Our Cellulosic Welding Electrodes Range
The full range of cellulosic welding electrodes from Ador Welding — supplied with batch certificates, OEM authorisation documentation, and rate-contract pricing for bulk and recurring requirements.
E6010 / Tenacito 60
Cellulosic stick electrode — fast-freezing, high-penetration, deep-fusion root-pass for low-carbon steel piping. Ideal for vertical-down welding of API 5L Grade B pipes, all-position welding.
E7010-A1 / Tenacito 70
Cellulosic-iron-powder electrode — root-pass and fill-pass on ASTM A106 Grade B and C, A335 P1 chrome-moly steels for oil & gas distribution. Higher tensile than E6010.
E7010-G / Vertirod
All-position cellulosic for high-carbon-steel pressure piping in refineries. Specified for stove/oven piping and refinery process columns.
E8010-G / Tenacito 80
Cellulosic for heavier-wall pipes (XL grade) and long-distance cross-country pipelines. Excellent vertical-down characteristics.
E8010-P1 / Cellucord
Cellulosic-iron-power for X65 to X70 line pipe — common in CNG distribution and gas transmission lines.
E9010-G
Higher-strength cellulosic for sour-gas service and X80 line pipe applications. Lower availability — supply on advance order.
E11018-G low-hydrogen complement
Used for cap pass after cellulosic root in critical applications — combines cellulosic root advantages with low-hydrogen weld toughness.

Frequently Asked Questions
What's the difference between E6010, E7010 and E8010 cellulosic electrodes?
The numerical suffixes correspond to minimum tensile strength: E6010 is 60 ksi (414 MPa), E7010 is 70 ksi (483 MPa), and E8010 is 80 ksi (552 MPa). E6010 is used for general low-carbon piping (API 5L Grade B). E7010-A1 adds carbon-molybdenum for higher-temperature service. E8010-G and E8010-P1 are used for X65 / X70 line pipe and heavier-wall fittings. The choice depends on the parent material grade specified in your construction/welding spec.
Why use cellulosic instead of low-hydrogen for pipeline root-pass?
Cellulosic electrodes generate hydrogen-rich shielding that produces a forceful, deep-penetrating arc — ideal for fast-freezing root-pass welds in vertical-down position. This is why almost all cross-country pipeline construction uses cellulosic for the root and hot pass. Low-hydrogen (E7018, E8018, E11018) is then used for fill and cap to keep weld-metal hydrogen low and improve toughness. Combining the two captures the best of both.
Are Ador Tenacito and Cellucord electrodes API 1104 qualified?
Yes. Ador's Tenacito and Cellucord ranges are widely used and qualified for API 1104 welding procedure qualifications across PSU and private pipeline projects in India. We supply with batch certificates that support PQR documentation. Most refinery and gas-transmission contractors specify Ador Tenacito by name in their approved-vendor lists.
Do you supply for oil & gas pipelines across India?
Yes. We're a pan-India distributor for Ador cellulosic electrodes, with supply across HPCL Visakhapatnam, BPCL Kakinada, ONGC, IOCL refinery and pipeline divisions, GAIL gas networks, Reliance Jamnagar, MRPL Mangalore. Bulk dispatch from our Secunderabad warehouse — typical order quantities are 200-1000 kg per project, packed in moisture-resistant 5 kg / 25 kg cartons.
How do I store and handle cellulosic electrodes?
Cellulosic electrodes need a moisture content of 4-6% in the coating to function correctly (this is opposite to low-hydrogen electrodes, which need to be dry). Store in original sealed cartons in a cool, dry warehouse. Do not over-bake — that destroys the cellulose. Once a carton is opened, use within 4-8 hours. Re-seal partial cartons in moisture-barrier bags. Ador's packaging includes a moisture-control wrapper that maintains coating moisture during transit.
Can you provide PSU and GeM tender documentation?
Yes. As a GeM-registered (Government e-Marketplace) supplier, we provide the full pre-bid pack: OEM authorisation letter from Ador, type-test certificates per AWS A5.1, API 1104 qualification support, BIS/IS compliance reports, and OISD-RP-189 conformance for refinery applications. PSU tenders frequently specify cellulosic electrodes for pipeline work — we routinely respond to HPCL, BPCL, IOCL, ONGC, GAIL inquiries with same-day documentation.
What pack sizes and lead times do you offer?
Standard pack: 5 kg cartons (moisture-controlled), boxed in 25 kg or 50 kg shipping units. Bulk dispatch direct from Secunderabad warehouse — same-day for stocked Tenacito 60, 70, 80 grades; 5-7 days for E9010-G and specialist cellulosic-low-hydrogen combinations. Minimum order: 25 kg for stocked grades, 200 kg for made-to-order specials.
