Submerged arc welding is only possible on materials with high contents of iron, such as stainless steel. Its a relatively fast process, using an automatic or a semi-automatic device. While quick, it requires a lot of skill, as the arc needs constant protection from the flux to protect the parent material and the weld from outside elements.Estimated Reading Time: 6 minsWeld - Term PaperThe most successful process was submerged arc welding (SAW) where the arc is submerged in a blanket of granular fusible flux.

Jan 24, 2017 · The concentration of heat, characteristic of arc welding, is an advantage because less heat spread reduces buckling and warping. This heat concentration also increases the depth of penetration and speeds up the welding operation; therefore, you will find that arc welding is often more practical and economical than gas welding. All arc-welding processes have three things in common: a heat source, filler metal, and shielding.
