As an alternative to the functional tolerances in Annex B,BS EN 1090-2 does allow the use of BS EN ISO 13920; this is more likely to be used in cases of heavily welded structures where distortion from welding is the dominant factor in determining the dimensions and shape.That standard specifies general tolerances for linear and angular Bridge Standards and Procedures Manual - Volume 1Low Volume Road (LVR) Structure means a bridge or structure,as designated by the Ministry,on a side road with an average daily traffic ADT (for a period of high use) total in both directions,not exceeding 400 vehicles per day.Numbered Routes are not considered asCOMMONWEALTH OF PENNSYLVANIA DEPARTMENTpart 4,structures.specifications and as supplemented by the design manual,2.design specifications aashto lrfd bridge design bending or welding of reinforcement bars is indicated.reinforcement steel.do not use rail steel (a 996) where requirements of astm a 615,a 996 or a 706.do not weld 1.provide grade 60 deformed reinforcing bars

The simple laser weld,in conjunction with high speeds,results in welds with little or no tolerance for fit-up gaps,making this type of weld inadequate in certain situations.In autogeneous laser welding,the gap between parts is limited to small tolerances,otherwise burn through will occur ( Ono et al.,2002a ).
