The weldability of TCS corrosion resistant stainless steel for railway wagon was investigated by cold cracking sensitivity test, HAZ maximum hardness test and varestraint test.

50 mm WNQ570 steel,a new type of steel for railway bridge,has been carrying on the experiments of cold crack sensitivity through CJ607Q welding rod and submerged WS03 arc welding wire and SJ101Q welding flux.
