Key Features of 7018 welding rods:
Low-Hydrogen Electrode: 7018 rods are designed to minimize the hydrogen content in the weld, reducing the risk of cracking.
Applications: 7018 welding rods are commonly used in construction, shipbuilding, pipelines, structural steelwork, and heavy equipment repair. They excel in applications where strength and durability are critical, such as:
Whether you’re working on high-strength structural welds or simple repairs, 7018 welding rods provide the performance, durability, and versatility to get the job done right.
The three primary categories of electrodes—cellulose, rutile, and basic (low-hydrogen)—obtain their name from the coating type. Electrode coatings help optimise performance for various applications by influencing how quickly the slag freezes; penetration (deep, medium, or mild); and deposition rate. The coating also contributes to good arc initiation, easy restrikes, puddle control, and a stable arc with minimal spatter.
Basic. Basic electrodes offer an arc with medium penetration and excellent mechanical properties. The coating is low-hydrogen iron powder, TiO2, CaCO3, and CaF2 (calcium fluoride). The coating is of medium thickness, and the addition of iron powder increases deposition. It freezes relatively fast to enable flat, horizontal, vertical-up, and overhead welding.
