What is hot wire TIG welding?

Hot wire TIG welding is a sophisticated welding technique known for its precision and efficiency. It involves the use of a heated filler wire in addition to the traditional Tungsten Inert Gas (TIG) welding process. This innovative method preheats the filler wire, making it easier to melt and flow into the weld pool, resulting in higher deposition rates and improved penetration. Hot wire TIG welding is widely used in various industries, including aerospace, automotive, and oil and gas, where the need for precise, high-quality welds is paramount. It offers benefits such as reduced heat input, minimised distortion, and superior control over the welding process, making it an excellent choice for critical applications where the integrity and longevity of welds are crucial.

Corrosion Resistance

Hot wire TIG welding ensures a more precise and uniform cladding, resulting in superior corrosion resistance. This is crucial for extending the lifespan of pipes and valves in corrosive oil and gas environments.

Reduced Downtime

Hot wire TIG welding’s high deposition rates enable faster cladding, reducing downtime for maintenance and repair of critical components in the oil and gas infrastructure.

Enhanced Material Compatibility

The precise control of the hot wire TIG process allows for the deposition of various corrosion-resistant materials, such as stainless steel or nickel alloys, onto base materials, ensuring compatibility with the transported fluids.

Precise Thickness Control

Weld overlay cladding often requires precise control over the cladding thickness. Hot wire TIG welding allows for accurate control over the deposition rate and thickness, ensuring compliance with industry standards.

High-Quality Welds

Hot wire TIG welding produces high-quality, defect-free welds with minimal porosity or inclusions, which is essential for maintaining the integrity of critical oil and gas components.

Improved Welder Productivity

The faster deposition rates and ease of use associated with hot wire TIG welding can increase welder productivity, allowing for more cladding work to be completed in less time.

Minimised Heat-Affected Zone (HAZ)

The reduced heat input associated with hot wire TIG welding minimises the size of the HAZ, preserving the mechanical properties of the base material and reducing the risk of stress corrosion cracking.

Uniform Cladding

The process provides uniform coverage and minimal dilution between the cladding material and the base metal, resulting in consistent quality throughout the cladded surface.

Reduced Post-Weld Inspection

The consistency and quality of hot wire TIG welding reduce the need for extensive post-weld inspection and rework, saving time and resources.

Long-Term Cost Savings

While the initial setup for hot wire TIG welding may require an investment, the long-term cost savings are significant due to reduced maintenance, extended component lifespan, and improved operational efficiency.

Compliance with Industry Standards

Hot wire TIG welding allows for precise control over cladding thickness and quality, ensuring compliance with stringent industry standards and regulations.
