文章摘要： The present paper describes cracking behavior during the submerged arc welding of medium carbon steel plates (0.45% C). It discusses the results of tests made to examine the effect of welding variables (current, welding speed and wire feed rate), plate fabrication conditions (rolling reduction ratio) and plate thickness on cracking susceptibility using trans-varestraint tests. It is found that the cracking susceptibility increases with an increase in the welding current, and decreases with an increase in the welding speed or the electrode wire feed rate. It also increases with increases in the plate rolling reduction ratio and with decreases in the plate thickness. These results have a practical significance for industrial fields, especially where welded machine spare parts are concerned.
