Metalworking is the process of shaping and joining metal to create tools, structures, and machinery used in various industries like construction, automotive, and manufacturing. TESDA’s Training Regulations (TRs) for metalworking ensure that individuals gain the proper skills and knowledge to become competent metalworkers and welders who meet national and industry standards.
The TESDA TRs for metalworking focus on welding processes, metal fabrication, and safe work practices. Two key qualifications under this sector are:
SMAW (Shielded Metal Arc Welding) : This teaches learners how to perform welding on carbon steel plates and pipes using a covered electrode. It includes interpreting drawings, preparing materials, and applying proper welding techniques safely and efficiently.
MMAW (Manual Metal Arc Welding): Often used interchangeably with SMAW, this process is one of the most common welding techniques. Training involves assembling and welding metal structures, maintaining welding equipment, and following safety standards and welding procedures.
These programs aim to develop skilled workers who can meet the demands of the construction, shipbuilding, and manufacturing industries. By following TESDA’s TRs, trainees become qualified for local and overseas employment. The training helps ensure the quality, safety, and durability of metal structures by teaching welders to work precisely and efficiently.
Upon completing the course and passing the assessment, trainees are awarded a National Certificate (NC) by TESDA—either NC I or NC II, depending on the level of competency. This certification is widely recognized by employers across the Philippines and abroad.
SMAW NC I is the starting point for those who want to learn basic welding skills.
You will learn how to weld flat metal plates safely and correctly.

SMAW NC II takes your skills to the next level.
You will learn to weld plates in more difficult positions and basic welding on pipes.
Welding carbon steel plates in all positions
Basic pipe welding in a rotating position
Working with different welding electrodes
Interpreting more detailed technical drawings
Following welding codes and standards

Plates: 1G, 2G, 3G, 4G (Overhead)
Pipe: 1G (Rolling position)
Holder of SMAW NC I certification (recommended)
Or welding experience with assessment pass
Approx. 268 hours (similar to NC I)
Plate welder
Structural welder
Fabrication welder
Pipe welding assistant
SMAW NC III is for welders who want to specialize in pipe welding, which is needed in oil and gas, shipbuilding, and heavy industry.
Pipe welding is much harder because you often weld around the pipe, without moving the pipe itself.
Weld carbon steel pipes in fixed horizontal and vertical positions
Prepare pipe joints (fitting, beveling)
Perform high-quality welds with strict standards
Conduct inspections for pipe welds (check for cracks, porosity, etc.)
Follow more detailed welding procedures and plans
Pipe welding:
2G (Horizontal Fixed)
5G (Vertical Fixed)
Holder of SMAW NC II
Experienced welders (with TESDA assessment approval)
Approx. 120 hours (about 1 to 2 months full-time)
Pipe welder (refineries, power plants)
Pipeline welder (oil and gas industry)
Boiler welder (factories, ships)
High-pressure pipe welder
SMAW NC IV is for experienced welders who want to move up into leadership, inspection, or quality control roles.
You won’t just weld you will lead welding teams, check the quality of work, and train new welders.
Plan welding work for large projects
Supervise welders at construction sites
Inspect welding work for quality and safety
Understand international welding codes and standards
Write welding reports and documentation
Perform training and assessments for welders
Holder of SMAW NC III
Significant work experience in welding
Varies depending on the training center and program
Welding supervisor
Welding inspector
Quality control technician (welding)
Welding instructor or trainer
SMAW welders are in high demand in countries like:
Canada
Australia
Japan
Saudi Arabia
United Arab Emirates
USA
Qatar
This is the entry-level certification. It covers basic welding operations using MMAW on carbon steel plates in flat position.
Performing basic welding work using MMAW
Preparing welding materials and tools
Applying safety practices in the workplace
Welding plate metals in flat position (1G)
Typically 2–4 months of hands-on training and classroom learning at TESDA-accredited institutions or training centers.
Entry-level positions in construction and manufacturing.
Jobs as junior welder, metal fabricator, or maintenance assistant.
Written exam on welding theory (e.g., safety, equipment knowledge).
Practical welding test, where candidates demonstrate their ability to complete simple welds.
This level builds upon the foundation established in NC I and involves more complex welding skills. NC II covers welding in multiple positions and introduces advanced techniques like multi-pass welding. Successful completion of NC I is a prerequisite for this level.
Welding carbon steel plates in:
Flat (1G)
Horizontal (2G)
Vertical (3G)
Overhead (4G)
Performing quality checks
Interpreting welding symbols and blueprints
Maintaining welding equipment
3–6 months of practical and theoretical training.
Jobs as welders in construction, shipbuilding, and manufacturing.
Ability to work on larger projects and move up to supervisory roles.
Written exam covering advanced welding principles, safety practices, and quality standards.
Practical assessment where candidates must complete welds in multiple positions, demonstrating proficiency in flat, horizontal, vertical, and overhead positions.
NC III is intended for those who want to work on more advanced welding projects, including welding pipework and joining thicker materials. This level is often required for more technical, high-skilled welding positions.
Welding carbon steel plates and pipes in all positions:
Plate: 1G, 2G, 3G, 4G
Pipe: 1G, 2G, 5G, 6G
Applying advanced welding techniques
Following stricter quality and safety standards
Conducting basic troubleshooting of welding defects
Usually 6–12 months, depending on the complexity of the training center's program and student proficiency.
High-paying welding jobs in heavy industries like oil & gas, construction, and shipbuilding.
Employment as senior welder, welding inspector, or pipeline welder.
Written exam on advanced welding concepts, metallurgy, quality control, and safety.
Practical assessment where candidates complete pipe and plate welds, demonstrating proficiency in all positions.
NC IV is the highest certification for MMAW and is aimed at experienced welders looking to take on leadership or training roles. This level covers welding management, teaching welding techniques, and ensuring compliance with codes and regulations in the workplace.
