Spout Welding
Machine (Laser)

Leaks are the thing that matters most in spout welding, and it's where we are least willing to be vague. A leak usually comes from two places: the fit-up gap between spout and body, or the weld path not matching. Laser welding is very sensitive to gap — too wide and it won't penetrate, too tight and it burns through. We clamp the spout into position with a locating fixture first, then weld with parameters calibrated to that part, not to a welder's feel.

A laser seam is narrow with no raised bead, so normally it needs no grinding. If the seam lands on a visible face and the part must be mirror or brushed finish, it still gets one polishing pass. That's still less work than TIG — the bead you get at a kettle rim with TIG almost always has to be ground off, and that's one more process and one more person.

Yes, but the tooling is completely different. A single-wall kettle is thin (0.4–0.6 mm), so power comes down and speed goes up. A double-wall pot welds the joint between inner and outer shells, and the vacuum layer must not be breached. One fixture cannot do both. Send the shapes and wall thicknesses and I'll tell you whether it should be two machines.

Yes, provided cycle time and load/unload method agree. Either a standalone station with manual loading, or inline in your conveyor so parts flow automatically. Inline needs communication and cycle synchronisation (stop when upstream is empty or downstream is full), which is line integration work and gets laid out on the drawing.

Driven by spout type, whether you need automatic loading, and whether it goes inline. A single station with manual loading and an inline unit are two different budgets. Send spout type, wall thickness and required cycle time, and I'll quote a range against a proposal.

The laser source itself is maintenance-free, but protective lenses are inspected and replaced on a schedule — spatter contaminates them and a dirty lens costs you power. It's a normal consumable, not expensive, but it has to be changed on time rather than after you notice the weld doesn't penetrate.

Sampling is the right starting point. Send spouts and bodies, a dozen sets each. We weld them and show you the seam appearance plus a pressure or leak test, so you can judge whether the seam is acceptable.

If spout position or angle changes, you change the tooling and re-teach the path. Different batches of the same spout only need parameter tweaks. How many spout types you run and how often you switch is what decides whether we build quick-change tooling.
