To Delete Welding Materials
When you delete a welding material that is assigned to a weld, you must also delete the weld that uses that material. To avoid having to delete the weld, first unassign and then delete the material.
Use one of the following procedures to delete a welding material:
• In the Weld and Joint Tree, right-click a welding material and choose 
Delete from the shortcut menu.
Delete from the shortcut menu.• Click > 
Welding, and on the Welding tab, click 
Weld Material. The Weld Materials dialog box opens. Right-click a material in the list, and choose Delete from the shortcut menu.
