What do you still hope to achieve/learn in this field? More NDT traing, especially Phased Array Ultrasound. Phased Array Ultrasound is very "Star Trek" future sci-fi stuff. Allows you to look right through solid metal and see a picture of what is going on inside in real time.

Something interesting about this subject that others may not know: People think of steel as hard, but the more you learn the more you realize it is more like clay than stone.

Something controversial or provocative about this subject I see no barrier between trade skills. Cabinetry, glassblowing, jewelry, blacksmithing, pottery, metal-spinning, machining, cooking, knifemaking, welding... They are all just variations on a theme, with 3 parameters : Materials, Skills, and Equipment. You can never have too many tools in your toolbox. I love having options, and sometimes welding isn't the right way to go and a rivet is better.

What do you like about this subject? All fabrication is based on using one or more of these processes to get your part made. Addition - Welding, Soldering, Brazing... Subtraction - Milling, Turning, Drilling, Sawing, Planing, Grinding, Punching, Shearing... Forming - Bending, Forging, Drawing, Rolling, Stamping, Spinning, Swaging... The trick is to know which one to use when.
