Aluminum Welding - welcome to the welder and Gentlemen. Do you really love your Laas tool? sure you will answer "YES". So, how do you do it? This page will present five interesting tips for caring for your welding machine to be more durable, and good. So that your work will not stop because of your machine breaking down while working.
Here are 5 tips aluminum engine maintenance for you:
1. Preheating: Preheating of aluminum workpiece can help avoid weld cracking. Preheating temperature should not exceed 230 F-use temperature indicator that is not too hot. In addition, placing tack welds at the beginning and end of the area to be welded will assist in efforts to pre-heating. Welder must also heat up a thick piece of aluminum when welding to thin slice, if the cold lapping occurs, try using a walk-on and run-off tab.
2. Pressing technique: With aluminum, pushed the gun away from the weld puddle rather than pulling it will produce a better cleaning action, reduced weld contamination, and improved shielding gas coverage.
3. Travel speed: Aluminium welding needs to be done "hot and fast." Unlike steel, high thermal conductivity of aluminum to determine the use of heat and electricity better voltage regulation and high-weld travel speed. If the travel speed is too slow, the welder burnthrough excessive risks, particularly in thin-gage aluminum sheet.
4. Shielding gas: Argon, because of a good cleaning action and penetration profiles, shielding gas is the most commonly used when welding aluminum. Welding 5xxx-series aluminum alloy, a mixture of argon shielding gas combines with helium - a maximum of 75 percent helium - will minimize the formation of magnesium oxide.
5. Welding wire: Select aluminum filler wire which has a melting temperature similar to the base material. The more operators can narrow down the distance molten metal, it's easier to weld alloys. Get a wire that 3/64- 1/16- inch or diameter. The larger the wire diameter, the easier it will feed. For welding thin-gage material, a 0.035 inch diameter wire combined with pulsed-welding procedures on low-speed wire-feed -. 100 to 300 in / min - works well.
That information can we present to you the aluminum welder. May be useful and can help you. Follow the update information from us in centralwelding.blogspot.com. We always gives an interesting review of the welding for you.

Believe it or not this blog related to motorcycle frames welding, and I'm glad that I read the entire content of it. Such a well done post!
