Located in Napier, Profile Boats have a long history of working with Weldwell to increase productivity and create premium quality welds for their aluminium pontoon boats with Miller welders.

Designed initially as a safer beach launching vessel, the Profile Boats range has been developed to provide crafts from family recreation, to seriously good dive and fishing boats, as well as commercial charter vessels. The inherent safety of the unique aluminium pontoon design offers superior stability and makes all Profile Boats virtually unsinkable.

Ranging in size from 4.5m – 9.8m, the boats crafted in their Napier workshop need to be strong and safe, the welds that hold the boats together are exposed, so they require good quality, aesthetically pleasing welds.

Profile boats use Miller welders throughout their factory, using them for their reliability, leading to increased productivity and cleaner welds.

Using Miller’s Aluma MIG aluminium welding system, a dedicated aluminium system for advanced MIG and synergic pulsed MIG performance, Profile Boats can create MIG welds that provide a TIG appearance with the simplicity and productivity of MIG welding.

Profile Boats weld a lot of long MIG welds, the Aluma makes this easier with longer leads and syncronised, true push-pull wire feed system, offering precise wire feeding and arc performance.

In addition, the remote adjustment means they can adjust the wire speed while welding from inside the boat.

Welding with Miller & The Need For Speed

Motorsport vehicles typically require hundreds of parts which in turn need hundreds of welds. Most welds join intersecting tubes that make up the frames and roll cages in racing cars. Depending on which motorsport you’re looking at, vehicle requirements differ. For instance, NASCAR cars have a minimum weight of on average slightly above 1500 kg.

Due to the amount of precision involved during the manufacturing process for the different parts of the vehicles in motorsport, it is imperative that welders know their material and ensure that they have not just the right equipment to work on, but also the best, if possible. The chassis, spoilers, seat brackets, and the rear end housings connected to the upper and lower control arms, including intercoolers and radiators are amongst the many welded race car parts. With the intensity and risks involved on the track, the strongest components and best fabrication are required – right from the frame, roll cage to even the cooling units which needs consistent structural integrity to provide the unique combination of safety and performance.

A critical part of a race vehicle is the intercooler unit which allows the intake air charge to be cooled before it flows into the engine thus adding to the horsepower. Generally, for most cars, the intercoolers sit in front of the radiator which in turn offers superior air cooling over intercoolers mounted over the top. There are a couple of factors which decide the quality of the intercoolers: 1) the internal flow characteristics and 2) the cooling fins. In an ideal situation, the fins should have as large a surface area as possible together with the internal core benefitting from a low number of tapered bends and there should be no internal welds that might result in turbulence.
