What is a Push Angle in Welding?

The push angle is the angle between the electrode and the weld pool when welding in the flat position. This angle is also used to partially define the position of guns, torches, rods, and beams. The push angle is usually about 15 degrees for most welding processes but can be varied depending on the application.

The push angle is important because it affects the amount of heat that is transferred to the workpiece. If the push angle is too large, then the heat will not be evenly distributed and can cause warping or distortion. If the push angle is too small, then the weld bead will be narrow and may not have enough strength.

The push angle is also important because it can affect the penetration of the weld. If the push angle is too large, then the weld will not penetrate as deeply into the workpiece. If the push angle is too small, then the weld will penetrate too deeply and may cause problems with the root pass or other layers of the weld.

In general, the push angle should be between 10 and 20 degrees for most welding applications. However, there are some applications where a different push angle may be required. For example, when welding thin materials, a smaller push angle may be necessary to prevent penetration from happening too quickly. When welding thick materials, a larger push angle may be necessary to prevent warping or distortion.

It is important to experiment with different push angles to find the best setting for your particular application. The push angle can be adjusted by changing the position of the electrode or by changing the welding current.

Should you push or pull a weld?

The angle of the electrode relative to the weld pool plays a significant role in how the welding arc behaves.

Pushing the electrode into the weld puddle from above can help increase penetration, but it also increases the risk of burning through the workpiece. Pulling the electrode from below can help prevent burn-through, but it can also make it more difficult to achieve sufficient penetration.

In general, pushing is used for thicker materials while pulling is used for thinner materials. However, there are exceptions to this rule and ultimately it comes down to experimentation to see what works best for a particular application.

How to push MIG weld?

There are a few things to keep in mind when push welding with a MIG welder.

  1. First, it is important to use the correct electrode size and type. For most applications, a 0.045-inch (1.2 mm) electrode will work well. If you are welding thicker materials, then you may need to use a larger electrode.
  2. Second, it is important to set the correct welding current. A lower welding current will result in less penetration, while a higher welding current can cause burn-through.
  3. Third, it is important to use the correct gas mixture. For most applications, an argon/CO2 mix will work well. Fourth, it is important to maintain the correct push angle. Too much of an angle can cause burn-through, while too little angle can result in insufficient penetration.
  4. Finally, it is important to move the electrode at a consistent speed. A slow welding speed will result in more penetration, while a fast welding speed can cause the weld to be shallower.
