Good Welds vs Bad Welds

Joining two pieces of metal together is not always as easy as you may want to find. While joining, there are good welds and there are bad welds.

If you are planning to start out or want to make your welding bead better in general, then if you have found the right article to guide you. After this, you will have no confusion about a good weld and a bad weld.

What Makes it a Good Weld?

An important skill to acquire for a welder is making a good weld. An art that not every professional welder possesses. The art of welding varies with its clean surface, gap management, and making a beautiful welding bead that joins two metals with each other like nothing else. Here we have talked about how you can make a good welding bead that will help you with your welding career.

Good welds mostly vary from your efficiency and experience. The cleaner you weld, the better it looks and the more efficient your welding becomes. However, creating a good welding bead is a combination of the three most important factors.

  1. Properly adjusted welder
  2. Good Weave Techniques
  3. Correct Travel Speed

First of all, Set your welder according to your welding guide. You can tune it as you would like to experiment or just set it up according to your set up guide.

1. Adjusted Machine Settings

A proper welding bead is a combination of balanced welding wire feed and voltage. The combination of these two things will result in proper convex shape and a smooth transition at the toes.

But if there is too much wire feed, the bead will be irregular and sit up higher. It may also have spatter all over the plate. Transition at the toes will not be as smooth as you would like.

To fix it; Either increase the voltage which will burn your wire faster or decrease the wire feed speed. It’s best to adjust one of these for easier control. But you should experiment both and see whats fit better for you.

If you have too little wire feed speed it will result in the bead to be wider and maybe a bit too convex.

To fix it, either decrease the voltage, which will burn off the wire slower or increase the wire feed speed. Again, experiment with both the technique and look to find out your sweet spot.

2. Good Weaving Technique

When you are welding two pieces of metal together, the materials actually melt. A good welding technique will make a slide weave to blend those two molten metals together and look as natural as its possibility can. 

There are several types of weaves that you can experiment with. You can use regular rock between the two plates slightly, you can use the half moon weave technique or the circles which would look like coins laying on a row. 

3. Perfect Travel Speed

Travel speed is an important factor while making a weld. If you travel too fast your weld may not hold for much longer; and if you travel too slow, you can get too much penetration, or even burn a hole at what you are welding. 

As a general rule, you want the side of the bead to build up to be as thick as the thinnest metal that you are welding. 

Final Words

So, That’s how you make a good welding bead and avoid bad ones. As we always say, experiment and experience are what make you a better welder. We offer you to make as many experiments as you like, find what works better for you and make the best possible version of your own welding technique.
