7018 welding rods are among the most widely used electrodes in the world of welding. They are known for their versatility and ability to create strong, durable welds. This article explores the key applications of 7018 welding rods, providing essential statistics and insights for welders and professionals alike.
The 7018 welding rod, classified as an E7018 per the American Welding Society (AWS), is a low hydrogen arc welding electrode. It is typically used for carbon steel and low alloy steel applications. The designation "7018" indicates:
Due to these characteristics, 7018 rods are preferred in critical welding applications that require strong and ductile joints.
One of the primary applications of 7018 welding rods is in structural steel fabrication. They are frequently used in building bridges, buildings, and other infrastructures. According to a report by the American Institute of Steel Construction, structural steel use has increased by approximately 29% from 2010 to 2020, emphasizing the importance of reliable welding techniques.
7018 welding rods are often utilized in the repair of heavy machinery, including excavators, cranes, and dump trucks. The rods' ability to withstand high-pressure environments makes them ideal for these applications. Research indicates that approximately 60% of welding activity in manufacturing is related to equipment maintenance and repair.
In the automotive sector, 7018 rods are utilized in frame repair, suspension components, and other structural parts. The growing trend towards electric vehicles is also creating new opportunities for 7018 rods in battery frame construction. According to a report from the International Energy Agency, electric vehicle production is expected to reach 47 million units annually by 2025.
Welders frequently use 7018 rods for pipeline construction and boiler installation. The rods’ low hydrogen characteristics help prevent cracking in high-stress situations, which is crucial in these applications. Data from the American Welding Society indicates that around 20% of all welds in the pipeline industry utilize 7018 rods for their reliability.
7018 welding rods are also essential in the fabrication of pressure vessels. The materials used in these applications require adherence to specific codes and regulations, such as the ASME Boiler and Pressure Vessel Code. Reports from the Pressure Vessel Manufacturers Association show a steady increase in the demand for pressure vessels, with a projected compound annual growth rate (CAGR) of 3.5% from 2021 to 2026.
There are several reasons why 7018 rods are preferred in various applications:
7018 welding rods play a crucial role in numerous industrial applications, ranging from structural steel fabrication to automotive assembly. Their strength, versatility, and reliability make them an essential tool for welders. As industries continue evolving, the demand for effective welding solutions like 7018 rods is expected to remain strong.
