表現(xiàn)一：不銹鋼螺旋風(fēng)管表面出現(xiàn)一些缺點難題，例如擦毛、污跡等。

Performance 1: There are some defects and problems on the surface of the stainless steel spiral air duct, such as scuffing and stains.

表面二：在電弧焊接電焊焊接表面，其顏色是呈灰黑色的，或是是有黃點或黑色斑。

Surface 2: The color of the arc welding surface is gray-black, or there are yellow spots or black spots.

表面三：不銹鋼螺旋風(fēng)管的一部分出現(xiàn)生銹。

Surface 3: part of the stainless steel spiral air duct is rusted.

這三種狀況，其腐蝕水平是越來越嚴(yán)重，一旦出現(xiàn)該難題的話，則會減少其抗腐蝕工作能力，減少其使用期限。針對排風(fēng)系統(tǒng)而言，則會減少其氣密性檢測，因此它的危害是不可小覷的。

The corrosion level of these three conditions is becoming more and more serious. Once this problem occurs, its corrosion resistance will be reduced and its service life will be reduced. For the exhaust system, it will reduce its air tightness detection, so its harm cannot be underestimated.

不銹鋼螺旋風(fēng)管出現(xiàn)腐蝕，其緣故，一般有以下這類緣故：

Corrosion of stainless steel spiral air duct is generally caused by the following reasons:

(1)不銹鋼螺旋風(fēng)管所應(yīng)用的板材，其切料或生產(chǎn)加工具體方法不善。

(1) The specific method of cutting or production and processing of the plate used for stainless steel spiral air duct is not good.

(2)不銹鋼螺旋風(fēng)管在生產(chǎn)加工生產(chǎn)制造全部全過程中，就出現(xiàn)了腐蝕情況，但并沒有立刻開展解決。

(2) Corrosion occurred in the whole process of production, processing and manufacturing of stainless steel spiral air duct, but it was not solved immediately.

(3)不銹鋼螺旋風(fēng)管的焊接方法沒有挑選適度，也就是焊接方法不善。

(3) The welding method of stainless steel spiral air duct is not properly selected, that is, the welding method is not good.

(4)不銹鋼螺旋風(fēng)管電弧激光焊接電弧焊接電焊焊接好之后，沒有立刻開展和，就開展之后解決了。

(4) Arc laser welding of stainless steel spiral air duct Arc welding After the electric welding was completed, the elimination and removal were not carried out immediately, and then the problem was solved.
