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.

不锈钢焊接接头

  2.不锈钢焊接接头的抛光接头的抛光应选择氧化铬绿色抛光膏,抛光轮行走应在一个方向来回运动,用力程度应保持均匀一致。消除打磨痕迹,粗糙度与两侧母材尽量保持一致。

  3.不锈钢焊接接头的酸洗及钝化处理不锈钢焊后,焊缝须进行酸洗、钝化处理。酸洗的目的是去除焊缝及热影响区表面的氧化皮,钝化的目的应使酸洗的表面或抛光表面重新形成一层无色的致密氧化膜,起耐腐蚀作用。常用的酸洗方法有两种:酸液酸洗和酸膏酸洗。酸液酸洗又分为浸洗和刷洗。浸洗法适较小部件,将部件在酸洗槽中浸泡25~45min,取出后用清水冲净。刷洗法适用于大型部件用于,用刷子或拖布反复刷洗焊接接头到呈白亮后,用清水冲洗。
