What are the factors that cause pores during steel pipe welding
There are many factors that affect the formation of porosity in steel pipe welding, for example, the type and content of the alloy composition of the electrode and the welding piece, the cleanliness of the electrode coating, the drying temperature of the electrode, the preheating temperature of the welding piece and the cooling speed of the welding seam, the skill and proficiency of the welding, the manner of welding and taming, whether there is the space location of the welding seam, even the thickness of the welding wave, the humidity of the air, etc.
