Lighthouse Project in Singapore: Box Components Take Shape with Gantry Dual-Wire Welding

Release time:

16 Jan,2026

Box components for Singapore's Linhai Lighthouse 7-story wafer fab are being finished with gantry dual-wire welding, a efficient method that strengthens the building’s structural core.

Look at the factory scene – it’s the production of box components for Singapore's Linhai Lighthouse 7-story wafer fab production building. The key process here is gantry dual-wire capping, a practical welding method that’s hard at work.

What’s happening in the process?

Gantry dual-wire welding uses an automated gantry system with two welding wires working together. The dual shield technology combines flux-cored wire and shielding gas, creating a stable arc that melts metal evenly. The "capping" step is the final weld pass, leveling the surface of the box components to finish their structure. It’s a precise, efficient way to join thick steel plates without messy defects.

Why does this matter for the project?

The box components are hollow, box-shaped steel parts that act as the building’s structural backbone. They need to be strong enough to support the 7-story fab and heavy equipment inside.

Dual-wire welding boosts efficiency – it works faster than single-wire methods while ensuring deep penetration. This means the components are durable and can handle the fab’s unique load demands.

The process reduces distortion and cleans up easily, keeping production on track for the new wafer fab’s completion.

For a wafer fab, structural stability is non-negotiable – sensitive manufacturing equipment can’t tolerate vibrations or structural shifts. These well-welded box components will form the building’s reliable frame, laying the groundwork for the high-tech production ahead.
