In response to the transverse cracking problem of 30CrMoA sucker rod steel during the metal deposition process,macroscopic analysis,chemical composition analysis,and microstructure analysis were conducted,and the operation process of the deposited metal was observed.An experimental comparison scheme was designed to verify the results.The results indicate that the transverse cracking of the sucker rod is not caused by the raw material,but by improper operation during the deposi-tion metal processing.
