Welding Electrode and Filler wire Selection Charts

How to make the selection of welding electrodes or filler wire?

Looking for a Welding Electrode and Filler Wire Selection Chart? Download our comprehensive PDF chart to simplify your electrode and filler wire selection process for any material.

Discover the key factors to consider, such as base metal compatibility, welding position, and desired mechanical properties when choosing the right filler wire or electrode for your job.

The selection of the right welding electrodes or filler wire is an expert task performed by Welding Engineers based on factors:

Base material types, grade e.g. Stainless steel or carbon steel, SS316, ASTM A106, etc.
Similar material welding or dissimilar welding.
Joining or weld overlay application.

Metallurgy of the material, its physical, and chemical properties.
Service conditions e.g. room temperature elevated temperature, deep-sea, etc.
Type of available welding process.

Availability of welding consumables in the market.
Type of welding joint and applicable welding stresses.
The thickness of the base metals to be joined

Anticipated cost, and quality requirements.

These are the main summary of the points to be considered for choosing a welding electrode although there are various other associated factors that need to be considered too.

Finding Electrode for different types of materials

An easy way to find an electrode for a known type of material is via ASME Section IIC. ASME IIC contains 36 SFA from SFA 5.1 to SFA 5.36. A summary of these SFA numbers and their material types is shown in the below table.

Use these charts to easily locate matching, suitable electrode or filler wire for welding to join various similar and dissimilar welding.

Welding electrode selection Chart for Carbon steel, Low alloy steel, Cr-Mo Steel

Welding electrode selection for carbon steel to carbon steel, C-Mo, Cr-Mo & Nickel steels are given in the below chart. Most of the carbon steel is welded using an E7018 stick rod or ER70S-6 TIG/ MIG filler.

These electrode’s deposit strength is higher than most commonly used carbon steel such as ASTM A36, ASTM A 516, S275 or S375, ASTM 105, A106, etc.

Refer to the below chart to find dissimilar weld combinations also. For example, if you wish to weld Carbon steel to 5Cr-1/2Mo, you can use E7018, E8018-B2, or E8018-B3 Stick rod or their equivalent TIG/ MIG filler such as ER70S-6, ER80S-B2 or ER80SB-3.

Welding electrode selection Chart for Carbon steel to stainless steel, All Stainless Steel

The below chart gives very detailed guidelines for stick welding (SMAW) or equivalent TIG/MIG filler wires for different types of stainless steel welding.

In these consumables, XX means -15/ -16 or -17 type. For example, E309L-XX, you can use either E309L-15 or E309L-16, or E309-17.
