New method for determining cooling time and preheating temperature in arc welding

Study and research on arc welding have provided identification of errors in formulas for calculating the cooling time t8/5 and other dependent parameters. It is concluded that large errors are present in certain intervals which had caused fail?ures in welding technologies. Incorrect approximation of...

description Study and research on arc welding have provided identification of errors in formulas for calculating the cooling time t8/5 and other dependent parameters. It is concluded that large errors are present in certain intervals which had caused fail?ures in welding technologies. Incorrect approximation of cooling temperature is replaced by a more accurate approximation used for defining of the new precise algorithm for determining relevant welding parameters. nema
