We're talking about the core techniques that form the foundation of most welding applications. Let's break down the common ones:

• Shielded Metal Arc Welding (SMAW): This is probably the first process you'll learn, also known as stick welding. It's the most straightforward and versatile method, making it ideal for beginners. SMAW uses a consumable electrode (a metal rod coated with flux) to create an electric arc between the electrode and the workpiece. The arc melts the base metal and the electrode, forming a weld pool. The flux coating on the electrode provides a shielding gas that protects the weld from atmospheric contamination. This process is great for a wide range of materials and positions, making it a staple in various industries. You'll learn how to strike an arc, maintain the arc length, and move the electrode to create a strong and consistent weld. It’s relatively simple to learn but requires practice to master. Get ready to experiment with different electrode types and settings to achieve the desired weld quality. Safety is critical with SMAW, as the intense heat and bright light can be harmful. Always wear proper PPE, including a welding helmet, gloves, and protective clothing.
• Gas Metal Arc Welding (GMAW): Often called MIG welding, this is a semi-automatic process that uses a continuous wire electrode fed through a welding gun. A shielding gas (usually argon or a mixture of argon and carbon dioxide) is used to protect the weld pool from contamination. GMAW is known for its speed and efficiency, making it suitable for high-volume production. It's also relatively easy to learn, producing cleaner welds with less slag than SMAW. You'll learn about different wire types, shielding gases, and welding parameters. This process is widely used in automotive, construction, and manufacturing industries. The continuous wire feed allows for longer welds without stopping, making it faster than stick welding. GMAW produces minimal spatter, resulting in cleaner welds. Mastering this process will give you a significant edge in various engineering applications.
• Gas Tungsten Arc Welding (GTAW): Commonly known as TIG welding, this is a more precise process that uses a non-consumable tungsten electrode to create the arc. A shielding gas (usually argon) protects the weld pool. TIG welding is known for its high-quality welds and is often used for critical applications, such as welding stainless steel or aluminum. The welder controls the filler metal separately, allowing for greater control over the weld bead. It requires more skill and practice, but the results are exceptional. You'll learn about different tungsten electrodes, shielding gases, and welding parameters. TIG welding is commonly used in aerospace, food processing, and art installations, where aesthetic appeal is as important as structural integrity. This process provides superior control and produces exceptionally clean, high-quality welds. It's the go-to process when appearance and precision are paramount.

These three processes are the cornerstones of your initial welding education. Each has its strengths and weaknesses, and understanding their differences is crucial for selecting the right process for a specific application. In your iWeld Workshop, you'll get hands-on experience with each of these, so be prepared to get your hands dirty and learn the ins and outs of each technique!
