Course Description
The demand for skilled welders is growing in world, and this Welding Techniques and Technologies Program offers superior training and a pathway into the trade. Our welding program stands out for its excellent instructors, superior facilities and strong reputation among employers. You'll get a thorough, practical education in the most current welding techniques and theories, preparing you for a welding career with good pay, benefits and career prospects.
Please note that this course is basic course in this category and conducted theoretically. If you want a theory mixed with theory and practice, we need to conduct through our solution partner when we have minimum 4 participants.
