Abstract
Aiming at the hardness exceeding standard problems occasionally occur in inside weld and HAZ during spiral submerged arc two-steps welding production, taking X80M line pipe production as example, it studied the influence of parameter variation on inside weld and HAZ hardness through several adjustment tests, such as welding groove, matching parameter, welding parameters, welding process and so on. The results indicated that in the production process of X80M line pipe, adjusting welding parameters and welding process can effectively reduce the hardness of weld and HAZ to a certain degree, thus to ensure the mechanical properties of two-steps welding steel pipe.关键词
