Answer :
Final answer:
The most common and simplest type of welding today is Stick welding, known for its versatility, cost-effectiveness, and being a fundamental skill for metal fabrication. The correct answer is c) Stick welding.
Explanation:
The most common and simplest type of welding today is c) Stick welding. Stick welding, also known as Shielded Metal Arc Welding (SMAW), is a process that uses an electric current to heat and melt a metal stick, thereby fusing two pieces of metal together. This method is widely regarded for its simplicity and cost-effectiveness, making it a popular choice for both professionals and hobbyists. Unlike more complex methods such as TIG (Tungsten Inert Gas) welding, MIG (Metal Inert Gas) welding, and Plasma welding, Stick welding does not require a gas supply and it can be used with a variety of metals, including iron, steel, aluminum, and copper. Its versatility and ease of use ensure that Stick welding remains a fundamental skill in the fabrication of metal structures and is often the first type of welding that beginners learn.
