How TIG Filler Wire Works
- Arc Initiation: The TIG welding process begins with an electric arc struck between a non-consumable tungsten electrode and the workpiece.
- Filler Wire Addition: As the arc melts the base material, the filler wire is introduced into the molten pool. The heat from the arc melts the filler wire, allowing it to blend with the base metal.
- Shielding Gas: A shielding gas, such as argon or helium, is used to protect the weld area from atmospheric contaminants that can cause defects.
Types of TIG Filler Wire
The choice of filler wire from the Shop Castron Electrode depends on the base materials being welded and the desired properties of the weld. Common types include:
ER 308L TIG Filler Wire
ER 308L TIG Filler Wire is a popular type of filler wire used in TIG welding, particularly for joining austenitic stainless steel components. It offers a good balance of strength, ductility, and corrosion resistance, making it a versatile choice for various applications.
ER312 TIG Filler Wire
ER312 TIG Filler Wire is specifically designed for welding austenitic stainless steels requiring high strength and toughness. It offers excellent mechanical properties, making it suitable for critical applications where reliability and durability are paramount.
ER 4043 TIG Filler Wire
ER 4043 TIG Filler Wire is used mainly in industries such as aerospace, automotive, marine, and construction, where aluminum alloys are employed. It is a popular filler wire used in TIG welding for joining aluminum alloys, particularly those in the 4000 series. It offers a good balance of strength, ductility, and corrosion resistance, making it a versatile choice for various applications.
Factors to Consider When Choosing Filler Wire
- Base Material Compatibility: The filler wire must be compatible with the base materials being welded to ensure a strong and reliable joint.
- Weld Strength and Ductility: The desired properties of the weld, such as strength and ductility, should be considered when selecting the filler wire.
- Corrosion Resistance: If the weld is exposed to corrosive environments, a filler wire with good corrosion resistance is essential.
- Filler Wire Diameter: The diameter of the filler wire should be chosen based on the thickness of the base materials and the desired welding speed.
Overall, TIG welding wire and weld products are perfect for welding and other industrial applications.
