Quick Answer

Compare E6013 and E6010 costs per accepted weld only when the welding procedure permits both for the same joint and pass. Use the same weld size, inspection criteria and site conditions. Add delivered electrodes, labor, cleaning, inspection and rework, then divide total trial cost by accepted output. If only one class is approved, compare named products within that class instead.

Key Takeaways

• A shared E60 strength class does not authorize E6013-to-E6010 substitution in a WPS.
• Delivered price per kilogram excludes time, rejection and repair costs.
• Product-sheet deposition efficiency does not establish local accepted-weld cost.

Are E6013 and E6010 Comparable on This Job?

Both are carbon-steel covered-electrode classifications within AWS A5.1/A5.1M, but their operating families and applications differ. E6013 may suit approved general fabrication; E6010 often serves an approved penetrating pipe root.

A drawing or welding procedure specification (WPS) can prescribe a class or named product. If only one class is approved, seek competing offers within it rather than treating the other class as a price substitute.

Where both are eligible, control base metal, joint preparation, position, polarity, pass sequence, deposited weld size and acceptance method.

What Belongs in Cost per Accepted Weld?

Normalize delivered consumable cost by net electrode kilograms and the same freight basis. Track rods issued, unused usable rods, stubs and damaged covering without treating purchased weight as deposited weld metal.

Add arc-on time, rod changes, cleaning, fit-up and normal labor. Record inspections, rejects, grinding and repair. Keep one-time qualification expense separate from repeat-production expense.

Calculation: cost per accepted weld = (electrodes consumed + labor + inspection + rework) ÷ accepted identical welds. For different lengths, instead use the same accepted weld length and stated inspection basis.

For example, ESAB Weld 6013 publishes product-specific deposition data; it cannot be transferred to a rival’s E6013 or an E6010 product.

How Can Buyers Run a Fair Comparison?

Use approved welders, representative joints, identical acceptance criteria and enough repetitions to expose normal variation. Record actual named products, diameters, machine settings, polarity and lot identification.

Time the entire weld cycle and inspect every trial joint. Do not use one attractive bead as a productivity percentage. Document unusual stoppages before drawing a purchase conclusion.

If one class belongs only on a root pass, calculate its root-pass costs separately from later-pass consumables.

What Should Suppliers Quote for a Cost Trial?

RFQ checklist:

1. Approved class, pass and WPS: exclude noncompliant price comparisons.
2. Trade name, diameter and length: trial the exact saleable product.
3. Polarity, amperage and positions: verify site-machine compatibility.
4. Net inner-pack weight and carton count: normalize unit cost.
5. Delivered price and included services: capture freight, samples and testing on the same basis.
6. Datasheet, lot marking and damaged-covering remedy: protect repeatability and usable yield.

Keep trial records with the approved product and lot for reorders.

Buyer FAQ

Can a cheap E6013 replace an E6010 root rod?

Not without review and approval by the responsible welding engineer and applicable WPS.

Is price per kilogram enough?

No. Use complete costs divided by accepted, comparable weld output.

Should inspection cost be counted twice after repair?

No. Record each actual material, labor and inspection expense once in the trial ledger.
