Welding properties of DIN 17175 10CrMo910 seamless alloy steel pipe

When DIN 17175 10CrMo910 alloy steel pipe is welded, if the welding rod and welding wire with the same strength as the base metal are selected, the plasticity of the welding joint obtained is poor, the preheating temperature is required to be 400-450 ℃, the preheating temperature is high, and the construction conditions are poor; in order to improve the plasticity of the welded joint, it is necessary to conduct 740 ℃ heat preservation for 3h high temperature tempering after welding. However, high temperature preheating and high temperature tempering for a long time will cause obvious softening of the HAZ.

 

If the electrode and welding wire with slightly lower strength and better plasticity are selected, the preheating temperature will be greatly reduced (actual operation 250-300 ℃), the high temperature tempering temperature will also be reduced, the tempering treatment time will be shortened, and 700-720 ℃ will be kept for 1H for tempering, which is enough to eliminate the welding stress and will not cause the softening of the heat affected zone of welding. Therefore, r317 electrode and h08crmoa welding wire are generally used for DIN 17175 10CrMo910 alloy steel pipe welding.
