Laser Welding
Every vendor selling handheld laser welders in Canada gets asked the same question, and almost none of them answer it in writing: we are a CWB-certified shop; what happens to our certification if we bring in a laser welder? Here is the honest version, framed the only defensible way: as your obligations, not as anyone's promises.
CWB certification under W47.1 attaches to the company. It covers your shop, your welding supervisors, and the welding procedures your shop has qualified and registered under CWB's published framework. It is not a property of any machine on your floor, from any manufacturer, at any price. A welding power source has never carried your certification for you, and a laser welder does not either.
That cuts both ways, and both directions matter to a buyer:
Under CWB's framework, a certified shop that adds a welding process it has not used before takes on a procedure-qualification obligation: the shop must qualify its procedures for that process with CWB before relying on it for work that has to comply. This is exactly the same obligation your shop already understands from the arc processes. The process changes; the logic of certification does not.
What nobody should tell you, including us: what CWB will accept, how long qualification takes for a laser process, or what it costs. Those answers belong to CWB, they are specific to your shop and your work, and any vendor who promises an outcome is selling past the close.
The arc processes have decades of precedent inside Canadian certification. Laser beam welding has far less. For a certified shop this means two practical things. First, expect the conversation with CWB to be more bespoke than it would be for another MIG machine. Second, do not treat the thinner precedent as a prohibition; treat it as a reason to start the CWB conversation before the purchase order, not after the crate arrives.
Take this list into your call with CWB and your engineering support:
One honest hour with CWB before purchase is worth more than any assurance an equipment vendor can put in a brochure.
A certified shop rarely runs 100% code-governed work. Handheld laser welders typically enter Canadian shops on the work that is not: fixtures, shop furniture, repairs, non-structural fabrication, and jobs where the governing spec leaves the process to the fabricator. Whether any given job is code-governed is a question for the code covering that job and for your engineer of record, and it is your call to make, not ours.
There is also a category most shops overlook: two of the head's four modes are not welding at all. The Vantix platform is a 4-in-1: weld, clean, light cut and seam-clean on one gun. Pre-weld surface cleaning and post-weld seam cleaning are surface processes, and shops put those modes to work from day one regardless of where the welding-procedure conversation stands.
The economics of that day-one work are covered in the welder shortage math, and the ramp itself in how long it takes to train a laser welding operator: 4× faster than MIG/TIG, with operators trained in days, on machines from $32,000 CAD with a 2-year warranty.
We will tell you exactly what the machine does, because it is published: air-cooled 1.5, 2 and 3 kW and water-cooled 2 and 3 kW; maximum weld thickness of 6 mm at 1.5 kW, 8 mm at 2 kW and 10 mm at 3 kW; stainless, carbon steel and galvanized, plus aluminum and copper/brass at 3 kW; single-wire feed standard with dual-wire optional. Every system carries a 2-year warranty, 5-day on-site training, spares stocked in BC, a 24/7 Canadian hotline and 48-hour on-site service in Western Canada.
We will not tell you that any of that substitutes for your shop's own certification obligations, because it does not. Vantix claims no CWB credential for this equipment, and no equipment vendor's paperwork stands in for the qualification work your shop does with CWB. If you want the comparison against the process you would be displacing, read laser welding vs TIG. If you want to talk through where a laser welder fits your mix of code and non-code work, book a demo at the Lumby, BC showroom.
No purchase does, in either direction. Certification attaches to your shop, supervisors and qualified procedures, not to equipment. Adding a new process creates an obligation to qualify procedures for it with CWB before using it on work that must comply. Talk to CWB before you issue the PO.
Approval is not a property of a process in the abstract; shops qualify specific procedures. Laser welding has less precedent in the framework than the arc processes, so the only authoritative answer on what qualification involves for your shop comes from CWB directly. Be suspicious of any vendor who answers this question with a yes.
That is how these machines typically enter certified shops: on repairs, fixtures and non-structural fabrication, plus the head's cleaning and seam-cleaning modes, which are not fusion welding at all. Whether a given job is code-governed is determined by the code covering it and your engineer of record.
Handheld laser welding runs about 4 times faster than MIG or TIG on comparable joints.
The speed comes from a concentrated energy source and much lower heat input. The lower heat input is arguably the bigger effect: less distortion on thin sheet means less post-weld straightening, and cleaner welds mean less grinding and polishing.
On thin stainless the finishing time saved is often larger than the welding time saved, which is why a straight arc-time comparison usually understates the difference.
Stainless steel, carbon steel and galvanized steel, plus aluminum. Copper and brass are supported at 3 kW.
The low heat input also makes the process practical in places conventional welding struggles: near heat-sensitive components, on thin-to-thick joints, and on finished or coated assemblies where distortion would be visible.
Single-pass capability is up to 0.24 in (6 mm) at 1.5 kW, up to 0.31 in (8 mm) at 2 kW, and up to 0.39 in (10 mm) at 3 kW.
Most shops buy on the joints they run every day rather than the thickest joint they can imagine. Laser welding's advantage is largest on thinner material, where conventional heat input causes the distortion that forces straightening and rework, so sizing up for an occasional heavy joint often buys capability in the wrong place.
