Introduction to Welding
Definition and purpose of welding
Welding is a process of joining two or more pieces of metal or thermoplastics by melting, forming a strong bond between them when the material cools down. The purpose of welding in sustainable architecture and design is to create durable connections that enhance structural integrity and longevity. Welding allows architects and designers to fabricate complex designs and shapes using metal components, providing endless possibilities in terms of aesthetics and functionality.
Common types of welding processes
There are several commonly used welding processes in the field of sustainable architecture and design. These include:
-
Shielded Metal Arc Welding (SMAW): Also known as “stick welding,” SMAW involves striking an arc between a flux-coated electrode and the workpiece. The heat generated melts the electrode and the base metal, creating a weld joint.
-
Gas Metal Arc Welding (GMAW): Commonly referred to as “MIG welding,” GMAW uses a wire electrode that is continuously fed through a welding gun. A shielding gas, such as argon, is used to protect the weld pool from atmospheric contamination.
-
Gas Tungsten Arc Welding (GTAW): Also known as “TIG welding,” GTAW uses a non-consumable tungsten electrode to produce the weld. This process requires precise control of both the heat input and the filler metal.
-
Flux-Cored Arc Welding (FCAW): FCAW is similar to GMAW, but it uses a tubular wire electrode with a flux core, which provides the shielding gas and flux for the weld.
Each welding process has its advantages and is suitable for specific applications, depending on factors such as material type, thickness, and desired weld quality.
