4 REASONS E6010 WELDING ELECTRODES ARE THE PIPE WELDER’S BEST FRIEND

The E6010 welding electrode is optimum for pipe welding applications.

While you can use E6010 for many applications, the electrode has quite a few unique characteristics that make it ideal for working with pipe in the field.

The Association of Mechanical Engineers describes the E6010 this way.

E6010 [E4310] electrodes are characterized by a deeply penetrating, forceful, spray type arc and readily removable, thin, friable slag which may not seem to completely cover the weld bead. Fillet welds usually have a relatively flat weld face and have a rather coarse, unevenly spaced ripple. The coverings are high in cellulose, usually exceeding 30% by weight. The other materials generally used in the covering include titanium dioxide, metallic deoxidizers such as ferromanganese, various types of magnesium or aluminum silicates, and liquid sodium silicate as a binder. Because of their covering composition, these electrodes are generally described as the high-cellulose sodium type. These electrodes are recommended for all welding positions, particularly on multiple pass applications in the vertical and overhead welding positions and where welds of good soundness are required. They frequently are selected for joining pipe and generally are capable of welding in the vertical position with either uphill or downhill progression. Reference : ASME Section II part D (par. A7.1)

Let’s break this down.

1. E6010 ELECTRODES ARE EASIER TO WORK WITH OVERHEAD.

Pipe welders don’t get to work in the flat position all the time. When you’re welding in the field, you’re going to have to work out of position quite a bit, especially overhead.

With some electrodes that don’t cool quickly, working overhead is tricky because gravity wants to pull that molten metal right out of the weld, and down onto the welder.

The E6010 electrodes are often put in the “fast-freeze” category of electrodes. They cool quickly. That makes them a good option for working overhead, since the molten metal stays in the weld, and does it’s job. It also doesn’t annoy the welder by falling down onto him as much.

Here’s a novice that does a great job explaining—and entertaining!

2. E6010 ELECTRODES ARE MORE FORGIVING FOR POOR JOINT PREPARATION AND FIELD APPLICATIONS.

When you have to work on pipes in the field, you have to deal with grime and rust, and all kinds of less-than-prime conditions for welding. The E6010 electrodes have deep penetration that don’t balk at all to dig through rust, oil, dirt and paint. Those are the perfect attributes for working with nasty, rusted pipes in the field.

3. E6010 ELECTRODES ARE BETTER FOR RUNNING STRINGER BEADS ON PIPE.

When pipe welders are doing a root pass, they typically are using a whip motion with laying the beads. By whipping the electrode a little upward and ahead of the weld, the welder allows the metal to cold down. The amount of whipping action is determined by the level of heat. The E6010 are perfect for this application because they cold down so quickly.

4. E6010 ELECTRODES MAKE IT EASY TO CLEAN THE SLAG OFF.

Once you’ve done your pass, it’s a time saver to be able to remove the slag quickly. The ASME refers to the slag as “readily removable, thin, friable.” That about sums it up. When you’re working in the field you want to minimize the clean-up time after a weld. The E6010 electrode makes that possible.

As a pipe welder, what are some other reasons that you use E6010 electrodes? We’d love to hear about them.
