My Teaching Journey

Between 2012 and 2020, I dedicated my time to teaching the art and science of welding, giving me immense pleasure and a new passion for teaching.

I’m the proud owner of, a publication that reaches over 2 million eager learners from around the globe every year. I’ve poured my passion for welding into each article, tutorial, and resource you’ll find on that platform.

My Teaching Philosophy

What sets me apart as an instructor is my philosophy that understanding the ‘why’ behind each welding process is just as crucial as mastering the ‘how.’

I balance theoretical knowledge with hands-on experience, ensuring that my students know how to execute a weld and understand the metallurgy and physics behind it.

This holistic approach empowers them to troubleshoot issues on their own and adapt to different welding scenarios.
