分段的紫銅管如何進行焊接

作者:匿名    訪問量:2573    發布時間:2013-09-15

我公司是以生產、銷售、維護紫銅管為一體的公司,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分段的紫銅管如何進行焊接。
生產水內冷變壓器后剩下來的紫銅管有時候我們不知道咋辦,丟了可以。其實這些紫銅管可以用氣焊法把它們進行連接在使用。
      因為銅管是用在水內冷變壓器上面的,所以,焊接接頭上面的質量有一定的要求,不能夠有水漏出來,接頭的地方要沒有毛刺,管里面不能夠有熔塌、有焊瘤還有堵塞的情況,不然可能會造成變壓器短路,讓管里面的水可以自由流通,不讓要線圈的溫度過高??梢杂勉y合金焊絲來填充,讓焊接接頭質量更可靠。

      焊接的方法首先是可以把兩根銅管的兩端鋸平了,在用夾具夾住一根銅管,用氧乙炔焰來加熱,把管的端口擴大,另外一根插到里面,再用夾具固定好。在用石棉繩拉緊了,不讓熱量散開來。使用剩下來的氧化焰,讓焰心和工件保持一定的距離,焊絲和焊炬要垂直。在焊絲末端加上焊粉,把它撒到熔池中還有焊縫邊緣上面。溶劑是用百分之七十到八十的硼砂,還有百分之二十到三十的鹽制成的。當焊接的地方溫度到餓了550到600度的時候,在用冷水把溫度降下來,細化晶粒,讓接頭有非常好的塑性。最后就是把焊接的地方用銼刀銼平,用金鋼砂紙磨光。(圖/文www.startamils.com)

Our company is the production, sales, maintenance of copper 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, let everyone know about copper pipe segment to welding.
Copper production water cooled transformer remaining sometimes we don't know what to do, can be lost. In fact, the copper pipe welding method can be used to their connections in use.
Because the brass is used in water cooled transformer above, therefore, have certain requirements for the quality of welded joints above, can not be leaking out, joint place without burr, the inside of the tube not to collapse, there is overlap and blocked, otherwise may cause short-circuit, let inside the tube water can flow freely, don't let to coil temperature is too high. Can use silver alloy wire filling welding joint quality is more reliable, let.
Welding method is first can make both ends of two copper saw flat, in the grip a copper pipe clamp, with oxygen acetylene flame heating, the pipe port expansion, a root cutting to the inside, then the clamping fixed. In the asbestos rope, don't let the heat spread. The use of the rest of the oxidizing flame, let the flame and the workpiece to maintain a certain distance, welding wire and welding torch to the vertical. In the wire end plus solder powder, put it onto the weld pool and weld edge. The solvent is seventy percent to eighty of borax, and twenty percent to thirty of the salt is prepared. When the welding temperature to the hungry at 550 to 600 degrees, use cold water to stop, grain refinement, make joint plastic very good. The last is to weld local file flat, polished with emery.
