TIG (Tungsten Inert Gas) welding is a precise and versatile welding process that is often used for welding mild steel. It’s an excellent choice for projects that require precise control of the weld, including thin materials and delicate jobs. However, it can be intimidating if you’ve never used it before. Here’s a beginner’s guide to help you get started with TIG welding mild steel.
Guide to tig welding
Gather Your Supplies
Before you start, ensure you have all the supplies you need for your project. You will need a TIG welder, tungsten electrodes, filler rod, and protective gear (helmet, gloves, etc.). You should also read the user manual for your welder to understand how it works and any safety precautions you need to follow when using it. Once you have everything ready to go, it’s time to begin!
Set Up Your Welder
Now that your supplies are gathered and ready to go, set up your welder according to the instructions in the user manual. This includes connecting the power cord and installing additional components, such as a foot switch or torch holder. Ensure all connections are secure and all parts function correctly before beginning your project.
Select Your Settings
Once everything is connected and ready to go, select your settings on the welder based on what type of material you are working with (mild steel). This includes choosing the amperage level, type of gas (argon or helium), electrode size/type (tungsten), filler rod size/type (ER70S-6 mild steel), etc. It’s important to take into account factors such as material thickness when selecting these settings, as they will influence how well your weld looks in the end.
Start Welding!
Now that all your settings are selected correctly for mild steel welding, it’s time to start welding! Begin by cleaning off any dirt or debris from the surfaces where you will be welding with a wire brush or sandpaper before starting. Make sure there is no oil either; if there is, use acetone or another degreaser product to remove it completely before beginning. Then start welding by slowly pushing down on the pedal while keeping an even pressure on both sides of the joint as you move along until you reach the end of your weld line. Make sure not to pause too long in one spot or pull away too quickly, as this can cause defects in your finished weld line. After finishing each pass over a joint, add more filler rods if needed before continuing until completion.
Conclusion
TIG welding is an excellent choice for precise control over delicate projects like mild steel fabrication projects. With some practice and patience, anyone can learn how to use this versatile process correctly for beautiful results every time! Just remember that safety comes first; always wear protective gear when operating a TIG welder and keep children away from work areas at all times for their safety, as well as yours! By following these simple steps, anyone can complete their mild steel fabrication projects using TIG welding techniques with beautiful results every time!
