Understanding Welding Basics
What is Welding?
At its core, welding is a fabrication method that unites materials, mainly metals or thermoplastics, by generating coalescence. In order to create a robust junction after cooling, this is usually accomplished by melting the workpieces and adding a filler material. Proper welding techniques and equipment are crucial for ensuring the quality and safety of the welds, making it a highly skilled and critical trade in modern engineering and production.
Different Types of Welding Techniques
- MIG Welding: Metal Inert Gas (MIG) welding, also known as Gas Metal Arc Welding (GMAW), uses a wire feeding gun that feeds wire at an adjustable speed and flows an argon-based shielding gas over the weld puddle to protect it from atmospheric contamination.
- TIG Welding: Tungsten Inert Gas (TIG) welding, or Gas Tungsten Arc Welding (GTAW), uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas such as argon or helium.
- Stick Welding: Stick welding, often referred to as shielded metal arc welding (SMAW), applies a flux-coated electrode to lay the weld by passing an electric current through it and creating an arc between it and the metals that need to be united.
- Flux-Cored Arc Welding: Similar to MIG welding, but has the added versatility of being able to be used both with and without shielding gas. It employs a unique tubular wire that has been loaded with flux.
- Spot Welding: Spot welding is a technique used to join metal sheets by applying pressure and heat at specific points, creating welds. It’s commonly used in automotive and manufacturing industries.
- laser welding: Laser welding is a precise technique that uses a focused laser beam to join materials. It’s ideal for thin metals and high-speed applications, offering strong, clean welds with minimal distortion.
