Abstract
A confined space welding apparatus which is to interiorly weld a tube to a structure such as a wall of an enlarged chamber. The position of the weld bead is initially determined through a set gage. This set gage is then employed to accurately position the welding electrode within the welding apparatus. The welding apparatus is includes collapsible handles to facilitate insertion of the welding apparatus within the enlarged chamber. The collapsible handles are then moved to their extended operable position and then the welding apparatus is securely clamped within a conduit positioning the welding electrode at the area to be welded.
Claims21
A welding apparatus for producing a weld on a workpiece, said welding apparatus comprising:
- a main housing having a longitudinal center axis, said main housing being tubular having an elongagted opening;
- a shaft mounted within said elongated opening, said shaft being longitudinally movable along said longitudinal center axis and rotatable about said longitudinal center axis, a welding electrode connected to one end of said shaft, said welding electrode being spaced from said main housing, said welding electrode being rotated by rotation of said shaft;
- securing means for longitudinally fixing said shaft relative to said main housing at a particular established position, said securing means being releasable permitting longitudinal movement of said shaft relative to said main housing;
- and
- handle means mounted upon said main housing, said handle means being movable between an operable position and a collapsed position, whereby said handle means is to be located in said collapsed position and said welding apparatus then moved through a confining opening into an enlarged internal chamber to be then utilized to weld with said handle means being moved to said operable position.
