How To Weld Aluminum Pipe Together. This is the only way to create a clean weld. All this can be found at your.
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. Very simply you take two pipes and put them together and now you have a butt joint to weld. 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.
Touch the welding rod to the material so as to just leave enough aluminum on the joint.
But if you are welding thicker walled pipe then you are going to bevel a V or U butt joint. Clamp up the tubing and start heating the aluminum with a propane torch. 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. Step 2 Melt the metal rod or wire against the two pieces of metal you are attempting to join until they have pooled together.
