DSI – Pulse Laser Welding

Shaping the Future of Industrial Repair with Pulse Laser Welding

DSI Malaysia partners with leading companies across diverse industries to deliver precision-driven, high-performance pulse laser welding solutions.

Overview

DSI SYMTRACE SDN BHD is a strategic joint venture between DSI Thailand and SYMTRACE, established to introduce advanced pulsed laser welding technology to Malaysia. With our branch workshop in Shah Alam, Malaysia we provide high precision, sustainable repair solutions for critical industries including oil & gas, power generation, mold & die based industry and petrochemicals. Leveraging over 25 years of Thai-German expertise from DSI Laser Service (Thailand) Co. Ltd. the headquarters of the DSI Group, we specialize in the metallic rebuilt using pulsed laser welding powered by ALPHA LASER GmbH. This technology is redefining industry standards in repair and restoration.

Products & Services

Pulse Laser Welding brings unmatched precision, zero distortion, and full metallurgical bonding, making it the ultimate solution for repairing and upgrading rotating equipment and mold & die tools.

Pulse Laser Welding is not just another welding process. it’s a game-changing technology that allows industries to push the limits of equipment reliability, performance, and lifespan. At DSI Malaysia, our certified welding experts combine advanced laser systems, proprietary filler wires, and decades of proven field experience to deliver precision repairs with no compromise.

INDUSTRY FOCUS

Oil & Gas Industry

DSI Pulse Laser Welding (PLW) delivers distortion-free, metallurgically bonded repairs with micron-level accuracy perfect for sealing areas, shafts, impellers, and housings. Unlike conventional welding or coating, PLW introduces minimal heat, ensuring components retain their geometry and mechanical integrity. It also enables dissimilar alloy welding, such as Inconel on stainless steel, for superior corrosion resistance in aggressive environments.

By restoring equipment to OEM-level standards, PLW reduces replacement costs, extends service life, and shortens turnaround during shutdowns.

INDUSTRY FOCUS

Power Generation Industry

In the power generation sector, turbines, rotors, and diaphragms operate under continuous high stress, heat, and vibration. Any distortion or surface wear can impact efficiency, leading to costly downtime and reduced output. Pulse Laser Welding (PLW) offers a precision driven repair method that restores critical turbine and generator components with no measurable distortion. Each laser pulse delivers high peak power with minimal overall heat, protecting the base material while ensuring full metallurgical bonding. This makes PLW ideal for repairing thrust collars, sealing surfaces, casings, and other tight-tolerance areas.

INDUSTRY FOCUS

Heavy Industry

Heavy industries such as petrochemical plants, paper mills, and marine operations rely on large, high-value equipment that operates under constant mechanical stress and corrosive environments.

Pulse Laser Welding (PLW) provides a proven, long-term repair solution for these sectors. PLW achieves distortion free build-up and full metallurgical bonding, ensuring repairs restore parts to OEM-level performance. Unlike coatings or overlays, PLW is a true welding process.

INDUSTRY FOCUS

Mold & Dies Industry

The Mold & Die industry demands repairs that maintain precision geometry and surface integrity. Even minor defects such as cracks, worn edges, or surface pitting can compromise product quality.

Pulse Laser Welding (PLW) provides a lasting solution by depositing layers of filler material with micron-level accuracy and no measurable distortion. This is not a temporary patch. PLW achieves full metallurgical bonding, restoring the tool to almost original level quality and durability and at times even better.
