### 1. Shielded Metal Arc Welding (SMAW) – Stick Welding
One of the oldest and most widely used welding methods, Shielded Metal Arc Welding, commonly referred to as stick welding, uses a consumable electrode coated in flux to lay the weld. The flux coating disintegrates during welding, producing a shielding gas that protects the weld pool from contamination.
**Key features:**
- Versatile and effective for outdoor and indoor applications
- Suitable for welding thick and heavy materials
- Equipment is generally simple and affordable
- Requires skill to maintain steady electrode angle and arc length
Stick welding is favored in construction, pipeline maintenance, and heavy equipment repair due to its portability and ability to function well on rusty or dirty metals.

### 2. Gas Metal Arc Welding (GMAW) – MIG Welding
Gas Metal Arc Welding, often known as MIG (Metal Inert Gas) welding, uses a continuous solid wire electrode fed through a welding gun and protected by an inert gas such as argon or a mixture of argon and CO2. This method is known for its ease of use and fast welding speed.
**Key features:**
- Ideal for welding thin to medium-thickness metals
- Produces clean welds with minimal spatter
- Easier for beginners to master compared to stick welding
- Requires gas supply, usually making it less convenient for outdoor use
MIG welding is widespread in automotive manufacturing, light fabrication, and repair industries due to its high productivity and quality finish.

### 3. Gas Tungsten Arc Welding (GTAW) – TIG Welding
Gas Tungsten Arc Welding, or TIG welding, uses a non-consumable tungsten electrode and an inert gas shield (argon or helium). This process provides exceptional control and produces precise, strong, and clean welds.
**Key features:**
- Suitable for welding thin materials and exotic metals (aluminum, magnesium, stainless steel)
- Produces high-quality, aesthetically pleasing welds
- Requires significant skill and practice
- Generally slower than other welding methods
TIG welding is common in aerospace, automotive industries, and high-precision metal fabrication where appearance and strength are critical.

### 4. Flux-Cored Arc Welding (FCAW)
Flux-Cored Arc Welding uses a tubular wire filled with flux. Depending on the type of wire used, FCAW can be self-shielded (no external gas needed) or gas-shielded. This method is capable of providing deep penetration and works well in outdoor conditions.
**Key features:**
- High deposition rate, suitable for thick material welding
- Can be used in windy or outdoor environments without gas shielding (self-shielded FCAW)
- Requires less cleaning compared to stick welding
- Produces more fumes and spatter than MIG welding
FCAW is widely used in construction industries and shipbuilding due to its efficiency and versatility.

### 5. Submerged Arc Welding (SAW)
Submerged Arc Welding involves a continuous wire electrode submerged beneath a blanket of granular flux. The process is largely automatic and provides deep penetration with minimal exposure to fumes and sparks.
**Key features:**
- Used primarily for thick steel parts in heavy industries
- High quality, high productivity welding
- Limited to flat or horizontal positions due to flux coverage necessity
- Not portable - suited for factory or large-scale welding shops
SAW is prevalent in industries such as shipbuilding, pipeline manufacturing, and structural steel fabrication.
