The advantages of TIG Welding include: Great for producing high quality welds on thin materials Can produce stronger joints than MIG and oxy-fuel processes Consistent joint thickness unlike FCAW (Flame cutting Arc Welding) or GMAW (Gas Metal Arc Welding) Can be used to weld joints in different positions and at different angles Can be used for joining pipes and tubes with thinner wall materials like stainless steel or aluminum as well as thicker materials like mild steel.
