Welding technology

Axxair facing tools AS a global player in the tube processing world, Axxair has enlarged its offering of innovative facing tools for thin wall tubes. This new DC range is complementary to the orbital cutting and welding machines.

The 2" head offers two additional new features: endless cutting tool adjustment from outside that offers optimal use of all the edge of the tool bits to get better productivity and a planetary reduction integrated in the head itself for maximising torque from the battery drill and therefore always allowing correct speed adjustments. Last but not least, Axxair has launched a DC 221, allowing facing up to 8" tubes with concentric clamping coming from its cutting range. The main advantage is to avoid the use of clamping collets for each diameter that needs to be faced. The concentric clamping system through six clamping jaws offers a unique wide range from 2" to 8". The 2" and 8" machines can also use an angle tool holder for making small bevelling when requested for welding. Wherever and whenever you have to work on thin wall tubing, Axxair can give an optimised response through orbital cutting, facing and welding machines. Those machines are shown on the website www.axxair.com through online videos to give you an exact idea of their advantages.

screwing and can be plugged ontoAxxair heads for facing tubes that usually need to be squared before automatic welding. Squaring a tube is requested to avoid chips to scratch electro polished tubes mainly in semiconductor and pharmaceutical industries to get the end of the tube perpendicular when it has been cut with a band, for example. Orbital welding machines need precise preps in order to ensure the welds are sealed correctly: the orbital cutting machines and/or the facing tools are the best response.

They are innovative as they offer a unique quick fit system allowing the customer to easily change from one head to another in order to cover a wider range of tubes with same power tools. The very powerful battery drill can therefore be used as a normal drill with a chuck for drilling holes or just for

programs that interface the saddle and elbow cutter to your PC. Rotation speeds range from 0.3rpm to 3.7rpm. This machine can be set up for oxy- fuel or the plasma process. Although this machine is designed to perform a great deal of work, it is an extremely economical choice and portable enough to sit on a worktable. Bug-O Systems was originally developed to fabricate the landing craft used on D-Day during World War II. Since that time, the company has been continually developing new products to give customers an excellent return on their investment. From the St Louis Arch to the Disney Cruise ships, and now pipelines all around the world, Bug- O’s full line of products and components can be designed to fit virtually any application.

BUG-O Systems is an expert in motion control and automating cutting and welding. It offers a large product range including an entire line of circle burner and circle welders and pipe cutting and profiling machines. The SE2-PTD is a programmable saddle and elbow cutter by way of its pendant, capable of passing 2" to 4¾" (50mm to 120mm) through the centre of the machine. The machine can also cut pipe larger than 4¾" by chucking on the face of the unit; maximum capacity is 16". When the machine is in pipe mode the operator has the ability to make the following preprogrammed cuts buy entering only the pipe size data required. The cuts are saddles, offset saddle, laterals, mitres and holes. A second mode can be selected to cut customised shapes in pipe. Also available are two
