Thinking about a career in the skilled trades? This PTTI guide explains the difference between MIG, TIG, Stick, and Flux-Core welding in simple language, so you know exactly what each process does before you choose a program. You will learn how each method feeds filler metal and shields the weld, which one is easiest for beginners, which works best outdoors or on thick steel, and which welding process to learn first. The guide also shows how welders in the Philadelphia region use all four every day in shipbuilding, structural steel, metal fabrication, and pipefitting work across the city, surrounding Pennsylvania communities, and South Jersey. Written for high school students, career changers, and adult learners looking for an alternative to a four-year degree, it connects each welding process to real job roles and explains why employers value welders trained in more than one method. Philadelphia Technician Training Institute offers hands-on welding training in Philadelphia on industry-standard equipment, taught by instructors who have worked in the field, with admissions and financial aid support available.
