How to Choose the Right Welding Rod for Mild Steel

When it comes to welding mild steel, there are several factors to consider before selecting the right welding rod.

The first thing to consider is the thickness of the metal you will be welding. For thinner metals, a smaller-diameter welding rod is recommended, while thicker metals require a larger-diameter rod. The most common diameters for welding mild steel are 3/32", 1/8", and 5/32".

Another important consideration is the welding position. If you will be welding in a flat position, a smaller diameter rod will work well. However, if you will be welding in an overhead position, a larger diameter rod may be necessary to ensure proper penetration.

It's also important to consider the type of joint you will be welding. For butt joints, a smaller diameter rod is recommended, while larger diameter rods are better suited for fillet welds.

When selecting a welding rod, it's important to consider the type of welding you will be doing.

For TIG welding, a high-quality mild steel rod like the PGN ER70S-6 5LB 1/16" x 16" is recommended for clean, slag-free welds.
For stick welding, the E6013 welding rod is a good choice for mild steel due to its tensile strength of 60,000 psi and all-position electrode capabilities.
