FIELD: process engineering.
SUBSTANCE: invention relates to device and method of measuring protective gas 8 in arc welding by analysing it after escape from gas nozzle 27 of torch 10. To analyse protective gas, external instrument incorporates, at least, one pickup 31. Said pickup 31 is arranged at distance 38 from torch 10 equal, in fact, to distance 38 between torch 10 and part 16 in welding to allow simulation of protective gas escape and effects like in actual welding conditions. Pickup 31 is connected with processing unit 32 and, via said unit, with welding apparatus.
EFFECT: fast, accurate and efficient estimation of protective gas effects.
