A Comprehensive Overview of China 7018 AC Welding Rod Suppliers

Welding is a crucial process in various industries, facilitating the assembly and fabrication of metal components. Among the numerous types of welding rods available, the 7018 series is particularly popular due to its versatility and strength, especially in AC applications. This article delves into the characteristics of 7018 AC welding rods, their applications, and an overview of suppliers in China.

Understanding 7018 AC Welding Rods

The 7018 welding rod is classified under the E7018 category, which signifies that it is an electrodes designed for arc welding using covered electrodes. The number 7018 indicates that it can weld materials with a yield strength of 70,000 psi (pounds per square inch) and a tensile strength of about 80,000 psi, making it suitable for heavy-duty applications. The '1' indicates that the rod can be used in all positions, while '8' signifies the low hydrogen content of the electrode, which is vital in preventing weld cracking and ensuring a clean finish.

In AC applications, 7018 rods are particularly advantageous as they can be used with alternating current power sources, allowing for greater versatility in welding practices. The use of these rods helps achieve a smoother and more stable arc, which is essential, especially for thicker materials.
