SPECIAL COMMITTEE ON CONTINUOUS WELDED RAIL

Rolling-load tests were made of specimens of continuous welded rail in the 12-in stroke machine on four acetylene welds, 4 electric welds, and 4 thermit welds. All of the thermit welds failed in this test. One acetylene weld also failed just below 2 million cycles. Other rolling-load tests were made in a 33-in. stroke rolling machine primarily to test the welds in the rail bases. All the acetylene and electric welds ran to over 2 million cycles without failure. Two thermit welds developed failures in the rail heads. A few other observations on possible causes of weld failures are listed, including grinding burns electrode burns, and cases where the flame goes out in oxyacetylene welding. The fastenings subcommittee reports five methods used to anchor welded rail across open-deck steel viaducts or long deck steel spans.
