Surgical anvil arrangements

A surgical stapling anvil, comprising:

• an anvil body, comprising:
• a tissue-facing surface;
• a plurality of staple forming pockets defined in said tissue-facing surface;
• and
• a longitudinal slot, defining:
• a first portion comprising a first width, wherein said first portion is configured to receive a cutting edge of a firing member therethrough;
• and
• a second portion comprising a second width greater than said first width, wherein said second portion is configured to receive an anvil-camming portion of the firing member therethrough;
• and
• an anvil cap welded to said anvil body, wherein said anvil cap comprises:
• a welded segment;
• and
• a non-welded segment, wherein said non-welded segment comprises a non-welded width, and wherein said non-welded width is no greater than 105% of said second width.

A surgical stapling anvil, comprising:

• an anvil body, comprising:
• a tissue-facing surface;
• a plurality of staple forming pockets defined in said tissue-facing surface;
• and
• a longitudinal slot, defining:
• camming ledges, wherein a first width is defined between said camming ledges, and wherein a cutting edge of a firing member is configured to traverse between said camming ledges;
• and
• anvil slot walls, wherein a second width greater than said first width is defined between said anvil slot walls, and wherein an anvil-camming portion of the firing member is configured to traverse between said anvil slot walls;
• and
• an anvil cap welded to said anvil body, wherein said anvil cap comprises:
• a welded portion;
• and
• a non-welded portion, wherein said non-welded portion comprises a non-welded width, and wherein said non-welded width is less than or equal to about 105% of said second width.
