ABSTRACT:
A method and apparatus for feeding coolant to the interior of a connecting pin during build-up welding of a track link assembly, for protecting the peripheral seal members of the connecting pin from the welding heat, comprising a coolant charging and discharging adapter having a forcibly butting conical shaped end to be placed in contact with an opening in the lateral end face of the connecting pin and an elongate pipe for feeding a coolant through said adapter into said connecting pin interior. The coolant is removed continuously or intermittently during welding through an annular passageway formed in the adapter concentrically about the pipe, or through a passageway similarly formed by an insertion portion carried by said adapter. The adapter is supported by a suitable support member, being aided by a compression spring disposed therebetween, and connected to a retractable mounting plate urged by fluid pressure operated cylinder and piston means for maintaining the adapter forcibly butted against the end face of the connecting pin.
