| Abstract: | The typical half theoretical formula of wire melting rate and measuredrelevant constants are used for calculating stable extension of wire and it' s reco vervtime constant in GMA welding. Then the calculated results are examined by using arcphotography arc high speed cine camera and high speed event analyser. The effects ofresistance heat of wire extension on stability of arc length are discussed. |
