Welding is one of the most crucial processes in metal fabrication, as it forms the backbone of creating strong, durable assemblies. However, selecting the right welding method can be challenging. The two most used techniques are MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding.
At MPJ Fabrications, we are experts in both MIG and TIG welding. Whether your project requires speed, precision, or a specific material, our certified welders ensure exceptional results every time. Let’s explore the key differences and how to determine the right method for your project.
What is MIG Welding?
MIG welding, also known as Gas Metal Arc Welding (GMAW), involves feeding a consumable wire electrode through a welding gun while shielding the weld with an inert gas, such as argon or a mix of argon and carbon dioxide.
Key Features of MIG Welding:
- High Speed: The continuous feed of the wire electrode allows for faster welding, making it ideal for large-scale production.
- Ease of Use: MIG welding is easier to master, which can reduce the risk of errors during the process.
- Versatility: Works well with a range of metals, including mild steel, stainless steel, and aluminium.
When to Use MIG Welding?
MIG welding is the go-to option for projects requiring high efficiency, particularly with thicker materials. It is widely used in industries such as construction, automotive, and manufacturing for tasks like structural components, frames, and assemblies. At MPJ Fabrications, our MIG welding services are tailored for projects demanding strength and speed without compromising quality.
What is TIG Welding?
TIG welding, or Gas Tungsten Arc Welding (GTAW), uses a non-consumable tungsten electrode to create an arc, while a filler rod is manually added as needed. Like MIG welding, the weld is shielded with an inert gas, typically argon.
Key Features of TIG Welding:
- Precision and Control: TIG welding offers superior control, making it ideal for intricate designs and thin materials.
- High-Quality Finish: TIG welding creates a clean and visually appealing weld, often requiring no additional finishing.
- Material Flexibility: TIG welding works exceptionally well with stainless steel, aluminium, and exotic metals like copper.
When to Use TIG Welding?
TIG welding is best suited for projects requiring meticulous attention to detail, such as creating leak-proof seals in piping or decorative metalwork. It is commonly used in industries such as aerospace, food processing, and architectural design. At MPJ Fabrications, our TIG welding expertise ensures high precision and an impeccable finish, especially for stainless steel fabrications.
MIG vs TIG Welding: Side-by-Side Comparison
| Feature | MIG Welding | TIG Welding |
| Speed | High-speed, efficient | Slower, more time-intensive |
| Precision | Moderate | Exceptional |
| Materials | Best for thicker metals | Ideal for thin or exotic metals |
| Finish | Good, may require post-finishing | Clean, high-quality, no finishing needed |
| Skill Requirement | Easier to learn | Requires advanced skill |
