure ,easy operation and maintenance.
