During long-term operation, the intake–exhaust valve ports on the compressor cylinder body are subjected to high pressure, elevated temperature, and continuous vibration. Over time, these ports become worn, scratched, and lose sealing capability, reducing compression efficiency.With a D70 port at a depth of 120 mm, the workspace is extremely narrow ...

Shaft rejoining is one of the most challenging mechanical repair techniques, requiring high precision and strict thermal control. Industrial shafts operate under heavy loads, continuous friction, and strong vibration; once a shaft breaks, it is often discarded and replaced—leading to high costs and production downtime. Traditional welding methods rarely achieve ...

Restoring pump impellers with metal 3D printing technology (Laser Metal Deposition – LMD, also known as Laser Cladding) is a modern method that rebuilds worn, eroded, or locally corroded parts by adding precise layers of metal material. This technology enables accurate layer-by-layer deposition to restore the original geometry of the ...

1. Global 3D Metal Printing Technology  3D metal printing is one of the most advanced manufacturing technologies today, widely applied across industries such as aerospace, automotive, oil & gas, energy, and healthcare.Developed countries like the U.S., Germany, Japan, and South Korea are leading the way in integrating Laser Cladding technology ...

In Laser Cladding technology, precise control of laser activation plays a vital role in surface quality, process efficiency, and equipment durability. To address this challenge, PHUONGDONG INDUSTRY has developed a specialized software solution: Auto Turn On/Off Laser, which enables automated laser on/off control based on G-code data. Software Overview Auto ...

Why Choosing the Right Laser Cladding Powder In Laser Cladding technology, the choice of cladding material—usually metal alloy powders—plays a crucial role in determining the durability, performance, and service life of components. Depending on working conditions such as abrasion, chemical corrosion, or high temperature, it is essential to select the ...

Laser heat treatment, also known as laser hardening, is an advanced surface treatment technology that uses a high-power laser beam to locally heat the surface of metal materials to hardening temperature. Thanks to the extremely rapid self-quenching ability of the base material, the surface layer becomes hardened without altering the ...

11. Can large components be repaired using Laser Cladding? Yes. With high-power laser systems and proper workpiece fixtures, Laser Cladding can be applied to large parts such as pump shafts, valve bodies, or industrial gears. However, the component’s size, weight, and the area needing repair should be carefully evaluated for ...

Clear and concise answers to help you better understand Laser Cladding – one of the most advanced surface restoration and coating technologies today. What is Laser Cladding? Laser Cladding is an advanced technology used to restore and enhance the surface of mechanical components. It works by applying metal powder or ...
