TIG, MIG and MAG welding

How it works

In TIG welding the arc burns between a non-consumable electrode and the workpiece, and the welder adds filler separately. That gives a lot of control and a calm bead. In MIG and MAG the filler wire is the electrode itself, which is faster and therefore better suited to longer welds.

Where it fits

Manual welding is the route for one-offs, repairs, awkwardly reachable joints, and products that still need judgement while they are being welded.

What we are qualified for

The welder qualifications were taken at Lastechniek Oost and cover material group 1.1 and 1.2 (steel) and material group 8 (stainless steel). For each group they cover a TIG fillet weld from 1.4 to 3 mm plate thickness, welded in a single layer, and a V-butt weld in pipe from Ø 25 mm with a wall thickness of 3 to 10 mm.

Besides steel and stainless steel, we also weld aluminium. Work outside the ranges above is not ruled out; it simply falls outside what these qualifications cover. Put your assembly to us with the enquiry.

Frequently asked questions

What is the difference between TIG and MIG/MAG welding?

In TIG welding the arc burns between a non-consumable electrode and the workpiece, and the welder adds the filler separately; that gives a lot of control and a calm seam. In MIG and MAG the filler wire itself is the electrode. That is faster and therefore better suited to longer seams.

Which materials are your welders qualified for?

The welder qualifications were obtained at Lastechniek Oost for material groups 1.1 and 1.2 (steel) and material group 8 (stainless steel). Per group they cover a TIG fillet weld on 1.4 to 3 mm sheet and a V-groove weld in pipe from Ø 25 mm with a wall thickness of 3 to 10 mm.

Does Baas Metaal also weld aluminium?

Yes, besides steel and stainless steel we also weld aluminium. Work outside the ranges of the welder qualifications is not ruled out, but it falls outside what they cover. Please include your construction in the enquiry, so it can be assessed per part.
