3.7 Electrode Angles (2024)

FAQs

What is the correct angle for the electrode? ›

Electrode Angles

When you start welding, angle it 10-15° toward the direction of travel until you complete the weld and terminate the arc. For butt weld (joining two pieces of metal butted together), first hold the electrode so that it is pointing into the joint of the workpiece at an angle of 90°.

Answer: The two types of electrode angle are the travel angle and the work angle.

What are the working angles for the root pass on the horizontal Butt joints? 5 to 10 degrees below perpendicular, 20 degree travel angle.

A good rule of thumb is to maintain a weld bead width approximately two and a half times the diameter of the core wire inside the stick electrode for flat and horizontal welding applications. For vertical up welding, try to create a weld bead width around two and a half to three times the size of the core wire.

Work angle: With wire welding, hold the gun at a 10° to 15° angle into the direction you are pushing the weld. With stick welding, maintain a 20° to 30° lead angle in the dragging direction. With a fillet (tee) weld, hold the rod or wire (regardless of weld process) at a 45° angle between the two pieces of metal.

Use a 90-degree travel angle for a 3G weld, and a 45-degree angle for a 3F weld.

Electrode Angles

The work angle is the angle at which the wire is pointing at the weld joint. For lap and T-welds, the work angle is 45°, for butt welds, it is 90°. The travel angle is the angle of the wire as it travels along the weld path. For most wire welding applications, this angle is 15-30°.

Work angle is “the relationship between the axis of the electrode to the welders work piece”. Travel angle refers to employing either a push angle (pointing in the direction of travel) or a drag angle, when the electrode is pointed opposite of travel.

The two-electrode (or direct) method uses a regular geometry with two electrodes placed face to face (Figure 1 (a)). An alternating current is applied and the potential drop between the electrodes is measured. ...

To weld the second pass hold the electrode at about 45° angle fusing into the vertical plate and the first bead. Make multiple pass horizontal fillets as shown in the sketch. Put the first bead in the corner with fairly high current even though there may be slight undercut, succeeding passes will burn it out.

How do you get a perfect stick weld? ›

1. Ensure the cleaning of the material and place to be welded. Before starting any welding procedure, make sure that everything is free of impurities. Contamination damages the final result.

Tungsten Inert Gas (TIG) welding is widely considered the most challenging welding process to learn. The sheer complexity of the technique requires more practice and focus to master than other less-technical welding methods. TIG welding also results in some of the strongest and sturdiest welds in the industry.

A typical travel speed in TIG welding is 4-6 inches per minute. With MIG welding, travel speeds are much higher; 6 inches per minute are considered slow, and 15 to 20 inches per minute are common.

The two terms used to describe the electrode angle, or position, are the travel angle and the work angle. Figure 3-44. Travel angle in a groove weld. The travel angle is measured from the electrode axis to a line perpendicular to the weld axis in the plane defined by the weld axis and the electrode axis.

In vertical position slope remains between 45 and 90 degrees and rotation may have any value from 0 to 180 degrees. (4) Overhead position. The plane of the workpiece is horizontal; welding is carried out from the underside, electrode pointing upward.

As the angle between the electrode and the plate determines the point of impingement and direction of the arc force, it has a critical effect on the weld bead profile and depth of penetration.

As welding instructor who was trained as a welder in the Navy, I was taught and now teach that two electrode angles are required to control weld profile. One being the lead angle which is the forward or backward angle parallel to the weld axis and the other is the work angle which is perpendicular to the weld axis.
