Solutions to Porosity Defects

In order to better address the porosity defects in spiral steel pipe welding, it is necessary to treat the weld surface based on the understood principle of porosity formation, which can effectively eliminate the influence of impurities such as moisture and rust on bubble formation. From the welding perspective, it is also necessary to make certain adjustments to the welding parameters so that the welding current and welding speed can meet the welding requirements, thereby reducing the probability of porosity defects. Furthermore, a comprehensive welding inspection should be conducted throughout the entire process. Starting from the arrival of raw materials, proper storage and preservation measures should be taken. Storage methods should be adopted in accordance with the characteristics of the welding steel plates to ensure that the steel plates are stored in a good environment, thus preventing rust and other phenomena. The processed steel plates should also be carefully inspected, especially the welding areas which require more in-depth inspection. Through inspection, potential problems can be identified and promptly addressed to improve the cleanliness of the welding areas, thereby effectively avoiding the occurrence of porosity defects.
