A paint booth arrangement maximizes floor space and efficiency of a painting operation. The arrangement comprises an equipment enclosing structure and certain air handling equipment specifically configured within the structure. The structure comprises forward and rearward sections, opposed wall sections, a centralized roof section, and opposed wall-to-roof sections, which sections define open space having varied elevation for receiving paintable equipment. The air handling equipment comprises an air intake and exhaust assemblies and an air replacement system. The air intake and exhaust assemblies extend coextensively intermediate the wall sections at the rearward section and function to support portions of the air replacement system. The air replacement system comprises conduit extending intermediate the forward and rearward sections as defined by the wall-to-roof sections. The air intake assembly communicates with the conduit for directing inlet airflow to the open space, and the air exhaust assembly comprises exhausts airflow from the open space.

A gap welding process () for manipulating a movable robotic welder () for making a weld between two or more substantially immovable work pieces () using a higher level programming language (). The gap welding process () performs a data transfer routine which takes spreadsheet data () representing expected variables, runs a data conversion program () that creates weld program data including point position, user frames (and), weld schedule, seam tracking schedule, weave schedule, azimuth orientation, travel speed, wait time, weave type and number of digital output control data. The gap welding process () also performs a gap-sensing routine () for actual weld gap measuring by using the robotic welder () to touch specific locations on pieces forming the gap or fixturing to produce weld variance data. The gap welding process () then uses a weld control program in conjunction with the weld program data (), weld variance data (26), and feedback data () that is gathered during the welding process to determine and perform the correct manipulation required to produce torch movements to accurately weld the gap ().

Gap welding process

A rail restraining, robotic welding and weld delivery device uses a frame for supporting a welding head with a clamp for restraining a first rail end and a second rail end and a base twist assembly for aligning said first end and second end. An interconnected weld containment apparatus pivotally connects to the clamp by use of a cam actuated linear pin. This arrangement is operable in an environment in clearance between rails and sufficiently compact that it may be operated from and carried in a truck based on a standard over the road truck or from a container.

A rail restraining ( ) and weld delivery device ( ) uses a frame for supporting a welding head with a clamp ( ) for restraining a first rail end and a second rail end and a base twist assembly ( ) for aligning said first end and second end. An interconnected weld containment apparatus ( ) pivotally connects to the clamp by use of a cam actuated linear pin ( ). This arrangement is operable in an environment in which clearance between rails is about 7 to 11 inches and sufficiently compact that it may be operated from and carried in a truck based on a standard over the road truck.
