Thank you both.
It should have been obvious to me but as elsewhere they are talking about quantity of filler metal etc. was put off course.

I agree with MoiraB's suggestion. A smeary "l'arc" could very well be recognised as "Tare".

Could this possibly be a scanning error for soudage à l'arc? Having googled soudage à Tare + welding, many of the documents (even a European patent) didn't actually contain your term but did have soudage à l'arc (?) Plenty of ghits for the phrase "soudage à l'arc des nickels et alliages de nickel" - in fact there's a Belgian standard (NBN EN ISO 15614-1) called Descriptif et qualification d'un mode opératoire de soudage pour les matériaux métalliques - Epreuve de qualification d'un mode opératoire de soudage - Partie 1: **Soudage à l'arc et aux gaz des aciers et soudage à l'arc des nickels et alliages de nickel** (ISO 15614-1:2004). I rest my case...
