Introduction
Keyhole welding is a deep-penetration technique that uses focused energy — like lasers or plasma — to weld metals, and it’s being tested in hydrogen pipeline manufacturing.

🧠 What It Means
Keyhole welding creates precise, narrow welds ideal for pressurised hydrogen systems.
It helps ensure strong joints in high-stress environments like pipelines and tanks.
Laser and electron beam welding are common forms.
❗ Key Challenges
Hydrogen embrittlement can weaken welded joints.
Quality control must be extremely tight.
Requires specialised equipment and training.
🦁 Muzaffar’s Comment
“We’re literally welding the future together — hydrogen pipelines need perfection, and this is how we get there.
🦉 Sameer’s Comment
“This isn’t your average weld — keyhole welding gives hydrogen the tight seal it demands.”
