SMAW ON ALUMINIUN,CAST IRON AND STAINLESS STEELR

Introduction

Shielded Metal Arc Welding (SMAW) is a welding process that uses an electric arc and coated electrodes to join metals. It is portable, simple, and commonly used in industries.

SMAW on Aluminium

Aluminium is lightweight, corrosion resistant, and conducts heat quickly. SMAW on aluminium requires special electrodes and clean surfaces.

SMAW on Cast Iron

Cast iron contains high carbon and is brittle, so it cracks easily during welding.

SMAW on Stainless Steel

Stainless steel is strong and resistant to rust and corrosion.

PREVENTIVE MAINTENANCE

Preventive Maintenance (PM) Level 4 is the most advanced and comprehensive stage in a multi-tiered PM program used in manufacturing technology. This level focuses on deep inspections, diagnostics, and overhauls to ensure long-term equipment reliability and performance. It often involves specialized personnel, advanced tools, and predictive technologies.


ASSEMBY OF MANUFACTURED/COMPONENTS PARTS

IMAGE

Assembly is the process of putting together individual manufactured parts or components to form a final product, sub-assembly, or system. It is a key phase in manufacturing and production.


SPOT WELDING

This module describes employable and practicable skills, knowledge and right attitudes required by the learner to prepare the workplace for spot welding, weld the work piece and conduct finishing activities. The content provided in this course is package reserved for a learner pursuing TVET certificate IV in manufacturing technology. Graduates at this level will have knowledge and skills for spot welding and community involvement and further leaning.

COST ESTIMATION

cost estimation summary for Level Four Manufacturing Technology, focusing on advanced manufacturing processes such as precision assembly, testing, and final production stages. This analysis considers global best practices and emerging technologies in cost estimation.

Lathe Machine Operation

This course introduces learners to the lathe machine, one of the most important and widely used machines in manufacturing technology. Students will gain both theoretical knowledge and practical skills in operating, maintaining, and applying the lathe for different machining processes.

The course begins with the history, types, and parts of the lathe machine, explaining their functions and importance. Students will learn about the working principle, which is based on the rotation of the workpiece against a cutting tool to remove material.
