With over 45 years of industry-leading experience, Manluk is proud to service a wide range of clients that depend on equipment that faces some of the toughest work environments you’ll find in North America and beyond. From oil sands mining to industrial processing, energy production and more, the longevity of your components is critical for project success and site safety. These demanding environments, however, can take a heavy toll on unprotected items. That’s why weld overlays are crucial for ensuring everything works properly and is protected when (and where!) it matters most.
At Manluk, we offer several overlay types and apply them using techniques that focus on precision, consistency, and real-world performance. Learn more below.
What Weld Overlays Do and Why They Matter
Weld overlays add a layer of wear-resistant material to the surface of a steel part. This enhanced layer helps absorb the abrasion, impact, and erosion that would normally damage the component, allowing the base material to remain strong and supportive underneath. Overlays are especially important in applications involving:
- Slurry and heavy particulate flow
- Abrasive sand or silica
- Crushers, chutes, and screens
- High-pressure industrial processes
- Rotating parts with friction or sliding wear
- Impact-prone environments
Without proper protection, these conditions cause significant damage and lead to costly downtime. Weld overlays help slow that wear and support a smoother, more reliable operating cycle.
Why Clients Choose Manluk for Weld Overlays
Experience matters when applying overlays and caring for components. The fact is, wear doesn’t develop the same way in every environment, and the geometry of a component can dramatically affect how long it lasts. That means every solution needs to be specifically tailored to the needs of your job site and equipment. Because Manluk has extensive experience working with oil sands mining and other heavy industries, we understand the wear patterns and how to apply coatings that perform when it matters most.
Our overlays help with:
- High-impact resistance for harsh operating conditions
- Consistent carbide distribution for predictable wear
- Accurate overlay thickness across the entire surface
- Clean transitions that support machining and assembly
- Controlled dilution that protects carbide performance
Types of Weld Overlays We Provide
At Manluk, we offer trusted overlay solutions, each with its own strengths and best uses, including:
PTA (Plasma Transferred Arc) Tungsten Carbide Overlays
PTA overlays offer the highest level of wear protection we provide, making them ideal for the extreme conditions found in oil sands and high-wear industrial environments. PTA welding utilizes a plasma arc to fuse tungsten carbide particles directly onto the steel surface, resulting in a dense and highly durable overlay.
PTA overlays are known for:
- Exceptional impact resistance
- High carbide concentration
- Reliable metallurgical bonding
- Uniform distribution of carbide
- Long service life
These overlays are typically used on components such as valve seats, pump parts, edges, cones, and components exposed to constant impact and high-pressure flow. Best of all, they deliver some of the best wear performance available.
Weld Build-Up and Restoration Overlays
Not all overlays are about protection. Some are used to restore worn parts. Build-up overlays help return shafts, housings, and rotating equipment to their proper size, allowing clients to reuse and salvage valuable components.
This process is especially valuable for maintenance programs aiming to extend equipment life without purchasing new components.
Part of a Complete Manufacturing Solution
One of the advantages of working with Manluk is that we do everything in-house. We prepare the base material, apply the overlay, machine the finished part, and complete all quality checks before it leaves our shop for a full-service experience that gives you:
- Shorter lead times
- Better control over quality
- Consistent results
- Improved predictability
- Faster rebuilds and repairs
Built for Real-World Performance
Weld overlays are an essential part of keeping industrial equipment running in abrasive, demanding environments. At Manluk, we apply overlays built to handle real-world conditions. Whether it’s cladding for heavy abrasion, PTA overlays for high impact, or build-up layers for restoration, our team delivers solutions designed to last.
