35、SO 1071:2003), which has been technically revised.DIN EN ISO 1071:2016-05 EN ISO 1071:2015 (E)4 IntroductionThis International Standard classifies welding consumables for fusion welding of various types of unalloyed cast irons.Applications for welding consumables classified to this International Sta
36、ndard: production welding, that means welding of cast materials during the process of production. In that way, the quality of the casting shall be ensured in accordance with the guaranteed properties and to the requirements of the application; repair welding of castings which are damaged during serv
37、ice; welding for construction purposes where cast irons are joined to themselves or to other ferrous or non-ferrous metals.The following methods are used for the welding of cast irons: using a welding consumable which produces a weld metal similar to the parent metal. High preheating is required (ty
38、pical temperature range 550 C to 650 C); using a welding consumable which produces a weld metal dissimilar to the parent metal. No or only low preheating is required.This International Standard contains different types of welding consumables because the chemical composition of welding rods and wire
39、electrodes, as well as the all-weld metal of the corresponding covered electrodes and tubular cored electrodes, is similar.Additionally, to the welding consumables specified in this International Standard, consumables classified to other standards can be used (see Annex A).DIN EN ISO 1071:2016-05 EN
40、 ISO 1071:2015 (E)5 1 ScopeThis International Standard specifies requirements for classification of covered electrodes for manual metal arc welding, wire electrodes for metal arc welding, tubular cored electrodes for metal arc welding with and without a gas shield, rods for TIG-welding, and rods for
41、 oxy-fuel gas welding of unalloyed cast irons. Classification is based on the chemical composition of wires and rods and on the all-weld metal deposit for tubular cored and covered electrodes.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this docum
