Can You Solder Aluminum Ac Lines

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.

Can you solder aluminum ac lines.

If torch use is not feasible in your work space try a 150 watt soldering iron. Using silver solder at this percentage is known as a hard solder. 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. Applying the aluminum solder flux.

Silver soldering the copper lines to an air conditioner s condenser unit is not rocket science but it does require attention to detail. 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. 20 how to braze aluminum a c lines with weld strength. In brazing or soldering joint design and brazing soldering consumables become key elements for joint integrity.

2 pieces of aluminum air conditioning duct are brazed with super alloy 5 aluminum repair kit and an oxyacetylene torch. Sure it won t be as easy as soldering say copper or even steel. The problems with plumbing solder are. You can use a soldering iron for joining aluminum wire but other jobs will require the use of a torch.

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. Sure it won t be as easy as soldering say copper or even steel. And 2 it can t handle the stresses and vibration which a c lines experience. 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.

All of the above makes sense except. Although these aluminum parts are of differing thicknesses super alloy 5 bonds the metals quickly and easily. 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. If jointing tubing can be accomplished at lower temperatures the need for high heat and nitrogen purging can be eliminated.

In case you realize the aluminum pieces are not fitting together smoothly try making the joined places smooth via bending or sanding. 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. You ll find out that you can solder aluminum.
