This page covers the electrode line only. Our brazing filler metals sit under a separate label and a separate website, because the two are bought by different people for different reasons: an electrode buyer is choosing a coating and a current, while a brazing buyer is choosing a silver content and a melting range. Keeping the two catalogues apart is what lets each one say something specific.
Six AWS families, one coating line
We would rather run six families properly than list every grade on the market. The range is organised by AWS specification, because that is how buyers and welding engineers actually specify:
Aluminium & aluminum alloy welding electrodes, SMAW, TIG, MIG. AWS A5.3 & AWS A5.10 grades E1100, E4043, ER4043, ER5356
Stainless steel electrodes, AWS A5.4 — E308L-16, E309L-16, E316L-16, E347-16
Cast iron electrodes, AWS A5.15 — ENi-CI, ENiFe-CI
Hardfacing and surfacing electrodes, AWS A5.13
Cellulosic pipe electrodes, AWS A5.1 — E6010, E8010-G
Nickel & Nickel-Alloy Electrodes, AWS A5.11, ENi‑1, ENiCrFe‑3, ENiCu‑7, ENiCrMo‑3(Ni625), ENiCrMo‑4(C276)
Grades outside this list are quoted case by case. If a grade is outside what our line can coat consistently, we say so before quoting rather than after the container arrives.
From core wire to sealed carton
An electrode is two products in one: a metal core that carries the current, and a coating that decides how the arc behaves. Neither half can be bought in and assembled; the grade only exists once the coating is on the wire.
The core is a low-carbon steel wire, copper-coated so it conducts current along its whole length and does not rust in storage. Core diameter sets the current range the finished electrode can handle, which is why a 2.5 mm and a 4.0 mm of the same grade are not interchangeable on the same job.
The coating is where the grade is actually made. A rutile grade, a low-hydrogen grade and a cellulosic grade differ mainly in what goes into the mix: rutile sand for arc stability and a smooth bead, calcium carbonate and cellulose for gas generation, ferro-alloys for alloying and deoxidation, and a silicate binder that holds the powder together and gives the pressed coating enough green strength to survive handling before baking.
The mix is pressed around the core in a continuous extrusion head. Coating thickness and concentricity are fixed at this point. An eccentric coating pulls the arc to one side, fuses one wall of the joint harder than the other and leaves a wandering bead; a thin spot burns through, and the core melts before the coating can shield it. This is the single most common cause of a batch that welds badly while every chemistry report still looks correct.
Pressed electrodes go through low-temperature drying to drive off free water, then a high-temperature bake that removes chemically bound moisture. Low-hydrogen grades live or die at this step: residual moisture becomes diffusible hydrogen in the weld, and hydrogen is what cracks high-strength steel and thick sections. Baked electrodes are cooled, printed and packed into moisture-barrier cartons, with the batch number recorded before the carton is sealed.
What we check before a carton is sealed
Each batch is checked on the things that fail in service, not only on the things that are easy to measure:
Core wire diameter and the condition of the copper layer
Coating thickness, concentricity and adhesion
Moisture content after baking, and diffusible hydrogen on low-hydrogen grades
Weld test: arc starting and restriking, spatter level, slag detachability, bead profile, visible porosity
Retained sample and batch number held against the shipment record
What a buyer can check before ordering
We would rather send you five kilograms to burn than a PDF to read. A trial quantity is the fastest way for a welding engineer to judge an electrode, and it is cheaper for both sides than a container that fails a procedure test.
Alongside the sample we can provide the batch test record, the mill certificate for the core wire, packing artwork for approval, and, where a project requires it, a third-party test report. Documents follow the shipment, not a separate request afterwards.
Packing, private label and paperwork
Electrodes are supplied in the diameters and pack weights listed on each product page, in cartons, inner boxes and pallets sized for container loading. Low-hydrogen grades can be packed with a moisture barrier for long sea transit.
Private label is available: your carton artwork, your grade naming, your language. Every carton carries grade, size, current range and baking instructions, because those are the four things a welder reads before opening the box, and getting them wrong is how a good batch gets rejected on site.
Support that continues after the shipment
Grade selection is the part buyers ask about most, and it is usually a question about the job rather than the product: base metal, thickness, welding position, available current, and any code the work has to satisfy. We answer those questions directly, and where a customer needs a procedure reviewed, we will go through the WPS and PQR with them.
If a batch is disputed, the batch number leads to the retained sample, the sample goes back through a weld test, and the finding is written down and sent to the customer. A complaint answered with a test record is worth more than one answered with an apology.
How to get a quote
Send the grade list, the annual volume, the destination port and the packing you need, and tell us the trade term you work on. We reply with grade availability, packing options, lead time and a trial quantity. Where a grade needs to be developed for a specific base metal or code, say so at the start — it changes the lead time, and it is better to know that now than at the loading dock.
If a grade is outside what our line can coat consistently, we say so before quoting. That is cheaper for you than a container that fails a weld test.
