With strong performance characteristics and broad applicability, ER70S-6 is expected to maintain its position as the most widely used solid MIG welding wire globally.

When sourcing ER70S-6 MIG welding wire, several common pitfalls can compromise both quality and intellectual property (IP) protection—especially when dealing with international suppliers. Using H2 (a controlled environment with low hydrogen potential) is critical in certain welding applications to prevent hydrogen-induced cracking (HIC), making material integrity and traceability even more vital. Below are the key pitfalls to avoid:

---

🔹 1. Poor Quality Control from Unverified Suppliers

Pitfall: Sourcing from low-cost suppliers without proper quality certifications or traceability.

Risks:
– Inconsistent chemical composition (e.g., Mn, Si levels affecting weld strength and ductility).
– Excessive moisture or surface contamination, increasing hydrogen pickup—critical in H2 environments.
– Substandard packaging leading to oxidation or moisture absorption.

Mitigation:
– Require certified mill test reports (MTRs) per AWS A5.18 or ISO 14341.
– Audit suppliers and request third-party inspection reports (e.g., SGS, BV).
– Ensure sealed, moisture-proof packaging (especially for H2 service).

---

🔹 2. Lack of Traceability & Material Certification (IP and Compliance)

Pitfall: Inadequate documentation or falsified certs, risking IP exposure and non-compliance.

Risks:
– Use of counterfeit or mislabeled materials.
– Inability to trace material origin—problematic for quality audits or failure investigations.
– Potential IP leakage if proprietary welding procedures are exposed during sourcing.

Mitigation:
– Enforce full material traceability (heat number, batch number).
– Use NDAs with suppliers to protect welding parameters and application details.
– Specify ASME BPVC, API 1104, or NACE MR0175 compliance for H2 service.

---

🔹 3. Hydrogen Contamination Risk (Critical for H2 Environments)

Pitfall: Using wire not stored or handled properly, leading to hydrogen pickup.

Risks:
– Hydrogen-induced cracking (HIC), especially in high-strength or thick-section welds.
– Compromised weld integrity in hydrogen service or sour environments.

Mitigation:
– Source low-hydrogen certified wire (typically <5 ml/100g diffusible H₂).
– Ensure baked and hermetically sealed packaging.
– Store wire in dry, climate-controlled environments post-delivery.
– Prefer copper-coated ER70S-6 with low moisture absorption.

---

🔹 4. Inadequate Supplier Vetting & Geopolitical IP Risks

Pitfall: Sourcing from regions with weak IP enforcement, risking reverse engineering or data theft.

Risks:
– Copying of proprietary welding procedures or alloy modifications.
– Loss of competitive advantage in specialized applications (e.g., hydrogen pipelines, fuel cells).

Mitigation:
– Work with trusted, IP-conscious suppliers (e.g., in North America, EU, Japan).
– Avoid disclosing full technical specs; use performance-based specs where possible.
– Include IP clauses in procurement contracts.

---

🔹 5. Non-Compliance with Industry Standards for H2 Service

Pitfall: Assuming all ER70S-6 wire is suitable for hydrogen environments.

Risks:
– Standard ER70S-6 may meet structural specs but fail under H2 embrittlement.
– Lack of testing for sulfide stress cracking (SSC) or H₂ permeation resistance.

Mitigation:
– Specify NACE-compliant or H2-ready variants of ER70S-6.
– Require HIC testing (per NACE TM0284) for sour service applications.
– Use supplemental requirements in purchase orders (e.g., “for hydrogen service, low-diffusible hydrogen”).

2. Shielding Gas Consideration: Use of H₂ (Hydrogen)

⚠️ Critical Warning: H₂ is NOT recommended for use with ER70S-6 welding wire.

Why H₂ Should Not Be Used:

• Hydrogen Embrittlement Risk: ER70S-6 is not formulated for hydrogen-containing atmospheres. Use of H₂ increases the risk of hydrogen-induced cracking (HIC), especially in steels with higher carbon content or in restrained joints.
• AWS Standards: AWS A5.18 does not qualify or recommend ER70S-6 for use with hydrogen-containing shielding gases.
• Typical Shielding Gases for ER70S-6:
• Pure CO₂
• 75% Ar / 25% CO₂ (most common)
• 90% Ar / 10% CO₂
• H₂ Applications: Hydrogen is sometimes used in stainless steel welding (e.g., with tri-mix gases like Ar/He/H₂) to increase heat input and improve bead profile — but not for carbon steel wires like ER70S-6.

Recommendation:

❌ Do not use H₂ as a shielding gas with ER70S-6.
✅ Use CO₂ or Ar/CO₂ blends as specified by AWS and manufacturer guidelines.
