Welded nozzles on the plate
Thread Content
Holes are made in a circular plate and nozzles are welded to it – what welding method should be chosen? ? There are also no specifications for welding holes in circular plates in GB150; should one design it based on own judgment? ?
The welding method is determined based on the plate thickness; there are plug-type and placement-type methods.
Is it to check GB150? Or other welding standards?
Well, one can refer to GB150, or alternatively use the node diagrams in HG/T20583-2011 for welds connecting the nozzles to the shell to select an appropriate node structure.
