WALDUN hardfacing Service

Hardfacing with build-up layers, inspection and remanufacturing

Our WALDUN surfacing service offers professional hardfacing for a wide range of applications. This is where our first-class WALDUN hardfacing welding consumables combine with the latest welding technology and the skills of our experienced welders to provide individual, customized solutions.

By taking this approach, WALDUN maximizes the service life of components and assemblies which are exposed to wear, and ensures that plants operate effectively. Our service encompasses the design, implementation, and inspection of repair welding and overlay welding. This includes taking the parameters of the tribological system into account just as much as the properties of the base material. To ensure the best outcome, we check the design of (and need for) build-up layers and buffer layers, as well as calibrating the lower shelf/upper shelf positions in the wear model.

Maximum performance and effectiveness

On request, we will also check the effectiveness of your components, taking into account their individual requirements, the areas where the components are used, and their geometry. Since WALDUN is a system provider with a comprehensive portfolio of wear protection products, we are not limited to just one solution. This enables us to carry out an unbiased examination, and to propose designs for your plant components and assemblies which offer the ideal economic and technical balance.

In-situ welding — the refurbishment of components in their assembled condition — also forms part of the expert service that WALDUN offers to its customers worldwide. Our specialist welding equipment and portable power facilities, together with the particular know-how of our welders provide a guarantee of top-quality work, even in the tightest of maintenance windows.

Pipe Hardfacing Equipment

  • Wear-resisting pipe hardfacing equipment is mainly for the tube inside and outside wall, axis surface hardening surfacing. Using visible arc welding automatic welding. The roll overlaying welding machine has stable performance, simple operation, high degree of automation, powerful function, convenient maintenance, advanced technology etc.


PTA Welding Equipment

  • Plasma-transferred arc (PTA) welding is a thermal process for applying wear- and corrosion-resistant layers on surfaces of metallic materials. It is a versatile method of depositing high-quality metallurgically fused deposits on relatively low-cost surfaces. The PTA process is used in instances of extreme demands on wear resistance.

Precise-CNC-plasma-flame-cuttingPlasma Cutting Equipment

  • CNC plasma cutting machine collects rich experience of high precision machine building. Our machine table can secure you trouble-free at least 10 years! This machine euiped with Chinese or Hypertherm controller, and HD plasmas. All our machines are made according to high standard.

Chromium carbide wear plates

  • Chromium carbide wear plates or steel liners are used in many applications where friction between two parts or materials creates degradation. Wear plate steel plate may bolt onto a machine that slides in and out or up and down in a manufacturing process, while they can also be found where manufactured parts or minerals are regularly rubbing or abrasively contacting the machined plate.

What types of companies are buying wear plates?

Any company that has equipment with components that slide against each other or that are exposed to abrasive or corrosive materials or impact damage such as steel mills, pipe mills, aluminum mills, chemical companies, mining, military, etc.

Are there different types of wear plates?

Yes, wear plates and liners can be made from many different materials: Q235, Q345 are very common, other material can be used as base plate. Standard alloy can be changed in many different ways; it can improve the abrasion resistance while lowering the toughness, or the other way round. On the contrary, the matrix can be made harder by reducing the manganese to 1%, with some reduction in firmness. Also, further refinement may be accomplished by the addition of other alloying elements.

How are wear plates used?

Wear plates or liners are used to prevent damage to the main machinery due to abrasion or impact and to increase the life of the machine.

Examples of machines or components that might require wear plates or liners are:

  • Crushers
  • Shredders
  • Casting Equipment
  • Steel and Aluminum Mill Equipment
  • Heavy Earth Moving and Lining Equipment

Other applications for wear plates include:

  • Wear Blades
  • Choppers
  • Scrapers
  • Mining Tools
  • Chippers
  • Punch Press Applications
  • Punch Press Applications
  • Wear Rings
  • Wear Segments
  • Bucket Scrapers

  5. Delivery: We guarantee an on-time delivery accompanied by a flexible payment plan.
  6. Our company welcomes Fob, EXWORK, CIF and other trade terms.
  7. The packing is strictly in line with the customs requirements.

What else should I know before I order my wear plate?

You should know the what hardness of the plate is and what the intent is of the liner. The harder the plate that is used, the longer it will last in service, but there are trade-offs. For some parts, you will need a softer material that is intended to wear out before your primary surface.

Ordering a wear plate from WALDUN

In some cases, we can modify your equipment to incorporate these liner plates when not in the original equipment design. If your equipment has lost some efficiency or does not hold the same tolerances as new, inspect the worn parts. There could be an easy and cost effective fix to the problem.
