4. Opsætning og klargøring
Proper setup is crucial for achieving optimal welding results and ensuring safety.
- Forberedelse af arbejdsområde: Clear the welding area of any flammable materials. Ensure good ventilation.
- Strømkilde: Connect your welding machine to a suitable power source according to its specifications.
- Valg af elektrode: Ensure you are using the correct E7018 electrode size (1/8" for this product) and type for your application.
- Electrode Holder and Ground Clamp: Tilslut elektrodeholderen og jordforbindelsenamp securely to your welding machine.
- Forberedelse af emne: Rengør emnet grundigt for at fjerne rust, maling, olie eller andre forurenende stoffer, der kan påvirke svejsekvaliteten.
- Preheating (if necessary): For certain high-strength steels or thick sections, preheating may be required to prevent cracking. Consult welding codes or material specifications.
5. Betjeningsvejledning
E7018 electrodes are low-hydrogen electrodes, requiring specific handling and welding techniques for best performance.
- Nuværende type: E7018 electrodes can be used with both AC (Alternating Current) and DC (Direct Current) reverse polarity (DCEP/DC+). DC reverse polarity is generally preferred for better arc stability and penetration.
- Amperage Settings: Refer to the electrode manufacturer's recommended amperage range. For 1/8" (3.2mm) E7018 electrodes, a typical range is 90-150 amps, but this can vary based on joint type, position, and material thickness.
- Buelængde: Maintain a short arc length. This helps to maintain the shielding gas and prevent porosity.
- Rejsehastighed: Maintain a consistent travel speed to ensure proper bead width and penetration. Too fast can lead to shallow penetration; too slow can lead to excessive heat input and distortion.
- Elektrodevinkel: Hold the electrode at a slight drag angle (10-30 degrees from vertical in the direction of travel).
- Weaving Technique: A slight weave can be used to control bead width and penetration, but avoid excessive weaving which can lead to slag inclusions.
- Fjernelse af slagge: After each pass, allow the weld to cool slightly, then chip off the slag. E7018 slag is typically easy to remove.
6. Vedligeholdelse og opbevaring
Proper storage and handling of E7018 electrodes are critical to maintain their low-hydrogen properties and prevent moisture absorption.
- Opbevaring: Store electrodes in a dry, sealed container or a heated electrode oven (rod oven) to prevent moisture pickup. Moisture can lead to hydrogen embrittlement and porosity in welds.
- Rebaking: If electrodes have been exposed to moisture, they may need to be rebaked according to manufacturer specifications to restore their low-hydrogen properties.
- Håndtering: Handle electrodes carefully to avoid damaging the flux coating. A damaged coating can lead to unstable arcs and poor weld quality.
- Udløb: While electrodes don't typically expire, their performance can degrade if not stored correctly over long periods.
7. Fejlfinding
Common issues encountered when welding with E7018 electrodes and their potential solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Difficulty striking/maintaining arc | Lav amperage, damp electrodes, poor ground connection, improper technique, brittle flux. | Øge amperage, rebake electrodes, check ground clamp, practice striking technique, inspect electrode for flux damage. |
| Overdreven sprøjt | For højt amperage, long arc length, incorrect polarity. | Reducere amperage, shorten arc length, ensure DCEP/DC+ polarity. |
| Porøsitet (huller i svejsningen) | Damp electrodes, contaminated base metal, too long arc, insufficient shielding. | Rebake electrodes, clean base metal, shorten arc, ensure proper ventilation (avoid drafts). |
| Slag inclusions | Improper cleaning between passes, excessive weaving, incorrect electrode angle. | Thoroughly clean slag, reduce weave, adjust electrode angle. |
| Underskæring | For højt amperage, too fast travel speed, incorrect electrode angle. | Reducere amperage, sænk kørselshastigheden, juster elektrodevinklen. |
