Precautions for cracks and pores in the 1045 seamless steel pipe


In the process of 1045 seamless steel pipe welding, after exterior inspection and X-ray nondestructive inspection, surface cracks appear on the 1045 seamless steel pipe welding appearance and defects such as pores exist inside the welding seam.

In order to ensure the quality of the 1045 seamless steel pipe welding welding seam, the following aspects should be pre-checked:


(1) strictly control the 1045 seamless steel pipe welding welding process parameters and reduce the cooling speed. Improve appropriate ratio of weld, the small current short arc does not swing or small oscillation, the multi-level multi-channel welding of reduce weld the degree of oxidation. 

(2) reasonable selection and line energy 1045 seamless steel pipe welding welding process parameters, such as preheating before welding and heat treatment after welding, the reasonable control.  

(3) alkaline welding rod welding interlayer temperature for drying before 1045 seamless steel pipe welding welding processing, drying temperature is 350, drying time is 1. 5 hours. 

(4) cleaning before welding to welding parent 1045 seamless steel pipe welding surface 20 mm in water pollution oxide, rust.  

(5) reduce the 1045 seamless steel pipe welding welding speed, make the internal gas easy to overflow, adjust welding process parameters.


Katalor has more rich experience in the 1045 seamless steel pipe welding, we have been export 1045 seamless steel pipe welding to all over the world. Of course we can supply 1045 seamless steel pipe welding with different sizes and good quality to meet your any requirements. Please contact us about 1045 seamless steel pipe welding!
