Aluminum welding is one of the easiest welding methods available today. Aluminum is one of the easiest metals to weld on because it melts at a relatively low temperature and it does not crack after solidifying. It is done based on the type of aluminum that will be used.
Commercial grade aluminum has 99% purity and it only contains a small amount of other elements such as manganese or magnesium. These types of aluminum are easier to weld. Whereas the type of aluminum that contains elements like copper or lead are more difficult to weld and sometimes, it results to cracking while welding.
This method comprises of the TIG and the MIG welding aside from other customary methods like resistance welding, gas, plasma, and covered electrodes welding. TIG welding is used if good surfaced finishes are needed and when there are non-accessible parts that should be weld. This method is also preferred when it comes to repairing castings. MIG technique is used for welding thicker types of aluminum that needs to be done in a fast rate. It also produces long, continuous welds. This method requires a lower heat input that produces less damage in the welding zone.
One of the latest aluminum welding approach makes use of a pulse arc welding that is combined with the MIG method. This technique produces better results than other traditional methods. It also provides better control of the molten pool in case they are using thin materials. It makes the arc more stable with less spatters and it also alleviates the risk of welding imperfections.
To produce better quality of aluminum welding, the aluminum that will be used should be clean. Aluminum is one of the materials that are highly obnoxious to airborne contaminants therefore; extra measures must be done to clean it before the actual welding process.
It is also preferred that in welding aluminum, the process should be done as fast as possible because aluminum conducts heat easily. If the process is done in a slow rate, there are higher risks that the material will suffer excessive burns that would affect the creative appearance of the product.
If you find yourself in need of aluminum welding service some day, be sure that the service provider you will ask knows how to do this process properly since this technique is a very sophisticated one. It takes a lot of mastery to be able to perform this well.
