在大型修建中，為了抵達好的通風效果，一般會采納一些通風辦法，一般還會加設一些通風管道，來完結通風換氣的功用，而抵達這一意圖，咱們是通過螺旋風管來完結的，因此螺旋風管得到了很廣泛的運用。

In large-scale construction, in order to achieve good ventilation effects, some ventilation methods are generally adopted, and some ventilation pipes are usually added to complete the ventilation function. To achieve this goal, we use spiral air ducts, so spiral air ducts have been widely used.

雖然螺旋風管具有許多利益，但是，它大多數(shù)狀況下是露出于室外，因此會遭到風吹雨淋，以及日曬，這些要素會侵蝕或許腐蝕螺旋風管，因此要求它具有防腐功用，由此而發(fā)生的產品有鍍鋅螺旋風管、不銹鋼螺旋風管以及復合螺旋風管，這三種風管具有耐腐蝕性。

Although spiral air ducts have many benefits, in most cases they are exposed outdoors and can be exposed to wind, rain, and sunlight, which can corrode or corrode the spiral air ducts. Therefore, it is required that they have anti-corrosion function. The resulting products include galvanized spiral air ducts, stainless steel spiral air ducts, and composite spiral air ducts, all of which have corrosion resistance.

螺旋風管的效果，除了上面講到的通風換氣外，還能夠進行排氣，或許用來運送一些泡沫塑料等輕質資料。關于不銹鋼焊接收，則又是另一領域，下面來談談這方面。

In addition to the ventilation mentioned above, the spiral air duct can also be used for exhaust, perhaps to transport some light materials such as foam plastics. Regarding stainless steel welding, it is another field. Let's talk about this aspect below.

不銹鋼風管在進行組裝時，能夠通過焊接來完結，這種辦法的本錢較低，且可調性和習慣性高，所以許多人都在運用。

Stainless steel ducts can be assembled by welding, which is a low-cost, adjustable, and habitual method that many people use.

不銹鋼焊接收的焊接技能，也不是現(xiàn)在才呈現(xiàn)的，在公元三千多年前呈現(xiàn)了，僅僅現(xiàn)在愈加成熟和完善。它的焊接，是通過加熱或許加壓，或許兩種一同運用，焊合接縫，然后組裝在一同。能完結不銹鋼中原子間的結合，完結性聯(lián)接。在焊接進程中，一般會用到焊絲，對焊絲的要求是要與不銹鋼的成分堅持共同，這樣能夠確保全體共同性，焊劑則運用氧化性較小的熔煉型或燒結型焊劑，避免損壞合金元素。

The welding skills required for stainless steel welding are not just emerging today. They were introduced over 3000 years ago, but are now becoming more mature and perfected. Its welding is achieved by heating, applying pressure, or using both methods together, welding the joints, and then assembling them together. It can complete the bonding between atoms in stainless steel and complete the bonding. In the welding process, welding wire is generally used, and the requirement for welding wire is to adhere to the same composition as stainless steel, which can ensure overall commonality. The welding flux should use melting or sintering type with lower oxidation to avoid damaging alloy elements.
