WELDING OF STAINLESS STEELS
The thin but dense chromium oxide film which forms on the surface of a stainless steel provides corrosion resistance and prevents further oxidation.
There are five types of stainless steels depending on the other alloying additions present, and they range from fully austenitic to fully ferritic.
TYPES OF STAINLESS STEELS
The primary alloying additions are chromium and nickel. Ferritic stainless steels are non-hardenable Fe-Cr alloys. Types 405, 409, 430, 422 and 446 are representative of this group.
Types 403, 410, 416 and 420 are representative of this group.
They are identified as the 600-series of stainless steels (e.g., 630, 631, 660).
WELDABILITY OF STAINLESS STEELS
For any of these processes, joint surfaces and any filler metal must be clean.
The low thermal and electrical conductivity of austenitic stainless steel is generally helpful in welding.
Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher.
Alloying elements which appear in stainless steels are classed as ferrite promoters and austenite promoters.
The cebora pocket turbo 130 was one of the most popular machines in the uk. It was used for DIY welding and automotive industry and many are still in use today. The cebora Autostar 160 and Autostar 180 were the other two most popular machine for automotive and sheet metal workers. Welding equipment and cutting services have manufactured replacement parts for the Cebora Pocket Turbo 130 machines such as mig welding torches.
We have manufactured New Mig Torches for the Autostar 160 and the Autostar 180 machines. The autostar 160 and 180 modified torches use the MB15 consumables. Also the shroud is push on 53mm long 12mm long bore and the tips are 6mm thread, 25mm long. The pocket turbo 130 alternative torch uses MB14 consumables. However the shroud is screw on 38mm long 8mm bore and the tips are 5mm thread, 18mm long.
The gas nozzles, liners, contact tips, mig torch necks, carry handles, main contactors, fans, printed circuit board repair service, wire reel holders, rectifiers banks, the turbo 130 printed circuit board, clapper arm assembly and drive motor / gearbox are all no longer available.
