If you are a beginner in TIG welding, then I have a couple of tips for you today. To be a great welder, you have to remain open minded. There’s so much more to learn, and there’s so much that you can do to improve your skills. What is TIG Welding? TIG welding is a type of welding that can be used to weld copper, titanium, or even two dissimilar metals. Most welders turn to TIG when they have to weld something that is complicated or tricky. How does TIG Welding work? TIG Welding works by generating heat via an arc of electricity that will jump from an electrode – which is usually a tungsten metal – to the metal surface of what you are going to weld – which is usually aluminum or steel.
TIG stands for Tungsten Inert Gas.
To begin with TIG WELDING, you will need to find the right electrode. The electrode holds an important part of the weld. As I said above, TIG welding works by generating heat through the electrode to the metal surface. Here’s a tip: TUNGSTEN ROD IS THE BEST FOR ALUMINUM. Keep in mind that some electrode needs to be grind before you can use this, especially if it is a brand new cylinder and it doesn’t have a pointed or a rounded tip yet. What is the relevance of the tip? You see, if the tip of the electrode is pointed, you will have a smaller and more directed arc. However, if the tip is a little bit rounded, then the arc will have the possibility of dancing around.
Note that as you continue using the rod, the tip will become rounded because of the heat so you may need to grind it again. Keep track of this as this could affect your weld.
When insert the electrode into it’s protective sheath, it should be about 1/4 inch away.
Please familiarize yourself with the typical TIG rig. It has three main electricity options which are AC, DCEP, and DCEN.
If you are welding Aluminum, choose “AC”. In the cleaning or penetrating, you will turn it more to the penetrating at about 7 in the scale of 1 to 10. “AIR ON” for 5 seconds. This is the length of time that the gas stays on after the arc will stop. It will help keep your weld from oxidizing or rusting.
• DCEP means “DC, Electrode Positive”. You can use this setting when balling the tungsten tip or during stick welding.
• DCEN means “DC, Electrode Negative”. You can use this setting for welding steel.
When it comes to gas:
PURE ARGON for ALUMINUM.
A mix of ARGON and CARBON DIOXIDE for STEEL.
The gas keeps the weld from becoming corroded, rusting, or oxidizing.
When it comes to where you are welding, any flat metal surface will do. If you have extra budget, you can purchase a welding table. This large metallic area is a necessary factor to let the electricity flow through your metal.
Remember too clamp your metal down before welding or they will keep on moving around.
You can also use anti-spatter sprays before starting.
