The English translation is believed to be accurate. In case of discrepancies the German version shall govern. Page 2 VW 011 06-1: 2004-07 1 Scope This standard applies to the design, layout and quality assurance of arc-welded sheet steel joints which are predominantly subject to dynamic loads. It comprises the following procedures according to DIN EN ISO 4063: Reference no. Method Code 131 Metal inert-gas welding MIG 135 Metal active-gas welding MAG 141 Tungsten inert-gas welding TIG for: butt and fillet welds, lap welds, plug welds and special weld types of: bright uncoated and coated sheet steel as well as of both high-alloyed steels and premium steels; for examples see Section 4.1; Workpiece thickness 0.5 mm to 6 mm with: test characteristics of quality level B (high requirement) according to DIN EN ISO 5817, see also DVS specification 0705. All fusion-welded joints to which this scope is not applicable require the clarification of the responsible engineering departments. Special measures made necessary because of the component, e.g. change to the quality level for specific imperfections, are permissible and shall be entered in the drawing. 2 Abbreviations and definitions 2.1 Abbreviations a Calculated throat thickness mm f 1,2Penetrations on sheets 1 and 2 mm f L Penetration length mm f StPenetration at the face surface mm or % (of face surface) F i Joining plane - h Gap size mm l Throat length mm L Length mm s Throat thickness mm s 1,2Throat thickness with respect to sheets 1 and 2 mm s Nsmallest common throat thickness mm t 1Thickness of sheet 1 mm t 2 Thickness of sheet 2 mm HAZ Heat-affected zone - St Sum total of sheet thicknesses mm ? Diameter mm Page 3 VW 011 06-1: 2004-07 2.2 Definitions FüThe following definitions are valid for the application of this standard: 2.2.1 Weld joint Joint created by fusion welding. It comprises the weld, fusion line, heat-affected zone and unaffected base material (Figure 1). 1 2 3 4 Legend: 1 = weld 2 = heat-affected zone 3 = fusion line, fusion zone 4 = unaffected base material Figure 1 – Fusion weld joint NOTE Weld and fusion line may be identical. 2.2.1.1 Weld The area where the workpiece(s) is/are joined at the weld joint. The weld comprises the base material and/or the filler metal. 2.2.1.2 Fusion line Borderline between the base metal and/or filler material melted during welding and the metal that remains solid. 2.2.1.3 Weld metal Material that solidified after welding, comprising either the base material or filler metal and base material. Some elements in the weld metal can come from casings and/or accessory materials (DIN ISO 857-1). 2.2.1.4 Heat-affected zone HAZ Area of the base material that remained solid, but, due to the energy applied during welding, experienced microstructural changes related to temperature. Page 4 VW 011 06-1: 2004-07 2.2.1.5 Unaffected base material Area of the base material that experienced no evident microstructural changes as a result of the energy applied during welding. 2.2.2 Same types of material Materials which do not differ significantly in terms of their chemical composition and their suitability for welding (DIN 8528-1). 2.2.3 Different types of material Materials which differ significantly in terms of their chemical composition and their suitability for welding. 3 Gas-shielded arc welding procedure Gas-shielded arc welding is a form of fusion welding. An electrical arc is used as the heat source. It burns between the electrode and the workpiece. In this process, the arc and the weld pool are protected from the atmosphere by a shield of protective gas. The classification into the following procedures depends on the electrode type: 3.1 Tungsten inert-gas welding (TIG) In this procedure, an arc is ignited between a non-consumable tungsten electrode and the workpiece. Argon, helium, mixtures of both and sometimes added active gases, are used to form the protective atmosphere. The filler metal is (as in the case of gas welding) fed from the side. 3.2 Gas-shielded metal arc welding (MIG/MAG) In this procedure, an arc is ignited between the melting end of the wire electrode (filler metal) and the workpiece. The welding current flows via sliding contacts in the electric current guide of the gun to the wire electrode. When inert gases (low-activity gases, e.g. noble gases such as argon, helium or mixtures of both) are used as protective atmosphere, this is called metal inert-gas welding (MIG). When active gases are used (e.g. CO 2 , or mixtures containing CO 2 , or, in some cases, mixtures of CO 2and oxygen), this is called metal active-gas welding (MAG). This procedure is used to weld unalloyed and low-alloy steels. Page 5 VW 011 06-1: 2004-07 4 General requirements Welds that are subject to mandatory documentation shall be evaluated according to the relevant type-specific and/or component-specific test specifications (PV). Deviations with respect to the specified weld geometries and weld layouts shall be detailed in the drawing and verified by testing. They shall be described in test specifications (PV). Further requirements with respect to gas-shielded arc welding are contained in the following documents: VW 011 06-2 Shielded Arc Welding - Rework on Sheet Metal Connections VW 011 06-3 Gas-Shielded Arc Welding – Part 3: Al Welded Joints VW 011 42 Welded Seam Repairs on Aluminum Structures – Product Evaluation and Notes on Procedure When creating arc-welded sheet steel joints, the greatest possible design strength in accordance with the design goal must be realized while also ensuring sufficient reliability and a favorable cost/quality ratio. For this purpose, every weld joint must be suitable for welding, i.e. the dimensions of the welding equipment and the accessibility of the weld according to DVS 0929 must be taken into consideration for design. Weldability for service of a sheet steel joint is given if the component, on the basis of its design (Section 4.2) and with the material used (Section 4.1), remains functional (Section 4.3) under the intended operating stresses (Figure 2).

The respective type of joint is determined by the arrangement of the parts with respect to each other (extension, reinforcement, branching), see Table 1. Table 1 – Joint types (DIN EN 12345) No. Type of joint Position of parts Description 1 Butt joint The parts lie in the same plane and touch against each other end to end 2 Edge joint The parts lie on top of one another in parallel, e.g. in explosive cladding 3 Lap joint The parts lie in parallel on top of one another and overlap. 4 T-joint The parts meet at right angles (T- shaped) and lie on top of one another 5 Double T-joint Two parts lying in the same plane meet on a third part that lies between them at right angles (forming a double T shape) 6 Bevel joint One part meets the other at an angle. 7 Corner joint The edges of two parts meet at an angle of more than 30 (corner) 8 Front joint The edges of two parts meet at an angle of 0° to 30° 9 Multiple joint Three or more parts meet at any angle 10 Cross joint Two parts, e.g. wires, lie on top of one another in a cross shape Page 9 VW 011 06-1: 2004-07 4.2.2 Weld types The weld type is determined by the following: Type of weld joint Type and scope of preparation, e.g. gap optimization (see DIN EN ISO 5817 and DIN EN ISO 9692-1) Material Welding method. 4.2.2.1 Fillet weld The parts lie in two planes with respect to one another, form a fillet joint and are joined by welding. It is possible to differentiate between a fillet weld (Figures 3 and 5) and a double fillet weld (Figure 4) with and without edge preparation Figure 3 - Fillet weld on T-joint Figure 4 – Double fillet weld on T-joint Figure 5 - Fillet weld on bevel joint without edge preparation 4.2.2.2 Square butt weld on butt joint, flanged weld The parts lie in one plane, form a gap and are joined by welding, see Figures
