Certificate of Qualification 424A


A welder is a skilled tradesperson who specializes in welding various metals using heat and pressure to join them together. They use various welding techniques such as MIG, TIG, and stick welding to create structures, repair damage, and manufacture a wide range of products. Welders work in various industries, including manufacturing, construction, and shipbuilding, and they are required to read blueprints and specifications, perform measurements, and operate welding equipment and tools. They must also be familiar with safety protocols and regulations related to welding and take necessary precautions to avoid injury or damage to equipment.

Arc Welding

Arc welding, also known as stick welding, stands as the oldest and most economical welding technique, requiring fewer materials and equipment, and offering ease of learning. Achieving mastery in this skill demands dedication, continuous practice, sharp focus, and meticulous attention to detail to consistently produce robust and reliable welds.

MIG Welding

Metal Inert Gas (MIG) welding, alternatively referred to as Gas Metal Arc Welding (GMAW), involves creating an electric arc between a consumable MIG wire electrode and the workpiece metal to effectively merge the components. While it may incur higher costs in terms of materials and equipment, MIG welding delivers consistently precise and accurate welds.

TIG Welding 

TIG welding, or Tungsten Inert Gas welding, is renowned for its versatility and stands as the most flexible technique among the three mentioned methods, resulting in welds of the highest quality. Frequently utilized for both extensive and intricate projects that necessitate precise control, TIG welding excels despite its complexity. It particularly shines when working with thinner materials, producing tidy welds that require minimal finishing.
