耐摩耗性複合鋼板: 構成と溶接工程

導入
A wear-resistant composite steel plate is a bimetallic material. ステンレス鋼製の複合層を接着することによって作成されます。, ニッケル基合金, 銅基合金, またはチタン - パーライト鋼のベース層に. この接合は爆発溶接などの方法で実現されます。, 複合圧延, and surfacing.

Welding Requirements
When welding wear-resistant composite steel plates, it is essential to preserve the material’s original properties. To achieve this, the base layer and composite layer must be welded separately. The choice of welding materials and techniques depends on the specific materials used in both layers.

The junction between the base and composite layers involves dissimilar steel welding. Plates with an austenitic stainless steel composite layer and a pearlite steel base are the second most common type, followed by those with ferritic steel as the composite layer.

Performance Requirements

• ベースレイヤー: Must provide the necessary strength and stiffness for the joint.
• Composite Layer: Should meet corrosion resistance and other performance criteria.

Welding Methods
Due to the variety of base and composite layer materials, several welding methods are used, 含む:

• Arc welding
• サブマージアーク溶接
• Tungsten inert gas (TIG) 溶接
• CO2 gas-shielded welding
• Plasma arc welding

Each method is chosen based on the material combination and required performance characteristics.
