Welding Electrodes – Learn About Its Types And Uses
A metal wire coated with a similar composition to the metal being joined is defined as a welding electrode. Several factors to consider before choosing All Kinds Of Welding Equipment And Accessories for any project.
The arc welding electrode/ SMAW is consumable as they become part of the weld fusion. It refers to the TIG electrodes as non-consumable as they do not become part of weld on melting. The MIG welding electrode is a regularly fed wire named as MIG wire.
The welding electrode selection largely depends upon weld strength, easy to clean up. better bead quality, and minimal spatter.
WELDING ELECTRODES need to be stored in a moisture-free surrounding and remove carefully from the package to avoid any damage following directions carefully.
Why are Welding Electrodes Covered?
Once the molten metal is exposed to the environment, it absorbs oxygen and nitrogen which affect adversely and become brittle. A slag blanket would have to cover molten/ solidifying weld metal to shield from the atmosphere and electrode coating provides us with this shield.
The WELDING ELECTRODES coating composition determines their utility and therefore the composition of the deposited weld metal and specification.
They base the formulation of welding electrode coatings on the established principle of metallurgy, physics, and chemistry.
The coating is there to protect from damage, arc stabilization, improves the welding in the following ways.
- Minimum spatter in the welding’s vicinity zone
- A smooth surface of weld metal and edges even
- A stable and smooth welding arc
- A tough and strong coating
- Easy slag removal
- Better deposition rate
- Penetration control in welding
We may classify the arc welding electrode into thin coated/bare and heavily coated/shielded arc electrodes. The covered sort of electrode is a kind of popular style of filler material in the arc welding process.
The electrode covering’s composition determines the utility of the electrode, and specification deposited material decides the electrode. The category of electrode used largely depends upon the special properties within the weld deposit required.
These properties include corrosion resistance, high enduringness, ductility, base metal type to be welded, the position of the weld as horizontal, vertical, overhead, and kind of current and polarity.
The welding industry has adopted the welding rod classification number series decided by the American Welding Society (AWS).
The identification system of the electrode for steel arc welding is adopted as follows.
- E- This E indicates electrode for arc welding
- The 1st two or three digits – It indicates the tensile strength in thousands of pounds /square inch of deposited material once tried to pull apart.
- The 3rd or 4th digit – It indicates the position of the weld. If 0 it shows no classification used, 1 is for every position, 2 for flat and horizontal, 3 is for flat position only.
- The 4th digit – It indicates the type of coating and the type of electric power supply, AC/DC, straight or reverse polarity.
- The number E6010 – Now it indicates an arc welding rod with a stress tensile strength of 60,000psi, can be used in all positions, and direct current with terse polarity.
