[QUOTE="Welding Supplies Direct, post: 320254, member: 4292"] The electrodes quoted are for dissimilar electrodes the cast-iron are £44.00 per kg. Welding cast-iron as apose to cast-steel requires the following: 1. Preheat . Then weld then delayed cooling 2. Weld short runs without pre heat and then stress relieve with a chipping hammer. Both methods are possible with all types of electrodes now days however you will get better results with quality electrodes but they do come at a premium. There are two types of cast-iron electrodes. 1. 60/40 2. 98% Ni If you need to know what to use and are a little unsure please give us a call on 0800 121 8802. Regards Jonathan [/QUOTE]
