| Abstract: | This article introduced characteristic and application of self-shielded flux-cored wire semiautomatic welding for thick wall steel pipe,consider the common pipe materials and welding consumables,the reason of welded joint contains much hydrogen for self-shielded flux-cored wire semiautomatic welding are analyzed and the measure of reduces the contents of hydrogen of thick wall steel pipe welded joint for self-shielded flux-cored wire semiautomatic welding are proposed. |
| |
| Keywords: | self-shielded flux-cored wire semiautomatic welding contents of hydrogen control measure |
