 Advanced Welding - GMAW and GTAW           

Advanced Welding entails grooved welds on Carbon Steel Plate – 80 schedule pipe, 2" and 4" stainless pipe using Tungsen Inert Gas Welding and Metal Inert Gas Welding. It also includes measurement, layout, blueprint reading, isometric and P & ID reading, safe work habits, basic electricity, materials and metallurgy, quality control, inspection methodology, communications. Successful candidates are code certified in accordance with ASME Section IX.

Note:    Persons desirous of doing the Advanced Welding must first complete the Carbon Steel Welding Programme.
