Stainless steel welded joint should be how to deal with?
The polishing of stainless steel weld joint for flat parts must be polished after welding, grinding should be butt head flattening before (sheet metal hammer hammer, must not be used to avoid injuries and other surface).
Stainless steel welded joint should be how to deal with? The polishing of stainless steel weld joint for flat parts must be polished after welding, grinding should be butt head flattening before (sheet metal hammer hammer, must not be used to avoid injuries and other surface). Choose disc wheel grinding wheel, abrasive particle size from coarse to fine, abrasive particle size order for:
1), 240 # and 280 # - W40 - W28 - W20 - W142) 240 # - W40 - W28 - W20 naked eye observation without the next working procedure after grinding crack, grinding wheel may not be polished stainless steel, carbon steel of polishing avoid carbon particle inlay in the stainless steel, make joint yellow rust.
2.不銹鋼焊接接頭的拋光接頭的拋光應選擇氧化鉻綠色拋光膏,拋光輪行走應在一個方向來回運動,用力程度應保持均勻一致。消除打磨痕跡,粗糙度與兩側母材盡量保持一致。
3.不銹鋼焊接接頭的酸洗及鈍化處理不銹鋼焊后,焊縫須進行酸洗、鈍化處理。酸洗的目的是去除焊縫及熱影響區表面的氧化皮,鈍化的目的應使酸洗的表面或拋光表面重新形成一層無色的致密氧化膜,起耐腐蝕作用。常用的酸洗方法有兩種:酸液酸洗和酸膏酸洗。酸液酸洗又分為浸洗和刷洗。浸洗法適較小部件,將部件在酸洗槽中浸泡25~45min,取出后用清水沖凈。刷洗法適用于大型部件用于,用刷子或拖布反復刷洗焊接接頭到呈白亮后,用清水沖洗。
