Svetstråd ESAB OK Autrod 309LSi
Overalloyed extra low-carbon stainless steel wire electrode for gas metal arc welding of austenitic stainless steels (eg 316L and 308L) against ordinary unalloyed and low-alloyed steels. OK Autrod 309LSi is recommended for example for AISI 304, 404L and X5CrNi18-10 (SS2332, W. no.1.4301) and SS2333 or equivalent stainless steels according to other standards. It is also suitable for bottom strings in the transition between the stainless layer of the compound plate and the unalloyed one. The high silicon content results in good welding properties. For material thicknesses below 3 mm, short arc welding is easier to handle than spray arc welding. Bottom strands in chamfered joints are also most easily performed with short arc welding, while the remaining strands, at least in the case of horizontal welding, can be performed faster with spray arc welding.
