Minerals, 2022 Chromium alloying of weld metal is usually accomplished via weld wire. This is done because chromium has a high affinity for oxygen and is therefore not easily transferred across the arc. The formation chromium (VI) is one of the main concerns in welding

Single sided single pass submerged arc welding of austenitic stainless steel [PDF]
, 2007 The weld metal produced from a series of high productivity welds of 316LN austenitic stainless steel plate was examined to evaluate the effects of the use of a higher heat input process (> 2.5kJ/mm).This high heat input process was aimed at maximising ...

SUBMERGED WELDING WITH PULS ARC
, 2022 The features of submerged arc welding with a pulsed arc (SWPA) have been studied. It is shown that an appropriate choice of SWPA parameters makes it possible to change the flows distribution in the weld pool and the thermal cycle characteristics of welding. With a constant heat welding input, the welds made by SWPA have a 20 ... 25% greater penetration
