How To Tig Weld Aluminum Pipe. Electron beam welding has a very precise heat affected. Use a heat sink, which will absorb extra heat and allow you to weld slower;
And do yourself a favor and get some 4047 rod for castings where porosity rares its ugly head. 3.block off the ends to trap the gas; Tig welding produces high quality and aesthetically pleasing welds.
Aluminum's high thermal conductivity means that the weld pool is larger than it is in steel.
Electron beam welding has a very precise heat affected. However, it is possible to tig weld aluminum with direct current (also called “dc”). When tig welding aluminum, alternating current (or “ac”) is almost always used. The combination of en weld polarity and faster tig weld speeds, enables the lowest possible weld joules for any metals, and this also applies when ac balance wave welds on made on aluminum weld joints.
