Understanding arc welding: What is it? Advantages and applications

When discussing common welding methods, arc welding emerges as a favored and widespread technique. So, what exactly is manual arc welding? This article by Thetech will provide you with valuable information.

What is arc welding?

Arc welding is a welding method carried out by using energy from light sources or lasers to melt and join metal materials. This process typically involves gases like CO2 or employs laser types such as Nd:YAG, fiber lasers to generate intense light. When this light interacts with the material, it generates high temperatures sufficient to melt and bond the metal materials together.

The arc welding method is favored for its capability to concentrate high energy into a specific point, providing precise and minimally disruptive welding to surrounding areas. It can be used on thin or pliable materials and can even be utilized in air or non-protective air environments.

Arc welding finds extensive application in manufacturing industries, engineering, medicine, and scientific research due to its ability to create accurate and robust connections between metal materials.
