Stainless steel welding air valve factory will introduce some new professional knowledge in detail, so that everyone can have a deeper understanding of stainless steel air duct. The next key interpretation is the welding type of stainless steel pipe. The common welding methods of stainless steel air duct are manual welding, commonly known as MMA, metal material electrode gas shielded welding and tungsten inert gas shielded welding. Metal material electrode gas shielded welding is commonly known as MIG / MAG, and tungsten inert gas shielded welding is commonly known as TIG.

方式 一：不銹鋼螺旋風(fēng)管廠手工制作焊應(yīng)用十分廣泛，且實際操作非常容易，主要是靠人開展調(diào)整，焊接添充原材料為不銹鋼焊條。手工制作焊基本上能焊接全部的原材料，即便在戶外也可以，因而它具備非常好的適應(yīng)能力，一般焊接時是選用直流電源。不銹鋼焊條，既能夠 是鈦型焊絲，也可以是緘性的。鈦型焊絲較為非常容易焊接，焊接美觀大方，且焊穿非常容易除去。但缺陷是假如長期無需后再應(yīng)用，那麼務(wù)必再次開展烤制，防止?jié)駳舛逊e。

Method 1: the manual welding of stainless steel spiral air duct factory is widely used, and the actual operation is very easy. It is mainly adjusted by people. The raw material for welding is stainless steel electrode. Manual welding can basically weld all raw materials, even outdoors, so it has very good adaptability. Generally, DC power supply is selected for welding. Stainless steel electrode can be either titanium type welding wire or sealed. Titanium type welding wire is very easy to weld, the welding is beautiful and generous, and the welding penetration is very easy to remove. However, the defect is that if it is not needed for a long time, it must be baked again to prevent moisture accumulation.

方式 二：金屬材料極氣體保護焊它歸屬于氣體保護焊，也是一種電弧焊接，是在維護氣體下，焊絲被電孤溶化。金屬材料極氣體保護焊可用以鋼、非碳素鋼、高合金鋼及其高鋁合金等這種原材料，應(yīng)用很普遍。但有一點，它的維護氣體務(wù)必為特異性氣體，例如二氧化碳或是混和氣體等。

Mode 2: metal material electrode gas shielded welding, which belongs to gas shielded welding and is also an arc welding. The welding wire is melted by electric arc under the maintenance gas. Metal material electrode gas shielded welding can be used as raw materials such as steel, non carbon steel, high alloy steel and its high aluminum alloy. However, its maintenance gas must be specific gas, such as carbon dioxide or mixed gas.

的缺陷是假如在戶外開展焊接，那麼產(chǎn)品工件不可以返潮，不然會危害維護氣體的維護實際效果。方式 三：鎢極惰性氣體保護焊電孤是在鎢電弧焊接絲和產(chǎn)品工件中間造成，因此 規(guī)定維護氣體為純氬氣，且焊條不是感應(yīng)起電的，因此 既能夠 手動式送進，也可以設(shè)備送進，有時候也可以不送進。隨后它到底是應(yīng)用直流電源還是交流電流，則在于焊接原材料。鎢極惰性氣體保護焊主要是用以焊接薄和中等水平薄厚的產(chǎn)品工件，材料的范疇很廣，包含碳素鋼、鋁、鎂、銅、灰鑄鐵、鎳、銀、鈦及其鉛等。

The defect is that if welding is carried out outdoors, the product workpiece cannot return to moisture, otherwise it will endanger the actual maintenance effect of maintenance gas. Mode 3: tungsten inert gas shielded arc welding arc is caused between the tungsten arc welding wire and the product workpiece. Therefore, it is specified that the maintenance gas is pure argon and the electrode is not inductively energized. Therefore, it can be sent manually, equipment or not. Then, whether it applies DC power supply or AC current depends on the welding raw materials. Tungsten inert gas shielded welding is mainly used to weld thin and medium thin and thick product workpieces. There are a wide range of materials, including carbon steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium and lead.
