Abstract
Contact beads of noble metal are welded to a substrate of less corrosion-resistant metal in an apparatus in which one electrode formed with a receptacle is moved cyclically between a welding position adjacent another, stationary electrode and a remote feeding position. A gap between the electrodes receives the substrate, and blanks of contact bead material are fed into the laterally open receptacle through a stationary guide aligned with the receptacle in the feeding position of the movable electrode in a direction transverse to the direction of electrode movement.

Apparatus for welding a contact bead to a face of an electrically conductive substrate comprising:
- a. a base;
- b. a first electrode fixedly mounted on said base;
- c. a second electrode movably mounted on said base;
- d. actuating means for moving said second electrode between a welding position adjacent said first electrode and a feeding position remote from said first electrode, ,p2 1. said electrodes in said positions defining therebetween a gap adapted to receive said substrate,
- 2. said second electrode being formed with a receptacle open toward said first electrode in the direction of movement of said second electrode and open in a direction transverse to said direction of movement;
- and
- e. feeding means for sequentially feeding blanks of contact bead material to said receptacle, said feeding means including a guide member fixedly mounted in said base and defining a path of movement for said contact bead material aligned with said receptacle in said feeding position and said second electrode, said path extending in said transverse direction.
A method of welding a contact bead to a face of an electrically conductive substrate which comprises:
- a. inserting a blank of contact bead material into a receptacle of one welding electrode in a predetermined direction;
- b. moving said one electrode transversely of said predetermined direction toward another welding electrode and toward said face while said substrate is interposed between said electrodes until said blank engages said substrate and holds the engaged substrate in contact with said other electrode;
- and
- c. passing welding current between said electrodes through said blank and said substrate.
