手工焊接、金屬極氣體保護焊和鎢極惰性氣體保護焊是焊接不銹鋼通風管道加工的常用方法。手工焊接應用廣泛，操作簡單，主要由人調節。焊縫填充材料為電焊條。幾乎所有的材料都可以手工焊接，即使在室外也可以，所以適應性很好。一般焊接采用DC電。

　　Manual welding, metal inert gas welding, and tungsten inert gas welding are commonly used methods for welding stainless steel ventilation ducts. Manual welding is widely used, easy to operate, and mainly adjusted by humans. The filler material for the weld seam is welding electrode. Almost all materials can be manually welded, even outdoors, so they have good adaptability. Generally, DC electricity is used for welding.

　　焊條可以是鈦焊條，也可以是閉合的。鈦焊條易于焊接，焊縫美觀，焊渣易于去除。但缺點是如果長時間不使用，必須重新烘烤，防止水分堆積。

　　The welding rod can be a titanium welding rod or a closed one. Titanium welding rods are easy to weld, with beautiful welds and easy removal of welding slag. But the disadvantage is that if not used for a long time, it must be re baked to prevent moisture accumulation.

　　不銹鋼螺旋風管的金屬極氣保護焊是一種氣體保護焊，也是一種電弧焊，焊條在保護氣體下通過電弧熔化。金屬極氣保護焊可用于鋼、非合金鋼、低合金鋼、高合金等材料，應用廣泛。

　　Metal electrode gas shielded welding of stainless steel spiral ducts is a type of gas shielded welding and arc welding, in which the welding rod is melted by an arc under shielding gas. Metal electrode gas shielded welding can be used for materials such as steel, non alloy steel, low-alloy steel, and high alloy, and is widely used.

　　但是有一點，它的保護氣體必須是活性氣體，如二氧化碳或混合氣體。其缺點是如果焊接在室外，不銹鋼螺旋風管不能受潮，否則會影響保護氣體的保護效果。

　　But one thing, its protective gas must be an active gas, such as carbon dioxide or a mixture of gases. The disadvantage is that if welded outdoors, the stainless steel spiral air duct cannot be dampened, otherwise it will affect the protective effect of the protective gas.

　　鎢極惰性氣體保護焊接電弧產生于鎢焊絲和工件之間，因此要求保護氣體為純氬氣，焊絲無電，因此可以手動送入，也可以機器送入，有時也可以不送入。那么它是用DC還是交流電，就看焊接材料了。

　　The tungsten inert gas shielded welding arc is generated between the tungsten welding wire and the workpiece, so pure argon gas is required as the shielding gas. The welding wire has no electricity, so it can be manually fed, machine fed, or sometimes not fed. So whether it uses DC or AC depends on the welding material.

　　鎢極惰性氣體保護焊主要用于焊接薄、中厚工件，材料范圍廣，包括合金鋼、鋁、鎂、銅、灰鑄鐵、鎳、銀、鈦、鉛等。

　　Tungsten inert gas shielded welding is mainly used for welding thin and medium thick workpieces, with a wide range of materials including alloy steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium, lead, etc.
