Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. TIG stands for Tungsten Inert Gas, after the tungsten electrode, and the sheath of inert gas (argon or an argon mixture) surrounding it. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapours known as a plasma


  • Understand the equipment, process and tungsten inert gas welding technique
  • Operate a portable grinder
  • Carry out:
  • Flat position welding
  • Straight run welding
  • Butt-joint welding
  • Fillet joint welding
  • Vertical up but-joint welding
  • Horizontal butt-joint welding
  • Weld a pipe vertical/horizontal in position
  • Setting of the different current settings on types of welds
  • General Welding Safety and Health

Purpose of the Course.

-To equip students with the knowledge to use TIG welding  to weld copper, titanium, even two dissimilar metals, and also making tricky welds such as curves, or welds on round things..

-To provide the students with the ability to soft start and soft stop the heat in the TIG welding process

-To train students how to use a TIG welding machine, welding rods, filler materials and electrodes and also to be able to choose the electrode, grind the electrode and inserting the electrode into its collet

-The successful participant will be able to solve more advanced welding tasks in all positions within a metal work environment in order to improve productivity and quality within the workplace and improve his won employability.

Career Benefits

The learner will achieve a level of skills which enhances his status in a company or will lead to a formal employment. Upon completion of this course, the student will be able to perform general entry level structural welding in fabrication shop, machine shop, petrochemical, power plant and refineries. At the completion of the course each student will receive a certificate of completion recognized and certified by the relevant local and international stakeholders.

Assessment Method

Throughout the training, continuous assessments are carried out by the way of written tests and practical assignments in order to monitor progress of the trainee and effectiveness of learning.
