Arc welding is one of the most basic types of welding there is and there are a lot of different welding techniques now available. This form of welding utilizes a power supply in order to generate enough heat between the electrode and the surface to be worked on to melt metals. There are variations to this form of welding. You can use alternating current or direct current electricity and you can also use consumable electrodes or ones that are non consumables.
Welding is a skill that can be mastered by anyone, but it is not something that you can study by reading books about theories and stuff like that. Arc welding and any other type of welding can only be mastered by constant practice. You need to do it a lot in order to hone your skills in it. Here are some tips that you can keep in mind when you are doing arc welding. These tips will help ensure the quality of your work and your safety as well:
1. Safety Measures
Before you start doing your welding work, you need to ensure your safety first. The welding electrodes emit strong UV light and so your eyes and your skin must be protected from exposure. Keep in mind that wearing welding helmets and welding gloves when welding is a must.
2. Rod and Arc Adjustment
This is the most sensitive and crucial part of the arc welding process. If you are just starting out in welding it is better to practice on a rusty piece of metal first. You need to find the right ampere setting for your welding work. The polarity setting has to be changed as well. Rod angle should be 10 degrees or 20 degrees. The distance of the arc should also be considered to make sure that it is short enough. You will know when the distance is short enough by the crackling sound that it generates once the electrode touches the metal surface.
3. Preventing Arc Welding Holes
As we have mentioned practice is the only way that you can master welding techniques. It is the only way too that you can discover the right settings for your machine. For example if the ampere of your welder is too high that might result in arc welding holes on the surface of the metal that you are working on.
4. Preparing the Surface
Before you start welding, you need to make sure that the surface of the metal that you are about to work on is clean and free from any dirt. An unclean surface might affect the result of your weld. You need to check the welding gun and the electrode as well and make sure that they are free from any form of contamination. That can also affect you welding work in a bad way.
5. Starting the Weld
In arc welding there are two common ways of starting the arc. The first method is by tap starting which is done by hitting the tip of the electrode to the surface which will then remove a small part of the flux from the electrode starting the arc. Scratch starting is also similar but the electrode has to be scratched on a coarse metal surface in that method.
Practicing these 5 tips will ensure that your process as a welder and your skills in welding become finely honed. The best welding skills of course attract the most money too.
