Ready to ShipWelding electrodes come in an incredibly large variety, as they are designed to be used for different applications and with different welding techniques. E7015 electrodes are known for having a relatively low heat and being able to penetrate into the weld pool. They are used with the stick or shielded metal arc welding process.
The following list shows some of the common types of welding E7015 electrodes:
Direct Current Electrode, DCE, (Positive And Negative) - E7015)
Electrodes like E7015 that have a heavy coating on them are best suited for welding metals commonly used in the construction of buildings. The Direct Current Electrode, DCE, can be connected either on the positive or negative terminal depending on the type of coating on the electrode.
Low Hydrogen Electrode - E7015
It has a low concentration of hydrogen in the weld as its name suggests. This leads to a slow release of hydrogen in the welded areas, allowing for safer and slower welds. Ion bombardment of atomic hydrogen causes blistering on welded metals. Such coatings have low hydrogen eletroden and are suitable for joints that are expected to carry heavy loads like steel girders.
Cellulosic Electrodes - E6010
These electrodes are run on direct current power and like all E-series electrodes have a specific number that identifies them as an electrode for a certain welding application. The 6010 family of electrodes, which includes the well-known E6010 are all designed with a core of cellulose which produces a welding arc that is fast penetrating. This allows them to weld on surfaces that may have rust or any other debris.
Metal Cored Electrode - E7015
Metal cored electrode E7015 is a welding rod that has metal powder at the center. This type of electrode provides a steady arc that can weld metals of different thicknesses all at once. Because of its unique construction, the metal core helps to deliver additional welding metal to a joint to enhance strength, thus making it ideal for repair work.
Tungsten Inert Gas Electrode, TIG - E7015
TIG welding uses bare tungsten electrodes to fuse two metals together in a process called welding without fillers. However, the hand arc electric weld E7015 is placed between the two parent metals to enhance weld quality and increase weld strength.
The E7015 coated arc welding electrode has a host of features that make it an all-purpose rod for welding iron and mild steel in manufacturing and construction work.
Medium Coating, 3/32 To 5/32 Inch - E7015
The E7015 has a medium thickness coating which helps to stabilize the welding arc about 3/32 to 5/32 inches. Normally, the weld area will be exposed to environmental factors like air which will impede the weld process. The coating reduces such exposure and protects the weld from contaminants.
Steel And Malleable Casting - E7015
The E7015 is rated for welding steel and malleable cast iron. Malleable iron is actually cast iron that has undergone a special heat treatment called annealing which relieves internal stresses and softens it. This makes it easier to work with and more amenable to changing its shape. Because of its unique properties, E7015 can be used to repair malleable iron breakdowns and support structures in heavy equipment.
AC/DC Power Source - E7015
The E7015 Electrode uses both Alternating Current and Direct Current power sources. AC is used when there is a need to weld very dirty metal surfaces as it helps clean off contaminants. DC is used for welding thin metal and gives better control of welding penetration. This makes the E7015 electrode an all-rounder as it can be used in diverse working conditions.
Improved Bead Appearance - E7015
The E7015 electrode has a unique composition that allows better control of the weld pool. This leads to a better bead formation and minimization of slag. The combination of features enables the E7015 to produce high-quality welds that have good strength and good looks.
All-Position Welding - E7015
The E7015 electrode can be effective in all welding positions. Whether in horizontal or vertical positions, the electrode will maintain a steady arc and good penetration. This ability eliminates the need to have different types of electrodes for overhead or vertical welds.
Welding rods are used in specific ways to ensure that the required welding results are achieved. Here are some suggestions of how E7015 can be utilized optimally.
Weld Preparation - E7015
First, set up the tools and prepare the surface to be welded. The E7015 works better on parent metals with a thickness range of between 5 and 20 mm. Clean the work area by scraping or brushing to remove any contaminants that would impede the weld. It's also important to clamp the work pieces securely so as not to lose alignment as the work proceeds.
Weld Settings - E7015
Adjust the welding machine settings to the right amperage for the E7015 electrode being used. The Electrode Diameter chart gives range settings for different diameter E7015 electrodes. For example, a 3/32 inch diameter electrode should be welded at an amperage range of 35 to 70 amps. Bigger diameter electrodes require higher amperage ranges. Connect the welding leads to the correct terminal for welded alternating current or direct current.
Electrode Striking And Arc Stabilization - E7015
To start, clean the E7015 electrode with a damp cloth to ensure that the working area has been prepared. E7015 is an arc welding rod whose coating is made of iron powder and a mixture of other minerals. This structure helps keep the arc stable and the weld pool steady even when the operator is working on metal with a vertical incline.
Weld Control
The operator should keep the E7015 electrode at a 15-degree angle from the vertical line of the workpiece to maintain good control of the weld pool. After striking the arc, the welder should move the electrode along the joint to deposit molten metal and fuse the workpieces together.
The E7015 electrode is a versatile welding tool that can be used on construction work for steel and iron parts of different thicknesses in all positions. Here are some tips on how to maximize successful welding with E7015:
Use Right Amp Setting
The E7015 needs at its tip the right amperage electrical current setting so that the weld can penetrate properly without causing distortion. Amp settings should be within the range of the electrode diameter being used. Smaller diameter electrodes need lower amper ranges while larger ones can take higher amperages. Consult the manual for guidelines on what combinations to use.
Proper Angle And Travel Speed
The angle of the electrode during the weld should be about 15 degrees off vertical from the work surface. Maintain this angle consistently even if the workpiece is in an overhead or inclined position. Angle and speed both affect bead control and weld formation. Moving too fast would give insufficient filler metal while going too slow would cause excessive pooling and weld build-up.
Maintain Proper Arc Length
Maintaining the correct arc length ensures just the right amount of molten metal is deposited into the weld joint. The E7015 electrode tip should be kept at a distance of around 1/8 inch from the work surface. Crater formation will result from any distance beyond this range. Keeping within this range not only improves penetration but also bead formation quality.
Control Slag Removal
The E7015 coating produces a thin layer of slag that protects the weld area as it cools. However, this slag needs to be removed between passes to allow proper fusion with subsequent welds. Slag left in the welded joint will compromise strength. Waiting until each weld has cooled to a crawl before cleaning allows easier removal without damaging the newly formed weld.
The E7015 welding electrode is a versatile tool for different applications due to the multiple benefits it provides.
Strong, Ductile Welds
The special Iron powder coating allows the E7015 to deposit welds that are homogeneous in texture and consistent in strength. These traits make the joint much more resistant to cracking under heavy impacts or severe temperature changes, typical in mining and excavation work environment.
Good Penetration
The Electrode's unique formulation produces a welding arc with deep penetration that enables the E7015 to bond even thick steel sections. Up to 5 mm in thickness can be welded without pre-heating the metal. This allows repair or fabrication tasks to be completed with a single electrode rather than switching between multiple products for different thicknesses of materials.
Enhanced Slag Removal
The E7015 coat releases easily when cooled after each pass, leaving the weld pool clean and free of impurities. This means no re-welding is necessary to fix contamination issues inside the joint. Slag can be fully cleared instantly between each deposition, speeding the overall welding process while ensuring maximal joint integrity.
Weld In Any Position
Inherently stable due to its properties, the E7015 can complete vertical, overhead, and other challenging joints without losing control of the weld pool. Hard-access areas typical of structural supports and heavy machinery repairs are easily tackled safely. This positions it effectively where many other electrodes would struggle to perform well due to their tendency to run or puddle out.
Economic Choice
With its broad range of applications and long-lasting wear, the E7015 is more affordable than many other options. Designed with efficiency and longevity in mind, the electrode ensures quality results each time for less investment over the long run. It allows savings through reduced maintenance costs on the equipment the welds create.
A. The main difference between E7018 and E7015 is in their coating formulations. E7018 has a thicker, low-hydrogen coating enriched with iron powder to provide a stable arc for smooth, crack-resistant welds. This makes it ideal for heavy structural steelwork. E7015, on the other hand, features a lighter, purely metallic powder-based coat that allows it to penetrate deeper. This enables it to weld both steel and cast iron effectively.
A. The E7015 can be used to weld mild steel and iron structures commonly found in mechanical equipment and components utilized away from covered locations where carting and installation may be difficult such as in excavation, mining, or construction work.
A. While the E7015 coating contains some iron powder that partially qualifies it as a low-hydrogen electrode, its primary function is as a deep-penetration welding rod. For fully low-hydrogen welding, consider electrodes expressly designed for that purpose, such as the E7016 or E7018.
