Integral Welding Rod


The integral welding rod is a high-performance structural component designed for demanding industrial applications where strength, stability, and precision are essential. With a dense internal structure and reliable material properties, it supports long-term use under complex working conditions.

A wide range of materials is available, including 45# steel, 40Cr, 42CrMo, and stainless steel, allowing flexible selection according to requirements for mechanical strength, toughness, wear resistance, and corrosion resistance.

Manufactured with accuracy grades from F5 to F9, the integral welding rod ensures excellent dimensional consistency and operational stability, making it suitable for assemblies and welded structures with strict requirements on alignment and surface quality.

The diameter range from Φ20 to Φ500 enables broad applicability across different equipment sizes and engineering designs. Precision machining can be carried out strictly in accordance with customer drawings, supporting customized and application-specific solutions.

To further enhance surface performance, hard chrome plating with a thickness of 0.010mm to 0.10mm can be applied, significantly improving wear resistance, corrosion resistance, and surface finish, thereby extending service life and reducing maintenance needs.
