摘要：
The invention relates to a braze-welding or arc-welding method using a TIG torch equipped with a non-consumable electrode (1) and a consumable filler wire (2) of a given diameter, wherein the transfer of metal to the welded joint occurs in successive droplets of molten metal deposited at a frequency of between 20 Hz and 90 Hz, and the size of said drops is between 1, 2, and 4 times the diameter of the consumable wire.
