High carbon steel welding defect

WebThe cracks can be wide and open and possibly narrow. Solidification cracking occurs in compositions having a wide freezing temperature range. For steels, solidification cracks occur due to the presence of high carbon content and impurity elements like sulfur and phosphorus.During solidification, these elements segregate such that intergranular liquid … Web13 de abr. de 2003 · Short answer: repass the welds. If you rerun the weld it can drive out the pores and increase the weld penetration as well as improve the weld appearance. In EB welding it is called a cosmetic pass but it is a really useful means of cleaning up a weld. Topic Welding Industry / Technical Discussions / welding carburized, high carbon steel.
