Comparative Study on Pulse Current Repair of Multi⁃Cracked High⁃Pressure Elbows

Shiyou jixie
Affected by environmental corrosion， internal load impact and thermal processing defects， high-pressure elbows develop micro-cracks， often appearing as multiple cracks with highly random distributions， which puts forward higher requirements for the pulse
