Which electrode for which thickness?

Which electrode for which thickness?

How do you choose an electrode thickness?

Generally the size of the electrode that should be used depends on the thickness of the part to be welded. For thin metals the electrode is only slightly larger than the metal to be welded. For example if a plate is of 2.0 mm thick the electrode of 2.5 mm should be used.

How do I know which electrode to use?

First, select a stick electrode that matches the strength properties and composition of the base metal. For example, when working on mild steel, generally any E60 or E70 electrode will work. Next, match the electrode type to the welding position and consider the available power source.

What is a 6013 electrode good for?

The 6013 electrode is best used for light to medium penetration on thin or sheet metal pieces. 6013 electrodes are commonly used in manufacturing truck frame bodies, metal furniture, storage tanks, farm implementations, or where aesthetics are of grave importance.

What size is 6013 welding rod?

6013 Welding Electrodes – Size 1/16 – Qty 38. A light to medium penetrating all-purpose stick electrode for use in all positions, on carbon steel. Runs on AC or DCEP (reverse) polarity or DCEN (straight) polarity. 60,000 PSI tensile strength.

What is 2F and 3G means?

2 refers to a horizontal position – either 2F or 2G. 3 is a vertical position – either 3F or 3G. 4 is an overhead position – either 4F or 4G.

What factors should be considered when selecting an electrode size?

Electrode size – Electrode size should depend on the electrode type, welding position, joint preparation, base metal thickness, and skill of the welder.

What are the factors in selecting an electrode?

Factors you should consider when selecting a stick electrode include base metal type, joint fit-up and welding positions. Before you power up your machine and pick up your electrode holder, consider these basic guidelines.

How do you know what size welding rod to use?

As a general rule, for single-side single-pass butt welds, up to 3/16″ metal thickness, you choose a welding rod that is a step thinner than the base metal. For example, if the base metal is 1/8″, you select a 3/32″ rod. However, the general rule is flexible.
