WELDING OF STAINLESS STEELS

INTRODUCTION

Defined as iron base alloys, the stainless steels contain at least 10.5% chromium. These contain at least 10.5% chromium.
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
Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common.
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.
Martensitic stainless steels are similar in composition to the ferritic group but contain higher carbon and lower chromium to permit hardening by heat treatment.
Types 403, 410, 416 and 420 are representative of this group.
They contain roughly 24% chromium and 5% nickel.
Precipitation hardening stainless steels contain alloying additions such as aluminum. This allows them to be hardened by a solution and aging heat treatment.
They are further classified into sub groups as martensitic, semiaustenitic and austenitic precipitation hardening stainless steels.
They are identified as the 600-series of stainless steels (e.g., 630, 631, 660).

WELDABILITY OF STAINLESS STEELS
Stainless steels are considered to have good weldability and may be welded by several welding processes. This includes the arc welding processes, resistance welding, electron and laser beam welding, friction welding and brazing.
For any of these processes, joint surfaces and any filler metal must be clean.
The coefficient of thermal expansion for the austenitic types is 50% greater than that of carbon steel and this must be considered to minimize distortion.
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.

Cebora Torches

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.
