Welding and fabrication are two closely related processes that are used to create metal products. Welding is the process of joining two or more pieces of metal together by melting them and allowing them to cool and resolidify as a single piece. Fabrication is the process of shaping and forming metal into desired shapes and sizes.

Welding is a critical part of the fabrication process, as it is used to join the different pieces of metal together. However, welding is not the only process involved in fabrication. Other processes, such as cutting, bending, and machining, are also used to create finished metal products.

Welding and fabrication are used in a wide variety of industries, including construction, manufacturing, and transportation. Some common examples of welded and fabricated products include:

• Structural steel beams
• Ships and boats
• Aircraft
• Cars and trucks
• Bridges and buildings
• Oil and gas pipelines
• Power generation plants
• Food processing equipment
• Medical devices

Welding and fabrication are essential skills for many tradespeople, including welders, metal fabricators, boilermakers, and pipefitters. These tradespeople are responsible for creating the metal products that we rely on every day.

Here are some of the most common welding processes used in fabrication:

• Gas metal arc welding (GMAW), also known as MIG welding, is a semi-automatic process that uses a consumable wire electrode to create a weld. GMAW is one of the most popular welding processes, as it is relatively easy to learn and can be used to weld a wide variety of metals.
• Shielded metal arc welding (SMAW), also known as stick welding, is a manual arc welding process that uses a consumable electrode rod to create a weld. SMAW is a versatile welding process that can be used to weld a wide variety of metals, including steel, stainless steel, and cast iron.
• Gas tungsten arc welding (GTAW), also known as TIG welding, is a manual arc welding process that uses a non-consumable tungsten electrode to create a weld. GTAW is a precision welding process that is often used to weld thin metals and to create high-quality welds.
