This relievesthe strain due to uneven contraction of the metal. , 1911. AMERICAN ENGINEER AND RAILROAD JOURNAL 205 On engine No. 5818 both side sheets were welded in. The Driving Boxes. length of one side seam being 102 in. piece of driving box was broken off and the space was filled up, as shown in the The following is an itemized cost of the above weld: Labor—18 hrs. at 50Hc per hr. ^.Material—380 ft. gas, carbide =... $ -$ After welding no roundhouse repairs are necessary, such ascaulking, replacing rivets, etc., and it is considered that thewelded joints soon pay for themselves in this way.
