The course is generally divided into Trade Theory (the science and knowledge) and Trade Practical (the hands-on skill development), along with supporting subjects.
This is the most time-intensive component, involving continuous practice in the workshop.
Safety and Tools:
Workshop Safety: Strict adherence to safety practices in welding (PPE, fire prevention, ventilation).
First Aid: Handling minor burns, cuts, and electric shock.
Tools: Proper selection, use, and maintenance of welding tools (tongs, chipping hammer, wire brush, measuring tools, etc.).
Welding Processes:
Shielded Metal Arc Welding (SMAW / Stick Welding):
Identification and selection of various electrodes (e.g., E6010, E7018).
Preparation of welding joints (square butt, lap, tee, corner, etc.).
Practice welding in all positions: Flat (1G/1F), Horizontal (2G/2F), Vertical (3G/3F), and Overhead (4G/4F).
Gas Welding (Oxy-Acetylene Welding - OAW):
Setting up gas welding equipment, safety in handling cylinders and regulators.
Practice on straight bead, corner, and lap joints.
Cutting and Preparation:
Thermal Cutting: Techniques for Oxy-Acetylene Cutting (OAC) for ferrous metals.
Grinding and Bevelling: Preparing and cleaning metal surfaces before welding.
Inspection and Testing:
Visual inspection of welds for defects (undercut, porosity, lack of fusion).
Practice on simple destructive testing (e.g., bend tests, nick-break tests).
This module covers the necessary technical background for the practical work.
Welding Fundamentals:
Classification of welding processes and their applications.
Welding positions and standard joint nomenclature.
Understanding the properties of metals (ferrous and non-ferrous).
Welding Machines and Equipment:
Working principle of AC and DC welding machines.
Understanding electrode coatings and their functions.
Arc length, polarity, current, and voltage control.
Gas Welding Theory:
Types of flames (neutral, oxidizing, carburizing) and their uses.
Filler metals and fluxes used in gas welding.
Welding Defects:
Causes, identification, and remedies for common welding defects (cracks, distortion, spatter).
Basic Metallurgy:
Effects of heat on metals during the welding process.
These subjects provide supporting skills essential for a welder.
Workshop Calculation & Science (WCS): Basic applied mathematics related to the trade (e.g., units, area, volume, fractions, material density).
Engineering Drawing (ED): Interpretation of welding symbols on blueprints and basic sketching of joint designs.
Employability Skills: Basic communication, computer literacy, and environmental concepts.
This diploma prepares you to work as an entry-level Welder or Fabricator in construction, manufacturing, automobile repair, and general metal fabrication workshops.
