Abstract
A method of securing a sealing washer to one surface of a metal sheet while welding a head of a fastener to a second surface of a metal sheet, the method comprising: compressing the head onto the second surface of the sheet between a first electrode engaging the head and a second electrode engaging the first surface of the sheet, welding the head to the second surface of the sheet by electrical resistance welding to heat the first surface of the sheet proximate to the first electrode, urging a sealing washer into the heated first surface with the second electrode to heat the sealing washer and thereby bond the sealing washer to the first surface.
Claims22
A method of securing a sealing washer to one surface of a metal sheet while welding a fastener to a second surface of a metal sheet;
- the method comprising:
- bonding the fastener to the first surface of the sheet by a process which to achieve such bonding heats the second surface of the sheet proximate to the fastener,
- urging a sealing washer into the second surface while so heated to heat the sealing washer and thereby bond the sealing washer to the second surface.
A connecting plate comprising
- a metal sheet having a first surface and a second surface with an opening therethrough,
- a metal nut having an aperture therethrough,
- the nut welded to the first surface with the aperture of the nut in alignment with the opening,
- a sealing washer with a hole therethrough,
- the sealing washer secured to the second surface with the hole of the washer in alignment with the opening,
- the washer secured to the second surface by a process including urging the washer into the second surface while heating the washer with heat generated by welding of the nut to the metal sheet.
A connecting plate comprising
- a metal sheet having a first surface and a second surface with an opening therethrough,
- a stud having a head and a shank extending therefrom,
- the head of the stud welded to the first surface with the shank extending through the opening,
- a sealing washer with a hole therethrough,
- the sealing washer secured to the second surface with the hole of the washer in alignment with the opening,
- the washer sealed to the second surface by a process including urging the washer onto the second surface while heating the washer with heat generated by welding of the head of the stud to the metal sheet.
An electric resistance welding electrode having an electrode face to engage a surface of a metal element,
- a socket extending into the electrode from the face to a socket end,
- the socket adapted to receive a seal member therein and for urging the seal member into the surface of the metal element while the electrode face engages the surface.
