For today’s topic, we are going to be talking about the pinholes that appear during welding. You may think that pinholes that appear on your weld isn’t noticeable, but let me tell you that it is, especially if you have a keen eye for detail. If you don’t take care of it as early as you can, it could be a starting point for rust.
We all know that welding is the art or craft of molding or joining two pieces of metal together with the help of either heat or electricity. It is a popular profession these days, and it pays well. Of course, every welder wants to give their best at the task that has been assigned to them and that is why seeing pinholes or sometimes called as “Porosity” is not a sight to behold. In fact, this is considered as a defect in the welding world. There are lots of reasons as to why pinholes were formed in your weld, but good thing about this is you can do something about them.
if the pinhole is in a round shape, it’s technical term is “Spherical Porosity”. However, if you look at it closely and notice that it is a little elongated, then that is called “Piping” or a “wormhole”.
Keep in mind that even if Pinholes are considered as a defect, they aren’t serious defects. However, your finished product might be rejected because of them. They are not a pretty sight to see, especially if they can be found at places that they aren’t supposed to be in. So to get to the point, what can you do about them?
You can cover them up with an epoxy. Here’s an example:
