I, Weld defectus: immaculatam ferro FlangeWeld defectus sunt gravi, si est utor manual mechanica molere curatio modum facere, tunc molere marcas, unde inaequaliter superficiem, afficit speciem;
II, Polising et Polising passivation non uniformis:Pickling Passivation curatio post manual molere et politura, pro magna workpiece area, difficile ad consequi uniformis curatio effectus, potest non specimen uniformis superficiem. Etiam habet incommodum homo, hora costs, forcia costs sunt altior;
III, scalpit difficile ad removendum:overall pickling passivation, in the presence of corrosive medium will occur chemical corrosion or electrochemical corrosion and rust, also can not remove due to scratches, welding splash and adhere to the surface of stainless steel carbon steel, splash and other impurities;

Ut solvere problema estimmaculatam ferro FlangeProcessing?
I, Select Blanking:Post completionem, in proximum, aliud immaculatam ferro workpiece secundum dispensando requisitis in correspondentes processus;
II, inclinans ad primam in magnitudine,according to the drawing stainless 304 seamless steel tube material thickness to determine the bending with knives and knife trough, avoid products with cutting tool collision caused deformation is the key to the selection mode (in the same products, may use different models of upper die) Et delectu inferioris mori secundum crassitiem tabula.
III, ut welding firmum est:Ad quod Welding workpiece convexa punctum, potest facere bumps in fronte de electrica welding et laminam uniformis contactus, ut consistent utriusque puncto ad calorem, welding situ potest determinari simul, in opus ad coarctare potest simul, quod adaequatum est in tempore, quod est determinari in tempore, quod adaequatum Preloading tempus, tenens tempus, maintaining et quietem tempus, ut workpiece potest macula welding firmum.
