TIG welding (GTAW) uses separate filler metal rods, allowing for much greater control over the arc, heat input, and weld puddle. This results in the highest quality, most precise, and cosmetically superior welds, which are essential for critical pressure piping, aerospace, and sanitary applications where filler metal purity is paramount.
'Cut Lengths' refers to the standard packaging of TIG welding rods, which are typically supplied in pre-cut, straight lengths of 36 inches (914mm) in plastic tubes or boxes for manual feeding into the weld joint.
Yes, specialized Stainless Steel TIG rods, such as TIG Rod ER309L (or ER309LSi), are specifically designed and widely used for performing dissimilar metal welds, like joining stainless steel to carbon steel, providing excellent strength and crack resistance.
For Duplex stainless steel, TIG Rod ER2209 is the standard. For extreme corrosion environments like offshore and aggressive chemical plants, Super Duplex TIG Rod ER2594 is recommended for its superior pitting and crevice corrosion resistance.
