The differentiating factors in SAW flux

摘要

We are a pressure vessel shop that fabricates carbon steel vessels. Recently we looked into perhaps changing our flux to improve our SAW production. There are several types of flux, and it's a bit confusing on what makes them different and what we are allowed to use for our application. Can you shed some light on this? Yes, we can break it down and hopefully clear up any confusion you may have. Let's start by examining what role flux plays in the submerged arc welding (SAW) process and how it is manufactured and categorized.
