Hi, Please find below. First you find how many minutes has the welding taken, multiply this by the flow rate (in litres per minute) then divide by 1000 to give you the amount of gas used in cubic metres For example a pipe butt takes you 15mins to weld and you use a flow rate of 6 ltr per min and you have 20 butts to weld. 15X6X20 = 1800 litres of gas used. This equates to 1.8 cubic metres of gas. You can also calculate how many butts you should get per cylinder 15X6 = 90 litres or 0.09 cubic metres of gas per butt Argon cylinder contains 12.10 cubic metres so 12.1 divided by 0.09 = 134.4 butts per cylinder of argon With regard purging, just do the same. Length of purge time X flow rate divided by 1000 Thanks & Regards, (Karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.
