Can carbon dioxide gas shielded welding be used for welding pressure pipelines?
Use is restricted. . It is necessary to distinguish between gas metal arc welding with a reactive gas shield and gas metal arc welding with an inert gas shield
MIG welding – this is widely used, right?
Steel structures are used frequently, while pressure vessels are less common
Yes, it is possible; before proceeding, it is necessary to evaluate the welding process (by consulting the local quality supervision agency) and prepare a welding procedure card. As long as it has undergone process evaluation and passed, it can be used.
Generally, manual welding can now be used for filling seams in WPS; this type of WPS is acceptable, but its efficiency is usually not high. Additionally, automatic welding is becoming increasingly popular in container manufacturing.
Question: Is there a clear specification in the standards?
It’s usually not done; there are better welding processes available. Who would want to take the risk? At least, normal designs don’t do this
