Paul Jones says
TIG welding is a precision arc process we rely on for stainless, mild steel and aluminium work in professional workshops and bodyshops. In day‑to‑day use it comes into its own on thin sections, brackets, pipework, custom panels and aluminium repairs where you need clean control of heat and a tidy weld appearance.
From a technical point of view, correct torch setup and gas coverage are critical. Use appropriate tungsten type and diameter, keep arc length short, and protect the pool with stable argon flow, especially when working in draughty bays. On aluminium, surface preparation is non‑negotiable: thorough degreasing and brushing with a dedicated stainless wire brush before striking up.
A common issue I see is operators jumping straight from MIG to TIG on thin material without adjusting their expectations of travel speed and heat control, which leads to warping or contamination. Given a suitable machine and a bit of practice, TIG is highly reliable and efficient for fine, professional repairs, provided it is set up carefully and used with respect for cleanliness and heat input.
