7018 welding rods, also known as low-hydrogen electrdoes, are designed to minimise hydorgen in the weld which should reduce the risk of cracking. 7018 rods produce a clean weld with a smooth finish, creating minimal slag. They're suitable for many projects due to their versatility in terms of positioning, while their high tensile strength (around 70,000 psi) means they can weld carbon steel and low alloy steel with ease.
As such, 7018 weld rods are most often used in construction, shipbuilding, pipelines, structural steelwork and heavy equipment repair. They excel in applications where strength and durability are critical, making them suitable for such industries. Where the integrity of the weld is crucial, 7018 welding rods excel, not least in large-scale infrastructure projects. That said, they're useful for hobbyists with tough welding projects coming up, like fixing tractors and other heavy machinery at home.
For best results using Engweld's 7018 low hydrogen welding rods, using DC+ current. The rods should always be stored in a dry environment and kept in a rod oven to provent moisture build up. During the welding process, 7018 rods are ideal for drag or "dragging" techniques, where the rod is moved smoothly across the joint itself.
The great thing about 7018 rods is that whether you’re working on high-strength structural welds or simple repairs, 7they provide the performance, durability and versatility to get the job done well every time.
