29、 ISO 16433:2007 (E)51 Scope This International Standard specifies requirements for resistance seam welding in the fabrication of assemblies of uncoated and metallic coated low carbon steel comprising two sheets of metal, where the maximum single sheet thickness of components to be welded is within t
30、he range 0,4 mm to 3 mm for the following materials: uncoated steels; hot-dip zinc or iron-zinc alloy (galvannealed) coated steel; electrolytic zinc, zinc-iron, or zinc-nickel coated steel; aluminium coated steel; zinc-aluminium coated steel. Organic-coated or primer-coated steels are not covered by
31、 this International Standard. Guidelines for the design of appropriate seam welding equipment and welding conditions are given in Annexes A and B. These are for guidance only and may need to be adapted to suit the specified service conditions of the fabrication, prevailing production conditions, typ
32、e of welding equipment, mechanical and electrical characteristics of the welding machine, electrode configuration, and material. These requirements shall be taken from the relevant welding procedure specification for the application or procedure, where these exist. 2 Normative references The followi

38、.1 continuous-current seam welding use of a continuous-current waveform to make a weld NOTE A continuous weld nugget is formed along the weld seam. 3.2 interrupted-current seam welding use of a current program comprising two or more pulses of current (commonly known as “on-time”) separated by a pre-
39、set cool time (commonly known as “off-time”) NOTE A weld nugget is produced during each pulse. 3.3 tread width width of the electrode face which is in contact with the work piece NOTE Sometimes this is called electrode face width. 4 Materials 4.1 Form The steel shall be flat rolled, in coils or cut
40、to length, and shall be free of all harmful imperfections. 4.2 Steel grades A partial list of steel grades to which this International Standard is applicable is given in Annex C. 4.3 Surface conditions Prior to welding, all surfaces of components to be seam welded shall be free of contaminants such
41、as grease, scale, corrosion products, paint, dirt or excessive pitting. This condition shall be maintained until the welding process is completed. Uncoated hot-rolled steel shall be in the pickled condition. Certain surface treatments, such as the application of paint primers, rust preventions, and
42、oils may be applied before welding, provided that the coating is uniform in thickness and it has been demonstrated that consistent welds, conforming to this International Standard, can be obtained. Excessive use of surface pre-treatments may adversely affect electrode life and should therefore be av
43、oided. Coated steels can be supplied with a chromate or phosphate passivation treatment. Phosphated mild steel may be used in certain applications. These materials can be resistance seam welded, although the welding parameters outlined in Annex B may require appropriate adjustment. Generally, only t
44、hin phosphate pre-treatment of steel is acceptable prior to seam welding. EN ISO 16433:2007 (E)75 Component design and manufacture 5.1 Component design Components shall be designed and manufactured to provide adequate flange widths, free from potentially harmful physical deformations and internal st
45、resses, and which can accommodate the weld seam. The flange width should also provide proper access for the electrodes and any necessary tooling. Account shall be taken of the degree of mechanization for guiding the components along the weld path/track during the welding process. The procedure shall
46、 include provision for reviewing the design as a result of tests, whether compliance with this International Standard is achievable or not. The design of the assembly to be seam welded shall take into account the process requirements specified in Clause 6, and the process variation appropriate to th
47、e application. The shape of both components shall be such that there is proper contact over the entire weld path. The weld size (seam width) and the distance (edge distance) from the centre of the weld to the nearest edge of the components shall comply with the process requirements given in Clause 6
48、. NOTE Reducing the edge distance below the recommended values can affect weld quality and reduce the operating tolerances. In this case, the nominal weld size may need to be specified below the value given in 9.2.1, and allowance for a lower weld strength made in the design. The pitch between two p
49、arallel seam welds, i.e., the centre-to-centre distance of the seam welds, shall not be less than 16 sheet thickness (t) and preferably larger. When seam welding sheets up to, and including, t = 1,5 mm, the inter-weld pitch shall therefore approximate to 3 We(We= tread width). To stabilize any shunting effects, this pitch shall be maintained within t 10 % over the entire length of the joint. In cases where smaller weld pitches are necessary, the weld cur
