Actualy I need the Standard Operation Procedure (SOP) to be established in my co.'s shop floor and then conduct the "Work Measruement" to obtain the STD Time. Since the Arc, TIG, MIG, and Spot welding are widely used, could anyone recommend some useful website or advice...How could I get the STD time for these welding works without conducting the "wrok Measurement". This could be the "Synthetic Time"...please advise...Thanks
