           Prevention or minimization of distortion
           Several ways can be used to minimize distortion caused by shrinkage:
           1  Do not over weld
           2  Control fitup.

           3  Use intermittent Welding
           4  Use as few weld passes as possible
           5  Place welds near the neutral axis
           6  Balance welds around the neutral axis
           7  Use back step welding

           8  Anticipate the shrinkage forces
           9  Plan the welding sequence
           10 Remove shrinkage forces after welding
           11 Minimize welding time

           12 Use the smallest leg size permissible when fillet welding.
