ALUMINUM WELDING

摘要

The use of aluminum tooling is becoming more common. Choosing the right wire and the right welding technique will produce the most effective mold repair. Once viewed strictly as a prototype tooling material, aluminum is gaining ground as an option for production molds. In considering this option, it is important to first look at the differences between steel and aluminum, and then determine how best to take advantage of aluminum's increased thermal conductivity without degradation of part quality. It's also important to consider issues related to mold repair. Producing a quality part from an aluminum mold is relatively easy, but repairing these molds can pose challenges. To ensure successful repair of an aluminum mold requires an understanding of the differences between steel and aluminum, and the aluminum alloy options, as well as knowledge about welding wire and proper welding techniques.
