Welders Home >> Aluminium Welding

Aluminium parts is replaced more and more parts today onwards.Why? Aluminium is smallweight, hard-wearing, and low-cost in comparison with other metals. The problem is, most renovate shops have been trained that it required costly machinery to weld aluminum properly.

Aluminum melts at 1218o. Unfortunately, it doesn't spin red like other metals before it reaches the point that it liquifies. If you've ever tried to weld aluminum you know that without an correct temperature guide, you may end up clean-up your aluminum off the floor. For this reason, Many shops in the past have recommended replacing aluminium parts rather than repairing them--which is not only costly but unnecessary. Fortunately, times have changed.

Our single line of aluminum welding alloys and fluxes work synergistically to act as an accurate temperature guide when welding aluminum. Aluminium welding products are sold with out the flux, we believe the use of flux to be better for several reasons.

Welding Of Aluminium

The aluminium welding has met with great difficulties by reason of the great talent of corrosion of the welding material. The moment it has been organized and cleansed, the aluminium is at once enclosed with aluminium oxide, which prevents the pieces fusing together. By using a flux, however, the corrosion skin is dissolved, and a dross is at the same time shaped which enables the metal to flood and make a perfect welding. The weld of aluminium remains unconcerned in solutions of general salt and soda, and is in each and every respect comparable with rolled aluminium. There are various systems for soldering aluminium welding , and for welding; for instance, those of M. D. Schocp and W. C. Heraeus.



The former is described as follows: -

The plentiful alloys of the aluminium-copper-tin or tin-bismuth-copper type, which have been used for soldering aluminium welding at somewhat low temperature, are all open to the same hostility, that the soldered joint little by little loses its cohesion, i.e., mechanical strength. This is due to the fact that aluminium welding , mainly in the presence of water, compares unfavourably with other metals on account of the "electrolytic local action," the aluminium becoming slowly decomposed.
