A properly made brazed joint (like a welded joint) will in many cases be as strong or stronger than the metals being joined. Second, the joint is made at relatively low temperatures, ranging from about 1150°F to 1600°F (620°C to 870°C). Is brazing better than welding?
NettetThe joints made with welding will be just as strong as the base metals and often even stronger than its base metals. On the other hand, in brazing, the joints are usually … Nettet24. jan. 2024 · 4. Choose a heat source. You can use a soldering iron for joining aluminum wire, but other jobs will require the use of a torch. Typically, a low-temperature torch is used, with a flame tip that reaches 600 to 800ºF (315–425ºC). If torch use is not feasible in your work space, try a 150 watt soldering iron. 5.
