Welding Aluminium Profiles. Then set the amperage of your welder aim at the aluminum. It should be noted that with DC supplies that there is a marked polarity effect.
Al-Men Oy is a Finnish company whose main working field is processing of extruded aluminium profiles. Aluminium extrusion is a forming process used to produce profiles and accounts for almost a half of aluminium production. Argon due to its good cleaning action and penetration profile is the most common shielding gas used when welding aluminum.
About 80 of these are Aluminum Profiles.
Grenzebach friction stir welding technology allows the creation of welding seams with outstanding external and internal properties. Welding 5XXX-series aluminum alloys a shielding-gas mixture combining argon with helium - 75 percent helium maximum - will minimize the formation of magnesium oxide. Tungsten Inert Gas TIG welding also known as Gas Tungsten Arc Welding GTAW is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. RAESA has a wide experience in aluminium welding.
