How to weld the refrigerator aluminum tube?
With the wind can weld the welding of aluminum
Flame welding of aluminium tube for refrigerator1, if the operation of basic skills more solid, with 4047 of aluminum silicon welding wire with 201 of welding powder welding, this melting point is high, suitable for master use2, if it is a surname novice, with copper and aluminum wire using low melting point welding, welding can refer to special "video - how ALCU-Q303 welding of copper aluminum pipe joint"
Flame brazing of aluminium tube for refrigerator.Because the refrigerator aluminum tubes are relatively small, relatively thin, and more used for copper tube, aluminum pipe or aluminum pipe copper pipe welding, of course, there are aluminum pipe, aluminum pipe welding. From the above three situations, can be divided into the following welding methods1, if it is aluminum brass or brass tubes connected, can choose Wei Odin copper aluminium welding rod flame brazing welding, the welding work at the melting point of 480 degrees, is cored electrode without the use of complex welding powder.2, if it is connected to the aluminum tubes, aluminum welding can be used WEWELDING Q303, with no need to use liquefied petroleum gas spray welding powder, heating WE53 special welding parts to 500 degrees, and then use the wire in welding parts with a wire tip forming flame burn slightly. Can also use ordinary ER4047 aluminum wire with aluminum powder to WE53-F welding, the welding cost is relatively low, but the technique requirements are relatively high. For expert use.
