Stick Electrodes

Stick Electrodes Explained

Stick welding is the classic arc process. It is formally called SMAW (Shielded Metal Arc Welding), and the consumables are often referred to as manual welding rods. The process has served construction, pipeline and industrial work for more than 100 years.What sets a stick electrode apart is its construction: a metal core wire wrapped in a flux coating. Once the arc is struck, the coating burns off and forms a gas shield over the molten pool, keeping oxygen and nitrogen away from the weld metal.Stanvac International manufactures stick welding rods for demanding work, from structural steel buildings to pressure vessels, and ships them to customers worldwide. Our rods are made for consistent quality, strong penetration and welds that hold up over time.

Reasons Stick Welding Is Still Widely Used:

• Simple and mobile – no gas cylinders or complicated equipment needed
• Handles tough conditions – wind, rain and open-air jobs are not a problem
• Strong penetration – deep, sound welds in heavy sections
• Wide choice – rods exist for steel, stainless, hardfacing and specialist uses
• Economical – project costs stay below those of many newer processes
• Tolerant – newer welders can reach acceptable results with some practice

Stick Electrode and Welding Rod Types

Carbon Steel Stick Electrodes (6010, 6011, 7018, 8018)

Carbon steel rods are the most widely used group. They suit mild and low-carbon steels in construction, shipbuilding and heavy fabrication.

E6010 Electrodes – Deep Penetration

• A top choice for root passes and heavy sections
• Well regarded for pipeline welding
• Copes with rusty or contaminated surfaces
• Produces deep, strong welds
• Demands an experienced welder

E6011 Electrodes – General Purpose

• Can be used in every welding position
• Penetrates well without going too deep
• Common in structural steel fabrication
• Runs on either AC or DC power sources
• More approachable for less experienced welders

E7018 Electrodes – The Most Popular Choice (Low Hydrogen

)• The very low hydrogen coating helps prevent cracking

• DC power is the recommended supply

E8018 Electrodes – Added Strength

• Higher tensile strength for demanding jobs

Stainless Stick Electrodes (E308, E316, E347)

Where corrosion resistance matters, stainless stick electrodes are the correct choice. They join stainless steel and protect the weld against rust and chemical attack over the long term.

E308 Stainless Stick Electrode

• Everyday stainless steel welding
• Matches SS 304 and comparable grades
• Offers good resistance to corrosion
• Found in food processing and kitchen equipment
• An economical option

E316 Stainless Stick Electrode

• Molybdenum content gives superior corrosion resistance
• Matches SS 316 and highly alloyed stainless steels
• Well suited to chemical plants and coastal sites
• Stands up better to chloride attack
• High quality with extended service life

E347 Stainless Stick Electrode

• Niobium addition for high-temperature service
• Used in power generation and heat exchangers
• Keeps its strength at elevated temperatures
• Applied in aerospace-grade work
• Top-level durability and strength

Specialty and Hard Facing Electrodes

Outside the standard carbon steel and stainless ranges, specialty electrodes handle particular problems:Hard Facing Electrodes – Wear ProtectionApplied to bucket teeth, drill bits and other parts that suffer heavy abrasion, they build a very hard surface that resists wear.Cast Iron Electrodes – Repair WorkTheir special composition allows cast iron to be welded without cracking, which is vital when fixing broken machinery and engine blocks.Nickel Alloy Electrodes – Severe CorrosionChosen for deep-sea service and chemical processing, where ordinary stainless steel falls short.Iron Powder Electrodes – Higher ProductivityIron powder in the coating permits faster travel speeds and greater deposition rates.

Low Alloy Electrodes

Built for jobs needing high strength, heat resistance and superior mechanical performance, these electrodes serve pressure vessels, pipelines, boilers and structural parts working in severe conditions. A low alloy electrode gives outstanding toughness and resistance to cracking.

Nickel Alloy Electrodes

These electrodes weld nickel alloys, which are chosen for aircraft components, engine parts and aerospace equipment because of their strength, corrosion resistance and heat resistance. They are also used in chemical processing plants, on reactors, pipelines and equipment exposed to corrosive chemicals and acids.

Cast Iron Electrodes

Stanvac offers advanced cast iron electrodes for repairing cracked or worn parts, with attention to machinability, crack resistance and compatibility. Hardfacing electrodes shield surfaces from wear, impact and abrasion, which makes them a good match for mining, crushers and heavy-duty equipment.

Copper Alloys Electrode

Copper alloy electrodes are applied in several arc welding processes to join and surface copper and its alloys, with particular types for particular jobs. They combine strong corrosion resistance, good weld strength, machinability and ductility, and perform dependably in harsh industrial settings.

Hardfacing Electrode

A hardfacing electrode rebuilds or upgrades worn surfaces by laying down a tough, wear-resistant layer. With excellent durability, high abrasion resistance and strong adhesion, it suits heavy machinery, industrial equipment and high-impact applications.

Selecting the Correct Stick Welding Rod for Your Job

The right electrode is essential to a successful weld. This short guide will help:

Step 1: Determine the Base Metal

• Mild steel, stainless steel, cast iron or something different?
• The answer sets the electrode family (6xxx, 7xxx, E308, etc.)

Step 2: Review the Strength Needed

• Is very high strength required (E8018)?
• Or will standard strength do (E7018)?

Step 3: Look at the Joint

• Root pass on heavy material → E6010 or E6011
• Cap pass where looks count → E7018
• Work in all positions → E7018 or E6011

Step 4: Assess the Service Environment

• Exposure to rust or chemicals? → Stainless electrode
• Outdoor or damp conditions? → Low hydrogen (7018)
• Elevated temperature? → E347 or a special alloy

Step 5: Consider the Welder's Experience

• New to welding? → E6011 or E7018 are tolerant
• Highly skilled? → E6010 rewards professionals with better results

If you are unsure, talk to your electrode supplier. Stanvac International can suggest a suitable electrode for your particular project.
