A: AWS A5.1, ISO 2560, and optionally, EN ISO 2560-A. All files are provided with lot-wise Material Test Certificate (MTC). Third-party certifications from SGS, Bureau Veritas, and DNV-GL can be organized per contract.

Q4: What are the recommended welding parameters?

A: Typical setting for 4.0mm electrode: 190–240A on AC or DC (+ve), 24–28V, with a travel speed of 20–27 cm/min. Pre-weld plate cleaning and optimal positioning (flat/horizontal) are crucial for best results.

Q5: What is the typical shelf life and recommended storage?

A: Shelf life is 24 months in original, dry packaging (

Q6: Which installation standards do Arc welding electrodes AWS E7024 comply with?

A: E7024 welds qualify to ASME IX, EN 287, ISO 9606-1 procedure/operator certifications for steel structures and pipelines.

Q7: How do E7024 compare to E7018 or E6013 in terms of slag removal?

A: E7024 produces low-viscosity, easily removable slag, far superior to E7018 (low-hydrogen, heavier slag) and notably faster than general E6013. This feature minimizes post-weld preparation time—vital for fast-paced production lines.
