Submerged Arc Welding Flux: Selecting the Appropriate Type and Application

Submerged Arc Welding Flux It is a critical auxiliary material used in the welding process, providing the necessary chemical and physical conditions to ensure welding quality and efficiency. When selecting submerged-arc welding flux, it is essential to make a choice based on specific application requirements and operating conditions. This article will discuss the types of submerged-arc welding flux, their applications, and key considerations for selection.
 

I. Types of Submerged Arc Welding Flux

Submerged Arc Welding Flux Depending on the specific application scenario and purpose, they can be categorized into various types.

Acid flux: Acid flux is primarily used for welding low-carbon steels and low-alloy steels, characterized by its ability to produce very small pore sizes and excellent liquid surface tension.

Alkaline Flux: Alkaline flux is primarily used for welding stainless steel, copper, aluminum, and other materials. Its key characteristics are a highly stable arc and excellent penetration.

Active flux: Active flux is primarily used for welding galvanized materials, Monel, and similar alloys. Its key characteristics are its ability to produce very small pore sizes and its excellent liquid surface tension.

Low-dust flux: Low-dust flux is primarily used for welding materials such as galvanized steel and Monel alloy. It is characterized by providing extremely small pore sizes and excellent liquid surface tension, while also reducing the amount of flux required.

II. Applications of Submerged Arc Welding Flux

The primary purpose of submerged-arc welding flux is to provide the necessary chemical and physical conditions for the welding process, thereby ensuring weld quality and efficiency. Specifically, Submerged Arc Welding Flux Its functions include the following aspects.
