In　this　paper,　the　related　influencing　factors,　detection,　control　and　generation　mechanism　of　hexavalent　chromium　(Cr　(VI))　in　stainless　steel　welding　fumes　were　reviewed　and　analyzed.　It　was　found　that　the　proportion　of　amount　of　Cr　(VI)　in　the　whole　Cr　in　the　fumes　increased　with　the　increase　of　oxidation　of　welding　shielding　gas.　The　K　and　Na　elements　in　welding　consumables,　having　tendency　to　cause　chemical　reactions　with　CrO42-　and　Cr2O72-　to　form　stable　Cr　(VI)　compounds,　should　be　limited　to　a　certain　range.　Furthermore,　the　solid-liquid　extraction　detection　method　has　remarkable　advantages　of　low　cost,　easy　operation,　and　suitable　for　the　quantitative　detection　compared　with　the　solid　species　detection　method.
