Behind Every Reliable Mooring System: GLEN's Commitment to Welding Excellence

At GLEN, the reliability of mooring and berthing equipment begins with a rigorous manufacturing foundation.

For critical load-bearing structures, welding quality is not only a manufacturing process — it is a key factor that directly affects equipment safety, durability, and long-term performance.

To further strengthen our welding capability, GLEN is conducting a comprehensive Welding Procedure Qualification (WPS) program in accordance with DNV requirements. 

The qualification covers multiple welding processes and structural configurations, including:
🔹 135-GMAW (Gas Metal Arc Welding) and 111-SMAW (Shielded Metal Arc Welding)
🔹 Butt welds and full penetration T-joints
🔹 High-strength structural steels including Q355E and 35CrMo

During the qualification process, the welded test specimens undergo a series of rigorous inspections and mechanical tests, including:

✔️ Visual Testing (VT)
✔️ Magnetic Particle Testing (MT)
✔️ Radiographic Testing (RT)
✔️ Tensile Testing
✔️ Impact Testing at -40°C
✔️ Bend Testing
✔️ Macro Examination
✔️ Hardness Testing

These evaluations verify the weld integrity, mechanical properties, low-temperature toughness, and overall performance of the qualified welding procedures.

Quality is built into every detail — from engineering design and material selection to manufacturing processes and final inspection.

By establishing a reliable welding qualification system, GLEN continues to enhance its manufacturing capabilities for demanding applications in LNG, Oil & Gas & Offshore Energy Projects.
