現在濟南不銹鋼雕塑在城市建設中起著至關重要的作用，而由于經常放置在室外，所以難免會有一些損傷。Ji'nan stainless steel sculpture is now playing a vital role in urban construction, and often placed in the outdoor, it will inevitably have some damage.    

1.焊接引弧斑痕：焊工在金屬表面引弧時，會造成表面粗糙缺陷。濟南不銹鋼雕塑保護膜受損，留下潛在的腐蝕源。焊工應在已經焊好的焊道上或在焊縫接頭的側邊引弧。然后將引弧痕跡熔入焊縫中。 Welding arc spot welder: on the surface of the metal arc, will cause surface defects. Ji'nan stainless steel sculpture protective film damage, leaving a potential source of corrosion. The welder shall draw the arc on the weld or on the side of the weld joint. Then the arc trace is melted into the weld.   

2.銹斑：制作前或制作過程中有時會看到不銹鋼產品或設備上生銹，這說明表面受到嚴重污染。設備投入使用前必須把銹清除掉，徹底清理過的表面應通過鐵試驗和/或水試驗進行檢驗。 Rust: pre production or production process sometimes see rust stainless steel products or equipment, the surface is seriously polluted. The rust must be removed before the equipment is put into use. The thoroughly cleaned surfaces shall be inspected by iron and / or water tests.   

3.焊接缺陷：焊接缺陷如：咬邊、未焊透、密集氣孔和裂紋不僅降低接頭的牢固性，而且還會成為縫隙腐蝕的腐蝕源。改善這種結果進行清理操作時，它們還會夾帶固體顆粒。濟南不銹鋼雕塑這些缺陷可通過重新焊接或修磨后重焊進行修補。  Welding defects such as undercut, lack of penetration, dense pores and cracks can not only reduce the bonding strength, but also become the source of crevice corrosion. When the results are improved, they also carry solid particles. Ji'nan stainless steel sculpture these defects can be repaired by re welding or grinding. 

4.劃痕：為了防止工藝潤滑劑或生成物和/或污物積留，必須對劃痕和其它粗糙表面進行機械清理（如干噴砂，磨料用玻璃珠)。Scratch: in order to prevent the production of lubricant and / or dirt and / or dirt from the process, it is necessary to perform mechanical cleaning of scratches and other rough surfaces (such as dry blasting, abrasive glass beads).
   
5.油和油脂：有機物質如：油，油脂甚至指印都會成為局部腐蝕的腐蝕源。由于這些物質能起屏障作用，它們會影響化學和電化學清理效果，因而必須徹底清理掉。Oil and grease: organic substances such as oil, grease and even fingerprints will become the source of local corrosion corrosion. Because these substances can act as a barrier, they can affect the chemical and electrochemical cleaning effects, so they must be completely cleaned up.    

6.油漆、粉筆和標記筆印：這些污染物的影響與油和油脂的影響相似。建議用干凈的刷子和干凈的水或堿性清洗劑進行洗滌，也可以使用高壓水或蒸汽沖洗。 Paint, chalk and marker pen: the effects of these contaminants are similar to those of oil and grease. It is recommended to use a clean brush and clean water or alkaline cleaning agent for washing, can also use high-pressure water or steam washing. 

7.焊劑：利用焊劑進行焊接的工藝有手工焊，帶焊劑芯電弧焊和埋弧焊，這些焊接工藝都會在表面留下細小的焊劑顆粒，普通的清理方法無法將它們清除掉。這此濟南不銹鋼雕塑顆粒將是縫隙腐蝕的腐蝕源，必須采用機械清理方法去除這些殘留焊劑。Flux: welding process with manual welding with flux, with flux cored arc welding and submerged arc welding, the welding flux will leave tiny particles on the surface, the ordinary cleaning method cannot be rid of. The stainless steel sculpture particles in Ji'nan will be the source of crevice corrosion, which must be removed by mechanical cleaning.    

8.熱回火色和其它氧化層：熱回火色是由于在高溫或長時間在較高度下停留所致。當出現任何一種這類氧化層時，金屬表面的鉻含量都會降低，造成這些區域的耐腐蝕性降低。在這種情況下，不僅要消除熱回火色和其它氧化層，還應對它們下面的貧鉻金屬層進行清理。Back fire heat and other oxidation layer: back fire heat is due to the high temperature or long time at a height of stay by. When any of these oxides are present, the chromium content of the surface of the metal will be reduced, resulting in the reduction of corrosion resistance of these areas. In this case, not only to eliminate the back fire heat and other metal oxide layer, the chromium depleted layer also deal with them the following cleaning.    

9.粉塵：制作經常是在有粉塵的場地進行，空氣中常帶有許多粉塵，它們不斷地落在設備表面。它們可以用水或堿性溶液去除掉。不過，有附著力的塵垢需要高壓水或蒸氣進行清理。 Dust: the production is often in the dust of the site, often with a lot of dust in the air, they continue to fall on the surface of the equipment. They can be removed by water or alkaline solution. However, the dust adhesion need high pressure water or steam cleaning.   

10.殘余粘合劑：撕掉膠帶和保護紙時，粘合劑總有一部分殘留在不銹鋼表面。如果粘全劑還沒硬，可以用有機熔劑去除。但是，當濟南不銹鋼雕塑曝露在光或空氣中時，粘全劑變硬，形成縫隙腐蝕的腐蝕源。Residual adhesive: when the tape is removed and the paper is protected, some of the adhesive remains on the surface of the stainless steel. If the adhesive agent is not hard, can be removed with organic flux. However, when the Ji'nan stainless steel sculpture is exposed to light or air, the adhesive hardens and forms a crevice corrosion source.
