本刊94年第3期发表 AF-3中温铝焊条一文后,收到许多读者来信,现就有关问题答复如下。一、用该焊条时,使用什么焊炬?最好使用液化气焊炬,因为该焊炬较柔和,温度容易控制,液化气价格比乙炔低。由于乙炔温度高且不好控制,会时常将铝工件焊穿或产生严重变形。如果焊接技术高,也可以使用乙炔焊炬。总之,活焊得好不好与焊接技术和焊接用工装关系很大。 After the publication of AF-3 Mid-temperature Aluminum Welding Rod Article in 1994, we received many letters from our readers. The answers to the relevant questions are as follows. First, with the electrode, the use of what torch? The best use of liquefied gas torch, because the welding torch softer, easy to control the temperature, liquefied gas prices lower than acetylene. Due to the high temperature of acetylene and poor control, will often weld aluminum parts or produce serious deformation. If the welding technology is high, you can also use acetylene torch. In short, the welding is not good and welding technology and welding tooling a great relationship.
