Box welding could be the first practice if you are a beginner but would love to try to weld something. The steps are quite straight forward:
It looks easy, doesn’t it? The devil is in the details. I will show you step by step to see how I did the metal box.
Now, let’s begin!
First, set up the equipment:
I used T.I.G. welding for this project.
First thing first, you need to set up the equipment.
Ok, now the equipment is ready.
Second, personal protective equipment:
Third, Bring your material and also some metal scraps for testing:
If you are a beginner, it is always better to give a test before you start on your project. You will notice there is something going weird by hearing a strange noise from the torch or the machine, you may also realize the gas is not burning right by watching the color and the length of the flame.
This is an interesting tool that I want to introduce to you. It is made of magnetic metal. It has both 90 degree angle and 135 degree angle.
Once you put it on the metal desk, it will grab the surface tightly. The function of this tool is to hold the metal piece and secure it in its position. Super convenient and easy to use.
For the material part, I assume you have already cut the metal piece and used a file to sand the rough edge smooth.
Now, you are ready to weld!
(When you start to weld, you could feel the flame from the torch is heating the metal surface. Do not rush. Wait for a few seconds and you will see a small “pool” on the spot, like the metal is running like water. The filler should be melted in the pool, not by the flame or the torch.)
