Our Training Courses
At Nationwide Welding Institute, we offer a full range of certified training courses designed for beginners, experienced welders, and professionals looking to upskill or specialise.
TIG Welding
Master Precision Welding
TIG welding uses a non-consumable tungsten electrode to produce clean, high-quality welds. The process ensures precision through an inert shielding gas that protects the weld area.
Ideal for stainless steel, aluminium, and high-spec applications.
MIG/MAG Welding
Versatile and Industry-Focused
This semi-automated process is widely used across fabrication, shipbuilding, and heavy industry. A filler wire melts to form part of the weld pool, shielded by gas for a strong, clean finish.
Perfect for high-volume production and structural work.
MMA Welding
Reliable and Flexible
MMA (Manual Metal Arc) welding is one of the most commonly used welding processes worldwide. It’s valued for its adaptability and is ideal for fabrication, repair, and site work.
Great for beginners and professionals alike.
Orbital Welding
Precision in Motion
This automated process is used for welding pipes and tubes, producing consistent, high-quality joints. The enclosed weld head and power control system ensure accuracy every time.
Essential for industries like pharmaceuticals, food, and aerospace.
Manual Handling
Work Safely and Confidently
Gain the skills to assess risks and safely lift and move materials in the workplace. Learn proper technique in line with the Safety, Health and Welfare at Work Regulations 2007.
Ideal for anyone handling loads as part of their job.
Abrasive Wheels
Safe and Skilled Operation
Learn how to correctly mount, set, and use abrasive wheels for grinding and cutting tasks. This certified course combines theory and practical skills for safe tool use.
Essential for tradespeople and workshop staff.
Polyethylene Welding
Efficient and Cost-Effective Techniques
Used across gas, water, electrical, and waste industries, Polyethylene Welding is an increasingly popular and affordable joining method. NWI provides full training and certification in this growing field.
Excellent for construction and utility professionals.
NDT – Non-Destructive Testing
Inspect Without Damage
Learn to test materials and structures using non-invasive methods such as Magnetic Particle, Radiographic, and Ultrasonic Testing.
Crucial for ensuring safety, integrity, and compliance in engineering.
