不锈钢管高频感应焊接的探讨

为了解决不锈钢管焊接中氧化的负面影响，介绍了高频感应焊原理，并对不锈钢材料特性、焊接质量要素、机组性能、母材钢带及调整工技能和高频焊机功能等焊接工艺要素进行了分析探讨。认为不锈钢的化学成分、组织结构，材料电阻率、导磁率、热膨胀系数、热传导、弹性模量等都是影响不锈钢高频感应焊质量的重要因素，提出采用独立控制频率与功率的高频焊机，结合恰当机组设计与操作方式，可解决焊接氧化物等不利因素，提高焊接质量和焊接效率。

Discussion on High-Frequency Induction Welding of Stainless Steel Pipe

In order to solve negative effects of oxidation in stainless steel welding, the theory of high-frequency induction welding was introduced, and characteristics of stainless steel, elements of welding quality, performance of unit, parent metal steel strip, craftsmanship of operators, functions of high-frequency induction welder, and? some other welding process elements were analyzed. The results showed that important factors, which influenced the quality of high-frequency induction welding of stainless steel, included chemical composition, organization structure, resistivity, permeability, thermal expansion coefficient, heat conduction and elastic modulus; using high-frequency induction welder with independent controlling frequency and power and combining appropriate unit design and operation could solve negative effects of welding oxide and improve welding quality and efficiency.
