What a Programmed Weld Path Means for Repeated Parts
The cobot follows the same route from the first part to the last. What changes between parts is not the path, it is how well each part is held and prepared.
A weld path is a route the torch takes. Programming it once and running it two hundred times is what the Vectis cell does, and the interesting part is everything the path depends on.
What the machine does
A UR10e collaborative arm carries the torch along the programmed path. The cell lays a single continuous weld up to 9 ft 6 in (2.89 m), and covers 15 ft 8 in (4.77 m) of weldable travel without the material being moved. Beyond that the part is repositioned and the weld continues.
MIG runs on carbon steel, stainless steel and nickel, with 18 gauge as the minimum material thickness. Multi pass programming is typically used on welds larger than 3/8 in (9.5 mm), laying a heavier weld in layers rather than forcing it in one pass.
What makes the path repeat
The path is fixed. The variable is the position of the part. That is the fixture's job: hold each piece so the joint sits where the program expects it. Simple fixtures are made for repeat parts and quoted with the work, because a fixture only earns its place when the part repeats.
The second variable is the part itself. A blank cut from the stored program, a bend formed to the same backgauge values and a joint prepared the same way arrive at the cell consistent. A part assembled by hand with a gap that varies piece to piece will show it in the weld, no matter how good the path is.
What the cell is not being asked to do
It is not a claim of distortion control, stress relief or a welding procedure for a customer design. It welds a joint that is reachable and held, in a sequence that is decided at review. Where a job has odd single parts, tight access or out of position joints, it goes to a hand welder, and the choice between them is made on the work rather than on preference.
The preparation checklist
- Material and thickness, since 18 gauge is the floor for the cell.
- Joint type and where the weld runs, including which side is visible.
- Whether the joint repeats on every piece in the run.
- The overall size, against the 9 ft 6 in continuous weld and 15 ft 8 in travel figures.
- Whether a fixture is acceptable as part of the order.
Where this connects
Ordering parts or a completed welded assembly is the scope question that comes first. The equipment behind it, including the arm and the weld envelope, is on the cobot machine page.
