4.2.4 Welding

a) For Manual Metal Arc (MMA) welding, type 309L electrodes are recommended for welding 3CR12 steel, although E308L and E316L may also be used.




Revision: 0

Page: 10 of 35




b) For Tungsten Inert Gas (TIG), Metal Inert Gas (MIG) and Plasma Arc Welding (PAW), the recommended welding consumables are AWS A5.9 ER309L, ER308L or ER316L.

c) When welding stainless steel studs, bolts or nuts onto 3CR12 steel, it is recommended that the weld consumable shall be the AWS class 309L to avoid excessive weld metal dilution.

d) Where the manufacturer is using stud welding onto 3CR12 steel, then 304L stainless steel studs shall be used.

e) Spot-welding (resistance welding) shall only be used on parts of the kiosk that are not directly in contact with the outside atmosphere.

4.2.5 Post-weld cleaning (pickling and passivation)

a) To prevent corrosion at the welded areas, it is necessary to remove all traces of discolouration and scale from the welded areas. This shall be done chemically through pickling and passivating.

b) Chemical cleaning or pickling of 3CR12 steel shall be carried out using formulations based on Nitric (HNO3) and Hydrofluoric (HF) acids designed specifically for 3CR12 steel. Dipping is the preferred method for applying the chemicals. Pickling formulations are aggressive towards 3CR12 steel and pickling shall be supervised to ensure that exposure periods are no longer than the minimum required to remove discolouration. Thorough washing with copious amounts of clean cold water is required after pickling to remove all traces of the acids used.

c) Passivation of 3CR12 steel shall be carried out within as short a period after post-weld cleaning as possible. A solution made up of 10% to 20% HNO3: balance H2O (water) is suitable for passivating 3CR12 steel. Dipping is the preferred method for applying the solution. The solution shall not be allowed to dry on the steel surface, as staining can result. Thorough washing with clean, cold water after passivation is required.

d) The kiosk shall be degreased prior to pickling and passivation.

4.2.6 Powder-coating

a) Before powder-coating can take place, it is very important to ensure that there is no oil present on the kiosk. The kiosk shall be degreased before powder-coating.

b) The inner plate shall be powder-coated with white epoxy-polyester powder ([4] SANS 1091 colour code 69-0135) to ensure a coating thickness of between 60 μm and 80 μm.

c) The kiosk (box, roof and base) shall be powder-coated with light navy grey polyester powder ([4] SANS 1091 colour code G35) and the thickness shall be between 60 μm and 80 μm.

4.2.7 Shipping

a) Each kiosk shall be wrapped in bubble wrap or cardboard before shipping to Eskom stores.

b) Mounting nuts and bolts shall be suitably protected to protect them from damage during transport.

4.3 Meter kiosk electrical equipment

4.3.1 General

a) All equipment used within the kiosk (meters, circuit-breakers and terminals) shall be touch-safe, i.e. have enclosed terminals, recessed screws, etc. They shall comply with clause 8.2 of [1] IEC 60898, which states all the requirements for equipment to be touch-safe.
