1、不銹鋼風管的電焊焊接，能用非熔融極氬弧焊機；當板才的薄厚超過1.2毫米時，可選用直流電焊機反極法開展電焊焊接，但不可選用氧乙氣割電焊焊接。焊絲或焊條材料應與對接焊縫同樣，沖擊韌性不可小于對接焊縫。

1. The welding of stainless steel ducts can be carried out using a non melting electrode argon arc welding machine; When the thickness of the board exceeds 1.2 millimeters, a direct current welding machine with reverse polarity can be used for electric welding, but oxygen and ethylene gas cutting electric welding cannot be used. The welding wire or electrode material should be the same as the butt weld, and the impact toughness should not be less than that of the butt weld.

2、電焊焊接前，應將焊接地區(qū)的植物油脂、廢棄物清除整潔，以避免 焊接出現(xiàn)出氣孔、沙孔。清理能用車用汽油等開展。

2. Before welding, the vegetable oil and waste in the welding area should be cleaned up to avoid air and sand holes during welding. Clean up and use gasoline for vehicles.

3、用電弧焊接電焊焊接不銹鋼板時，應在焊接的兩邊表面涂上灰?guī)r粉，避免 濺出金屬材料黏附在板才的表面損害板才。

3. When welding stainless steel plates with electric arc welding, limestone powder should be coated on both sides of the welding surface to avoid splashing metal material adhering to the surface of the plate and damaging it.

4、電焊焊接后，應留意清除焊接處的爐渣，并且用不繡鋼刷或銅線刷一下出金屬質(zhì)感，再用酸洗膏開展磷化處理，后用開水清理整潔。

4. After welding, attention should be paid to removing slag from the welding area, and using a stainless steel brush or copper wire to brush out the metallic texture. Then, phosphating treatment should be carried out with acid pickling paste, and finally cleaned with boiling water.

5、不銹鋼的焊接風管應免去在風管焊接以及邊沿處開孔。

5. Stainless steel welded air ducts should be exempt from opening holes at the welding and edges of the ducts.

不銹鋼風管異型管：除接管之外的管的統(tǒng)稱，用低溫等離子機激光切割，單機版轆邊。短管：同接管表明方式一致A*B*C(A、B為支管，C為長短)，短小編長不確定，依據(jù)具體必須而定，eg：500*200*600即支管為500*200長短為600；標準(除基礎標準外)：長短。三通：表明方式：A*D～B*D～C*D,(A、B、C為控制面板，D為檔板),三通分碟形三通和T形三通，分碟形三通的標準(除基礎標準外)：兩側(cè)的R值與樣子；T形三通的標準(除基礎標準外)：R值，長短(測算方法=右邊支管+R+100)。

Stainless steel air duct special-shaped pipe: a general term for pipes other than connecting pipes, laser cut with low-temperature plasma machine, and rolled edge with single machine version. Short pipe: The same indication method as the connecting pipe is A * B * C (A and B are branch pipes, C is the length). The length of the short pipe is uncertain and depends on specific requirements. eg: 500 * 200 * 600 means that the branch pipe is 500 * 200 and the length is 600; Standards (excluding basic standards): length. Three way: indication method: A * D~B * D~C * D, (A, B, C are control panels, D is a baffle), three-way is divided into disc-shaped three-way and T-shaped three-way, the standard for disc-shaped three-way (except for the basic standard): R value and appearance on both sides; The standard for T-shaped tees (excluding basic standards): R value, length (measurement method=right branch pipe+R+100).
