旋转变压器技术以及180～360 Hz电流焊接技术得到快速推广,经过长时间的生产实践和质量控制经验积累,低频电阻焊管生产技术日趋成熟。本文将从装备、操作和质量控制等方面概括性地介绍低频电阻焊管生产的全过程。
Resolver technology and 180 ~ 360 Hz current welding technology has been rapidly promoted. After a long period of production practice and quality control experience accumulation, the production technology of low frequency resistance welded pipe is maturing. This article will outline the whole process of low-frequency resistance pipe production from the aspects of equipment, operation and quality control.
