1，手工制做焊接

1. Manual welding

焊接通風風管生產(chǎn)廠家被廣泛運用并且易于操作過程。焊接通風風管耐負壓力主要是由人為要素調(diào)整。焊接添充原料是電極。手工制做焊接大部分可以焊接所有原料，就算在戶外也是如此，因此擁有非常好的適應(yīng)力。一般，DC用于焊接。風管制作加工方案電極可以是鈦電極或密閉性電極。鈦電極易于焊接，焊接別具一格，焊渣易于去除。但是缺點是，倘若長時間不運用它，則須再一次烘烤以防止水分沉積。

Welded ventilation duct manufacturers are widely used and easy to operate. The negative pressure resistance of welded ventilation duct is mainly adjusted by human factors. Welding filler material is electrode. Hand made welding can weld most of all raw materials, even outdoors, so it has very good adaptability. In general, DC is used for welding. The manufacturing and processing scheme of air duct electrode can be titanium electrode or airtight electrode. Titanium electrode is easy to weld, unique welding, and welding slag is easy to remove. However, the disadvantage is that if it is not used for a long time, it must be baked again to prevent moisture deposition.

2，氣金屬復合材料電孤焊接

2. Gas metal composite electric arc welding

技術(shù)共板法蘭風管屬于氣體保護焊，也是一種電孤焊接，是在維護氣體中，電極被電孤熔化。金屬復合材料焊條氣體保護焊可作為鋼，非碳鋼，鐵素體不銹鋼和金相組織不銹鋼板等。但有一點是，其維護氣體須是魅力氣體，例如通風管道安裝廠家二氧化碳或混合氣體。缺點是，倘若在戶外進行焊接，則商品產(chǎn)品工件不易潮濕，工廠通風管道加工要不然會傷害維護氣體的維護預期效果。

The common plate flange air duct of technical specialty belongs to gas shielded welding, which is also an electric arc welding. The electrode is melted by the electric arc in the maintenance gas. Metal composite electrode gas shielded welding can be used as steel, non carbon steel, ferritic stainless steel and metallographic stainless steel plate. However, one thing is that the maintenance gas must be charm gas, such as carbon dioxide or mixed gas of ventilation pipe installation manufacturer. The disadvantage is that if welding is carried out outdoors, the workpiece of commercial products is not easy to be wet, and the processing of factory ventilation pipe will otherwise damage the expected maintenance effect of maintenance gas.

3，鎢極延展性氣體保護焊

3. Tungsten ductile gas shielded welding

在鎢絲和商品正中間會產(chǎn)生電孤，因此務(wù)必純氬氣作為維護氣體，并且不易插電。因此，可以手拉式，工業(yè)設(shè)備方式消息推送，有時還能夠不消息推送。接著運用直流電源或者交流與溝通取決于焊接原料。鎢極延展性氣體保護焊重要用于焊接薄和中等偏上壁厚的商品產(chǎn)品工件，其原料范圍廣泛，包括碳鋼，鋁，鎂，銅，灰鑄鐵，鎳，銀，鈦和鉛。

An electric arc will be generated between the tungsten wire and the commodity, so pure argon must be used as the maintenance gas, and it is not easy to plug in. Therefore, you can push messages by hand, industrial equipment, and sometimes you can not push messages. Then use DC power or AC and communication, depending on the welding material. Tungsten ductile gas shielded welding is important for welding thin and medium upper wall thickness commercial products. It has a wide range of raw materials, including carbon steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium and lead.
