Method of assembling a first thin copper part and a second thin aluminum part, each to be welded using heterogeneous welding, includes placing the ends of the parts so that they face one another and pressing the ends against one another so as to constitute a welding zone extending therebetween; and applying an aluminum alloy by way of filler metal to the welding zone using a low energy welding method in which the electric arc and the meltable filler wire are wider than the combined thickness of the parts, the parts being held so as to maintain the welding zone at the top using a fixing element including at least two rigid blocks of a conductive material whose thickness is between 1 and 2 mm, whose length is greater than that of the parts and whose width is sufficient to hold the parts, and a pressure fixing system.
