UTP Joining & Cladding

UTP Maintenance joining and cladding consumables are engineered for reliable welding of dissimilar steels, producing corrosion-resistant overlays, and controlling dilution in single- and multi-layer cladding applications. These alloys provide stability, consistency, and metallurgical performance in demanding temporary mining and industrial environments.

Applications in Mining & Heavy Industry

Joining and cladding alloys are used where standard filler metals fail or where specialized metallurgy is required. UTP Maintenance alloys are used on:

• Transitions between carbon steel and stainless steel

• Buffer layers before hardfacing or final overlay

• Corrosion-resistant surfaces for chemical exposure

• Repair of mixed or unknown steels

• Components requiring low-dilution cladding

• Heat-resistant or high-temperature surfaces

• Equipment operating in corrosive slurries or process fluids

• Any steel exposed to dissimilar joining challenges

Typical Joining & Cladding Problems

Common challenges in mining and heavy industry include:

• Differing thermal expansion rates leading to cracking

• Unknown or mixed base metals

• Dilution control requirements for corrosion resistance

• Need for buffer layers before final hardfacing

• High heat input sensitivity

• Stress concentration at material transitions

UTP alloys address these with tailored compositions—now enhanced with 2025 Cr-reduced formulas for fume safety.

Understanding Joining & Cladding Modes

Correct alloy selection begins with understanding the primary mechanism:

• Dissimilar steel joining – for carbon to stainless/tool/unknown steels with high crack resistance

• Corrosion-resistant joining/cladding – for acids/chlorides/seawater with low dilution

• Stainless steel joining & buffer – for toughness under impact/heat with work-hardening

Each mode requires specific alloys – which UTP alloys are engineered to provide.
