Welding of 904L pipe material
Thread Content
What should be noted when welding 904L? Is it the same as welding 316L? It is said online that welding and watering at the same time are required (to control the temperature); is this necessary? Also, is it necessary to use argon gas for welding? I have never used 904L; I hope those who have used it can share their experiences. Thank you
The temperature between layers needs to be controlled, but watering is not required; natural cooling is sufficient. Argon flushing is necessary, as is double-sided protection. Control the wire energy and be mindful of welding hot cracks.
