摘要
对管道进行在役焊接修复研究所面临的形势,分析了对管道进行在役焊接修复研究的必要性、紧迫性;介绍了在役焊接修复过程中存在的问题(烧穿和氢致裂纹),修复方法,国内外研究现状,焊接方法及焊接材料。论述了管道工业及管道修复业未来的发展前景。
According to the situation that in--service welding repairing of pressure pipeline laces, the necessity and urgency of research on the welding repairing technology of pressure pipeline are presented; and the existing problems such as burning through and hydrogen Induced Cracking (HIC), repairing methods, present research status of abroad and domestic, and welding methods and welding material are introduced. Finally the development prospect of pipeline and pipeline repairing industry are pointed out.
