21、t methods according to EN 969. Applications for welding consumables classified to this standard: production welding, that means welding of cast materials during the process of production. In that way the quality of the casting shall be ensured according to the guaranteed properties and to the requir
22、ements of the application; repair welding of castings which are damaged during service; welding for construction purposes, where cast irons are joined to themselves or to other ferrous or non-ferrous metals. Two different methods are used for the welding of cast irons: using a welding consumable whi

High preheating is required (typical 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 standard contains the different types of we

Additionally to the welding consumables specified in this standard, consumables classified to other st
