Improve welding technology for heavy-wall pressure vessels in creep-resistant steel

The standard practice recommended for high-pressure vessels with heavy wall thickness requires the implementation of weld joint preparation with a narrow gap technique. This generally calls for a two-beads-per-layer sequence, along with the use of the submerged arc welding (SAW) process.
