Common Aluminum Tube Welding Method In Industry
Jul 18, 2018

The aluminum pipe is commonly used, but the welding is still not clear enough. Today, I would like to share the welding principle and matters needing attention.

The welding of aluminum tube, also known as aluminum pipe welding, rong, welding is a kind of joint in the form of heat, high temperature or high pressure metal or other thermoplastic materials such as plastic manufacturing process and technology, welding can be divided into three kinds.

1, welding, heat to joint the workpiece to form the partial melting of molten pool, pool and joint after cooling solidification, can melt filling material by adding auxiliary when necessary, it is suitable for all kinds of metal and alloy welding processing, without pressure.

2. Pressure welding -- the welding process must apply pressure to the welding parts, which belongs to the processing of various metal materials and some metal materials.

3. Brazing -- using metal material with lower melting point than the base material as solder, wetting the base material with liquid solder, filling the joint clearance, and diffusing with the base material to realize the link welding parts. Suitable for welding of various materials, also suitable for welding of different metals or different materials.

In general, aluminum pipe welding can be carried out in the following ways

1. Argon arc welding is commonly used. Welding wire is made of 4 series, 5 series and 6 series, which are sold in general hardware stores.

2, low temperature of M51 with M51 -f wire welding in the operation, the working temperature of 179 degrees environment for 1, 2, 3, 4, 6, affinity of welding material is better, more for special strict with deformation control, or under the condition of special thin welding.

Article 3, WE53 low temperature weld for seven series of aluminum alloy welding, welding working temperature at 380-380 degrees, is don't need any auxiliary when welding flux welding, thus preventing some solder residue in the process of welding, and welding strength is very high, can solve 3 series aluminum alloy and casting, welding or die casting.

4. Q303 low temperature aluminum wire welding performance of 1, 2, 3, 4 and 6 series of aluminum alloy welding also reflects some special advantages in small gap welding with poor Angle.
