在大型修建中，为了抵达好的通风效果，一般会采纳一些通风办法，一般还会加设一些通风管道，来完结通风换气的功用，而抵达这一意图，咱们是通过螺旋风管来完结的，因此螺旋风管得到了很广泛的运用。

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.

虽然螺旋风管具有许多利益，但是，它大多数状况下是露出于室外，因此会遭到风吹雨淋，以及日晒，这些要素会侵蚀或许腐蚀螺旋风管，因此要求它具有防腐功用，由此而发生的产品有镀锌螺旋风管、不锈钢螺旋风管以及复合螺旋风管，这三种风管具有耐腐蚀性。

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.

螺旋风管的效果，除了上面讲到的通风换气外，还能够进行排气，或许用来运送一些泡沫塑料等轻质资料。关于不锈钢焊接收，则又是另一领域，下面来谈谈这方面。

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.

不锈钢风管在进行组装时，能够通过焊接来完结，这种办法的本钱较低，且可调性和习惯性高，所以许多人都在运用。

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

不锈钢焊接收的焊接技能，也不是现在才呈现的，在公元三千多年前呈现了，仅仅现在愈加成熟和完善。它的焊接，是通过加热或许加压，或许两种一同运用，焊合接缝，然后组装在一同。能完结不锈钢中原子间的结合，完结性联接。在焊接进程中，一般会用到焊丝，对焊丝的要求是要与不锈钢的成分坚持共同，这样能够确保全体共同性，焊剂则运用氧化性较小的熔炼型或烧结型焊剂，避免损坏合金元素。

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.
