Factory supply 7018 Welding Rods Electrodes

AWS E7018 is basic coated iron powder low potassium hydrogen type electrode. Both AC and DC can be used and can be all-position welding. It can reach  excellent welding performance, good arc stiffness,little spatter, easy slag removal and good weld appearance,high deposition efficiency.Weld metal has excellent plasticity and low temperature toughness

Where E7018 is required, it is recommended to follow the design specifications and use the specified electrode material to avoid quality problems. If it is necessary to replace and use electrodes of other specifications for welding, the welding process parameters should be adjusted according to the different conditions of the specific material to ensure that the welding quality is controllable.

The electrode has excellent welding process performance, good arc stiffness, is not easy to produce magnetic deflection, the weld shape is fine and clean, with less spatter and easy slag removal; the weld metal has excellent and stable low temperature toughness and crack resistance. Both AC and DC can be used for all-position welding. 70 refers to the minimum tensile strength of the weld metal (ksi) 18 refers to the position where the electrode can be used, the type of coating, and the welding current.

It can improve deposition efficiency because of the iron powder in the coating. Its arc is more stable with less spatter.It is easy to remove the residue. It can provide both beautiful welding line shape and good deposited metal mechanical performance.And the current can be AC or DC.It can be used for all position welding.

WELDING POSITIONS:

PA, PB, PC, PD, PE, PF.

X-ray flaw detection: Ⅰ level.

Since the E7018 welding rod is easy to absorb moisture, it is stored in a welding rod drying oven. The electrodes stored in the air can be re-baked at 350-400°C for 1h-2h. In order to restore the performance of its drug skin. Mild steel can be welded with unbaked E7018 electrodes, but the weld strength may not be high enough.
