How To Weld Aluminum Pipe Together

You would heat it poke it then allow the puddled metal to cool off as one linked piece. A good way to make X-ray-quality pipe welds in aluminum is to use an extended-land joint geometry see Figure 4.

Touch the welding rod to the material so as to just leave enough aluminum on the joint.

How to weld aluminum pipe together. Get the torch lit and have your welding rod ready. This is the only way to create a clean weld. The trick to a lasting weld on aluminum tubing is all in the technique.

All this can be found at your. Another method many use to successfully weld aluminum to steel is dip coating also commonly referred to as hot dip aluminizing. But if you are welding thicker walled pipe then you are going to bevel a V or U butt joint.

For example if you were welding two pieces of aluminum together you would take your rod straight down the line that runs between the two separate pieces. Very simply you take two pipes and put them together and now you have a butt joint to weld. A torch with more of a pin point would do better.

A second more involved method is the TIG welding method where a different type of welder is used along with aluminum rods that are melted to tack the work piece together. Aluminum will start to melt at 1200deg Fahrenheit but the brazing rod will melt at around 700deg so we want to get the aluminum hot enough to melt the rod without melting the tubing. Getting the tubing hot enough may take 4 to 5 minutes.

In either case if you have a propane torch and brazing rods you can weld aluminum. Lift the rod and move the torch forward or back depending on which way you are welding and repeat the rod touch to the joint. However aluminum is relatively soft so the weld preparation can be machined using a wood router with a router bit.

Clean your aluminum remove any oxide and file the edges that will be joined Avoid pulling while weldinginstead push at a 10 to 15 degree angle Use multiple pass straight beads to improve the overall appearance of the weld and help to avoid defects Use a heat sink which will absorb extra heat and allow you to weld slower. In this type of joint machining is necessary for weld preparation which is a disadvantage. Clamp up the tubing and start heating the aluminum with a propane torch.

To weld aluminum clamp the aluminum pieces together tightly and use a propane torch to preheat them to a temperature between 300F and 400F. This simply means that prior to welding the steel and aluminum together the steel is first coated in aluminum. When welding aluminum pipe it is a good idea to begin with clean metal ends where you intend to weld the pipe together.

The most common type of joint used for welding together pipe is a butt joint. Produce arc-welded joints between aluminum and steel pipelines Coat the steel prior to welding. With aluminum pipe this is not possible to do which means the aluminum pipe to be welded must fit together tightly with no gaps.

Then set the amperage of your welder aim at the aluminum pieces and press the button on the torch. Step 2 Melt the metal rod or wire against the two pieces of metal you are attempting to join until they have pooled together.
