All of the above makes sense except.
Can you solder aluminum ac lines.
Applying the aluminum solder flux.
You can use a soldering iron for joining aluminum wire but other jobs will require the use of a torch.
1 the joints are too weak.
Although these aluminum parts are of differing thicknesses super alloy 5 bonds the metals quickly and easily.
Sure it won t be as easy as soldering say copper or even steel.
Due to the high melting point of these soldering brazing compounds the lines must be purged with inert gases such as nitrogen to prevent oxides forming in the tubing.
20 how to braze aluminum a c lines with weld strength.
This video will explain to you in details how to silver solder braze copper the correct way so you can do it yourself and not have to pay an expensive plum.
After you clean the aluminum metal you should apply the flux carefully along the places you opt to join using either a tiny metal tool or a rod of the solder.
Because of the higher percentage of silver the temperature you ll need to melt this solder is more akin to a brazing temperature so you can think of silver soldering as being on the line between soldering and brazing.
If jointing tubing can be accomplished at lower temperatures the need for high heat and nitrogen purging can be eliminated.
And 2 it can t handle the stresses and vibration which a c lines experience.
The problems with plumbing solder are.
The refrigerant flowing in the inlet line is under extremely high pressure and the slightest imperfection in the soldered joint will allow the freon to escape into the environment.
As the hvac industry uses more aluminum components manufacturers need to join these parts such as evaporator and condenser coils to secondary copper lines or assemblies.
Silver soldering the copper lines to an air conditioner s condenser unit is not rocket science but it does require attention to detail.
Stay brite 8 however does a fantastic job and it also begins to flow at an extremely low temperature.
In brazing or soldering joint design and brazing soldering consumables become key elements for joint integrity.
In case you realize the aluminum pieces are not fitting together smoothly try making the joined places smooth via bending or sanding.
Typically a low temperature torch is used with a flame tip that reaches 600 to 800ºf 315 425ºc.
If torch use is not feasible in your work space try a 150 watt soldering iron.
2 pieces of aluminum air conditioning duct are brazed with super alloy 5 aluminum repair kit and an oxyacetylene torch.
But if you familiarize yourself with the key points of aluminum soldering as are spelled out in the article then you will learn how to effectively solder.
