摘要
本文介绍了锻钢40CrMnMo小齿轮裂纹情况,分析了40CrMnMo的焊接性,以40CrMnMo小齿轮补焊为例,阐述了焊接工艺与抗裂性的关系。指出焊接工艺对提高抗裂性有直接影响,只有制定合理的焊接工艺才能确保焊接质量。
The cracks about forged steel 40CrMnMo pinion was introduced , and the weldability of 40CrMnMo was analyzed . Take defects welding repair of forged steel 40CrMnMo Pinion for example , the connection between the welding technology and the crack resistance was expounded .Pointed out that the welding technology has a direct impact to improve carack resistance , only compiled reasonable welding technology to ensure welding quality .
