Weld Overlay Plate

Equipment in multiple industrial contexts faces significant wear problems, and this makes finding effective solutions to protect against wear an important priority. Shandong Qishuai Wear-Resistant Equipment Co., Ltd. produces plates using overlay welding that provide protection for equipment.

The weld overlay plates that the company produces are composite plates. These plates use a process that applies layers of alloy material onto ordinary steel plates. The alloy material shows high hardness and high resistance to wear. The steel plates function as the base in this structure. The plates consist of ordinary steel with a layer of alloy material on the surface that resists wear.

The base uses steel plates that provide strength but also show low cost. These include Q235, Q345, or 16Mn steel types. The base provides structural support and also provides toughness for the plate. The base supports the layer that resists wear. The alloy layer on the surface is the main component for resisting wear in the plate. The composition of this layer uses specific materials. These materials allow the layer to resist different forms of wear. The wear forms include impact wear, wear from abrasive materials, and wear that occurs at high temperatures.

The plates are available in different specifications. The thickness of the base plate and the thickness of the wear layer that covers it can be adjusted. This allows the plates to meet requirements for different applications.

This meticulously engineered composite structure endows Weld Overlay Plate with numerous core advantages, setting them apart from other wear-resistant materials and making them the ideal choice for enhancing equipment performance and reducing costs.

Five Outstanding Advantages:

The material shows five main features that relate to performance. The service life that this material provides differs from standard materials used in similar conditions. Data indicate that resistance to wear shows values between five and ten times the level found in other steel plates designed for wear resistance. This pattern suggests significant differences in the extent to which the material maintains function over time.

The base structure of this material demonstrates particular features relating to toughness. It allows resistance to impact and vibration at moderate levels and these conditions occur without producing fractures in the material. This characteristic indicates that the material maintains structural form when forces affect it during use.

The material allows processing using different methods despite the high hardness that it shows. Cutting procedures apply to this material and bending also occurs within particular thickness ratios that the specifications establish. Welding methods also apply to the material and these approaches provide flexibility in how it develops into final forms for use.

The material provides value that differs from solid steel types that contain high alloy levels. The costs that this material requires appear lower than the costs for other materials and this difference suggests that the approach offers advantages in terms of the relationship between performance and the resources required to obtain it.

Production methods for this material allow customisation that addresses particular requirements. The approach responds to specific conditions that occur during operation and dimensional requirements that different uses establish. This feature indicates that the material develops through processes that consider the particular factors relating to how it functions in different contexts.

Rigorous Material Selection

In the production of our wear-resistant plates， material selection constitutes the critical first step. We meticulously screen every raw material to ensure its quality and performance meet stringent standards. The substrate employs premium low-carbon or low-alloy steel plates sourced from renowned domestic steel mills. These mills deliver products with stable chemical compositions and excellent mechanical properties, providing a robust structural foundation for weld overlay plates. Concurrently, we maintain long-term partnerships with multiple internationally renowned alloy material suppliers, guaranteeing the high purity, low impurity content, and exceptional performance of the alloy materials used for the wear-resistant cladding layer.

Each batch of raw materials is accompanied by detailed quality certificates. We subject these materials to rigorous inspection and verification to ensure that indicators such as chemical composition and mechanical properties align precisely with the specifications stated in the certificates.

Self-shielded arc fully automatic surfacing welding process

To further optimise the welding process, we have assembled a team of specialist welding engineers. Possessing extensive experience and profound expertise, they are capable of precisely adjusting welding parameters—such as welding current, voltage, welding speed, and wire feed rate—according to varying product specifications and operational requirements. This ensures the overlay weld layer achieves optimal quality and performance.

Quality Inspection of Welded Overlay Plates

For visual quality assessment, we employ a combined approach of manual visual inspection and high-precision optical detection equipment to conduct comprehensive surface examinations of welded overlay plates. This ensures surfaces are free from defects such as porosity, cracks, slag inclusions, and lack of fusion, while verifying uniform overlay thickness and surface flatness compliance with standard requirements. For hardness testing, specialised equipment such as Rockwell and Vickers hardness testers is employed. Following the testing methods and point distribution specified by national standards, hardness measurements are taken on both the overlay layer and the base plate to ensure hardness values meet product design requirements.

We also provide products to testing organizations that examine quality in a complete assessment. This approach confirms that the systems for control function as required and that products maintain reliability in their characteristics. The reports that result from these assessments show evidence supporting the level of quality and provide a basis for work that continues to improve standards in products. These findings indicate that the methods used allow ongoing development in the measures applied to production processes.
