Preparation of solder joint
Soldering aluminum with fusible solders on the basis of catch is mainly used in the home, and for connections that are not subjected to significant operating loads in operation. The following is done in sequence:
- The aluminum is carefully cleaned of the thin but very strong oxide film of Al2 O3 dioxide. This can be accomplished by mechanical oil cleaning or by cleaning with chemical solvents. In the first case, any mineral oil that has no water in its composition is used; emulsions are not suitable. The second method consists of cleaning with fluxes containing refractory fluorides or chlorides of alkali metals;
- The cleaned surface is immediately treated with iron trichloride, which is mixed with tin solder. This composition produces a final abrasive cleaning of the surface to be soldered;
Copper
A thin layer of copper is applied to the surface. This can be obtained either by electrolysis or by coating the surface with a layer of flux containing copper. The supplier Evek GmbH offers a wide range of solder tin at an affordable price. We provide delivery of products anywhere in the continent. The price is optimal.
Soldering technology
Tin solders in the technology of joining aluminum products from alloys such as AMz and the like are used in the following way:
- The parts to be joined are heated to temperatures of 160...380 ° C;
- On the surface of the future soldering flux is applied;
- By short movement of soldering iron the flux and solder are melted and the whole joint is covered with it. Prolonged exposure to high temperatures leads to spontaneous annealing of aluminum, as a result of which its strength is markedly reduced.
Soldering large aluminum billets with tin is not recommended because of the risk of warping the joint.
