Jeff Grill

Hi, I’m Jeff Grill — a certified welding expert and instructor based in Long Island, NY.

With over three decades in the industry, I’m passionate about combining theoretical knowledge with hands-on experience to train the next generation of skilled welders.

I specialize in all forms of arc welding, including GMAW, GTAW, GMAW, FCAW & SAW. But my experience isn’t limited to just those—I’m also knowledgeable in oxyfuel gas welding and plasma arc cutting.

My years as a welding inspector and supervisor have honed my ability to ensure the highest standards in welding quality and safety, making me adept at executing and overseeing complex welding operations.
