黃銅管焊接方法

作者:匿名    訪問量:3578    發布時間:2013-09-16

我公司是以生產、銷售、維護黃銅管為一體的公司,近年來公司不斷發展技術力量,創新生產技術手段,生產的產品銷往全國各地,受到客戶的一致好評,今天讓大家了解一下黃銅管的焊接方法:

1、焊接過程中,始終保持火焰蓋住接點,以免空氣進入; 
2、助焊劑會被焊干,水分在100℃會蒸發,助焊劑變成乳白色。 
3、助焊劑在316℃時會起泡。 
4、助焊劑在427℃時成為糊狀 
5、助焊劑在593℃時變成流體,接近銅焊溫度。 
6、含銀35%-40%之焊料在604℃時熔化,在618℃時流動。 
7、注意被焊二工件都要用焊槍加熱。 
8、經火焰顏色可以觀察溫度是否合適,溫度達到銅焊溫度時,火焰出現綠蔭,達到銀焊溫度綠色火焰表示溫度適宜。 
9、銅管和鋼管互相焊接,首先要加熱銅管(因為銅管傳熱快,需要的熱量多)。 
10、銅焊過程,焊槍不要始終停在一點,可作8字形移動。 
11、推薦使用大號焊槍,如此可以用柔和火焰求大熱量而不出現超壓或“吹風”,最好在內部錐形火焰上稍有羽輝 。更多黃銅管知識請登錄:(圖/文www.startamils.com)

Our company is the production, sales, maintenance of brass for the whole company, the development of the company technical force is constantly in recent years, technology innovation and production, products are sold throughout the country, by the customer the consistent high praise, today let everyone know about welding method of brass tube:
1, in the process of welding, always keep the flame cover contact, so as to avoid air entering the;
2, the flux will be welded dry, moisture will evaporate at 100 ℃, flux to become milky white.
3, the flux will bubble at 316 ℃.
4, the flux become mushy at 427 ℃
5, the flux into the fluid at the temperature of 593 ℃, close to the brazing temperature.
6, 35%-40% Ag solder melting at 604 ℃, 618 ℃ flow.
7, pay attention to two by welding workpiece with welding torch heating.
8, the flame color can observe the temperature is appropriate, the temperature at the brazing temperature, the flame temperature reached the green shade, silver brazing flame that suitable temperature.
9, brass and steel pipe welded each other, first of all to the heating tube (because the copper pipe heat quickly, need more calories).
10, the torch brazing process, don't always stop at a point, can make the figure 8 mobile.
11, recommend the use of large welding torch, so can be used for high calorie soft flame without overpressure or "hair", the best in the internal conical flame slightly Yu Hui.
