Fabrication Techniques for Precise, Repeatable TIG Welding

In fabrication, TIG only looks simple. Real results come from controlling variables before the arc even starts. This field-tested guide, Everything You NEED to Know About TIG Welding, distills core fabrication techniques into clear, repeatable steps—so your welds hold tolerance, pass inspection, and look the part. From prep to final pass, you’ll learn how fit-up, edge treatment, root gap, and fixturing set the stage; how amperage, travel speed, and heat sinking protect the HAZ; and how cup size, gas lens selection, and purge strategy lock in shielding on stainless, aluminum, chromoly, and titanium.

Built by career TIG specialists and refined on shop floors, the manual gives you structured process sheets, decision trees, and settings windows you can apply regardless of machine brand. Expect practical detail: tungsten geometry for AC and DC, filler selection by joint type and base metal, AC balance/frequency for thin aluminum, purge setups for sanitary stainless, distortion control on long seams, and proven troubleshooting paths for porosity, undercut, and lack of fusion. If you want fabrication techniques that turn guesswork into control, this is the reference you keep open at the bench.

• Faster fit-up and cleaner roots with less rework
• Lower distortion and tighter tolerances on thin sections
• Consistent, inspection-ready beads across positions and alloys
