A portable machine for electric arc welding and air carbon arc gouging on vertical wall surfaces is disclosed. A table-mounted carriage arm carrying a vertical positioning assembly for welding nozzles or a gouging torch is driven horizontally around a vertical axis of rotation while guide wheels on the carriage arm traverse the wall surface or traverse a flexible guide secured to the machine table through a system of support arms when a rough wall surface is involved. The carriage arm is biased yieldingly toward the wall surface during its horizontal traverse and the vertical positioning assembly adjusts itself automatically on its vertical axis to maintain proper welding nozzle and gouging torch alignment with the wall surface undergoing repair. A constant speed of movement of welding nozzles or a gouging torch across the wall surface is maintained. The welding nozzles or gouging torch are motor-driven vertically on the positioning assembly.
A machine for reconditioning substantially vertical walls by gouging and/or welding operations comprising a table assembly adapted to be positioned and releasably locked in a use position relative to a substantially vertical wall, a substantially horizontal carriage arm assembly secured to the table assembly and being rotatable relative to the table assembly on a substantially vertical axis of rotation, rotational power means connected between the table assembly and carriage arm assembly, an upright weld metal depositing and/or gouging assembly mounted on and being bodily carried by the carriage arm assembly, means forming a vertical axis rotational connection between the carriage arm assembly and said upright weld metal depositing and/or gouging assembly, substantially horizontally projecting guide means on said last-named means and adapted to follow the horizontal profile of a substantially vertical wall undergoing reconditioning by the machine and to impart vertical axis rotation to said upright weld metal depositing and/or gouging assembly to maintain the latter in correct alignment with said wall, and yielding power means connected with the carriage arm assembly and biasing it in a linear horizontal direction to maintain said guide means in engagement with a surface to be followed by the guide means during operation of the machine.
A machine for selectively depositing weld metal on the vertical side wall of a paper pulp mill digester or for carbon arc gouging a surface of said side wall in preparation for welding, said machine comprising a table assembly adapted to be supported at a required elevation adjacent to said vertical side wall and adapted to be releasably locked in a use position relative to the side wall, an adjustable contour substantially horizontal elongated guide device adjustably connected with and supported by the table assembly and spaced substantially horizontally outwardly therefrom and being adapted to engage said side wall and conform substantially to the horizontal profile thereof, a substantially horizontal rotatable carriage arm assembly on the table assembly including forward end guide means engaging and following said guide device during rotation of the carriage arm assembly, means yieldingly biasing said forward end guide means into engagement with said guide device, and an upright weld metal depositing and/or gouging assembly on the carriage arm assembly.
A machine for reconditioning a substantially vertical metal wall of a paper pulp mill digester or the like comprising a supporting base, an adjustable contour substantially horizontal guide device, adjustable means interconnecting said guide device and supporting base and supporting the guide device on said base and being operable to adjust the profile of the guide device, a substantially horizontal rotatable and longitudinally extensible and retractable carriage arm on the supporting base and having a forward end guide means engaging and following said guide device during rotation of the carriage arm around a substantially vertical axis of rotation, yielding means connected with and biasing the carriage arm and forward end guide means toward said guide device, and metal gouging and metal welding means mounted on the carriage arm and moving therewith relative to the vertical metal wall being reconditioned by the machine.
