Key Parameters in TIG Welding
Amperage, voltage, and gas flow are the primary settings that ensure weld quality and consistency. Adjusting these parameters correctly is essential for achieving precise, high-quality TIG welds.
3.1 Amperage Settings
Amperage settings in TIG welding determine the intensity of the arc and penetration depth. Higher amperage increases heat input, suitable for thicker materials, while lower settings are ideal for thin metals. For example, mild steel typically ranges from 50-150 amps, stainless steel from 30-120 amps, and aluminum from 20-100 amps. Proper adjustment ensures optimal weld quality and avoids overheating or lack of fusion.
3.2 Voltage Settings
Voltage settings in TIG welding influence the arc length and width, impacting weld penetration and appearance. Typical voltage ranges are 10-25 volts, depending on material thickness and type. Higher voltage increases arc length, suited for thicker materials, while lower settings provide focused, precise welds. Proper voltage adjustment ensures consistent arc characteristics and prevents issues like porosity or lack of fusion. Always refer to a settings chart for material-specific recommendations.
3.3 Gas Flow Settings
Gas flow settings in TIG welding are critical for maintaining an inert atmosphere, preventing contamination. Argon is commonly used, with flow rates between 10-25 CFH. Helium or argon-helium mixes are used for thicker materials. Proper gas flow ensures a clean weld pool and prevents porosity. Excessive flow can waste gas, while too little may allow atmospheric contamination. Always consult a settings chart for material-specific gas recommendations.
Material-Specific Settings
Material-specific settings ensure optimal weld quality by tailoring parameters to the type and thickness of the metal. Stainless steel, aluminum, and mild steel each require unique configurations for best results.
4.1 Mild Steel Settings
Mild steel TIG welding typically uses amperage settings between 80-150 amps, depending on material thickness. A 2% thoriated or lanthanated tungsten electrode is recommended for optimal arc stability. Gas flow rates of 10-20 CFH argon are standard to maintain an inert atmosphere. Cleanliness and proper joint preparation are crucial to avoid contamination and ensure strong, defect-free welds. Adjustments may vary based on specific alloy types and desired weld penetration.
4.2 Stainless Steel Settings
Stainless steel TIG welding typically requires amperage settings between 80-180 amps, depending on the grade and thickness. A 2% lanthanated tungsten electrode is preferred for its durability and arc stability. Use argon gas with a flow rate of 10-20 CFH to prevent oxidation. Maintain a clean, oxide-free surface and consider using a foot pedal for precise heat control. Post-weld cooling helps prevent discoloration and maintains corrosion resistance.
4.3 Aluminum Settings
For aluminum, use AC polarity with amperage ranging from 80-250 amps, depending on thickness. A 2% thoriated or lanthanated tungsten electrode is recommended. Argon-helium gas mix (75/25) at 15-25 CFH flow rate enhances penetration and reduces porosity. Clean the material thoroughly to avoid contamination. Maintain a steady arc length and cool the workpiece to prevent warping. Proper technique ensures smooth, crack-free welds.
Thickness and Welding Parameters
Material thickness significantly impacts TIG welding settings. Thinner materials require lower amperage and precise gas flow to prevent distortion. Thicker materials need higher amperage and often mixed gases for deeper penetration.
5.1 Thin Material Welding Settings
For thin materials, lower amperage and controlled gas flow are essential to prevent overheating. Settings typically range from 50-100 amps, with a focus on maintaining arc stability. Using a foot pedal allows precise control over heat input. Argon or helium gas mixtures are common, ensuring a clean, oxide-free weld. Proper torch angle and technique are critical to avoid distortion or burn-through in thin sheets.
5.2 Thick Material Welding Settings
Thick materials require higher amperage and gas flow to ensure deep penetration and strong welds. Settings typically range from 150-300 amps, with increased argon or helium flow for better shielding. Multiple passes may be necessary, and slower travel speeds help achieve full penetration. Proper cooling between passes prevents distortion and ensures structural integrity, especially in critical applications like heavy machinery or construction.
Tungsten Electrode Selection
Tungsten electrodes are crucial for TIG welding. Choosing the right type, size, and grind ensures proper arc stability and weld quality for different materials, ensuring optimal performance and durability.
6.1 Choosing the Right Tungsten Type
Choosing the right tungsten type is crucial for optimal TIG welding performance. Thoriated tungsten is ideal for DC welding, offering better arc stability and penetration. Lanthanated tungsten is versatile for both AC and DC, reducing electrode wear. Pure tungsten is best for AC welding, especially with aluminum. The grind and tip shape further influence arc characteristics and weld quality, ensuring precise control and clean results.
6.2 Tungsten Size and Grinding
Selecting the correct tungsten size is essential for achieving desired weld penetration and arc stability. Larger electrodes are typically used for thicker materials and higher amperage settings, while smaller ones are better suited for precision welding on thinner materials. Proper grinding of the tungsten tip ensures a consistent arc and prevents contamination. The TIG welding settings chart PDF provides detailed recommendations for tungsten size and grinding techniques based on specific welding applications for optimal results.
Polarity and Arc Characteristics
Polarity and arc characteristics are crucial in TIG welding, affecting weld penetration and quality. The settings chart helps optimize these parameters for consistent results effectively.
7.1 AC vs. DC Polarity Settings
AC polarity is ideal for welding materials like aluminum, offering a cleaning effect, while DC polarity suits steel and stainless steel, providing deeper penetration. A TIG welding settings chart guides the selection of AC or DC polarity, ensuring proper amperage and arc stability. This helps achieve precise control over weld quality and penetration for various materials and thicknesses effectively.

Welding Technique and Torch Angle
Proper torch handling and maintaining the correct angle are crucial for TIG welding. This ensures consistent weld quality, penetration, and aesthetic appeal. Mastery requires practice.
9.1 Proper Torch Handling
Proper torch handling in TIG welding is essential for precision and control. Hold the torch at a 15-20° angle, with a consistent grip to maintain stability. Use a pushing or dragging technique depending on the weld type. Keep the tungsten electrode at the correct distance to avoid contamination and ensure proper gas flow. Practice torch movement to achieve smooth, steady welds.
9.2 Maintaining the Correct Angle
Maintaining the correct torch angle is crucial for achieving high-quality TIG welds. The ideal angle typically ranges between 15° and 20°, depending on the material and technique. For thin materials like aluminum, a shallower angle may be used to prevent excessive heat input, while thicker materials might require a slightly steeper angle for deeper penetration. The angle also varies with techniques: when “pushing” the torch, the angle is slightly away from the weld direction, whereas “dragging” involves angling the torch toward the weld pool. Proper angling ensures even heat distribution, effective gas shielding, and optimal weld penetration. It’s essential to adjust the angle based on the specific material, thickness, and desired weld properties, as outlined in a TIG welding settings chart. Practice and experience will help refine your ability to maintain the correct angle consistently.
Troubleshooting Common Issues
Common TIG welding issues include porosity, lack of penetration, and inconsistent weld quality. Adjusting settings like amperage, gas flow, and torch angle can resolve these problems effectively.
10.1 Identifying Porosity and Lack of Penetration
Porosity and lack of penetration are common issues in TIG welding. Porosity appears as small pits or bubbles in the weld, often due to improper gas flow or contamination. Lack of penetration occurs when the weld fails to fully fuse the base metal. Both issues can be diagnosed by examining the weld’s surface and cross-section. Adjusting amperage, voltage, and gas flow settings, as guided by a TIG welding chart, helps resolve these problems effectively.
10.2 Adjusting Settings for Optimal Results
Adjusting TIG welding settings requires fine-tuning amperage, voltage, and gas flow based on material type and thickness. Proper settings ensure strong, defect-free welds.
