Yes, I understand. I am a certified TIG/MIG operator, and I myself have 
welded cast iron, without incident, using the procedures you described. One 
thing I like to do, is after finishing the bead, I set the oven to around 450 
degrees, and place the part in it, every 15 mins, I lower the oven temp by 50 
degrees, until it gets turned off, this allows the metal to cool SLOWLY, 
allowing proper heat-treating.... As Jorgen stated, welded cast will be as 
good or better than original, if done properly. Often, people that are 
uniformed will spread rumours, based on here-say. Heck, its even possible to 
weld steel to aluminum, with the right rod! Happy Audi-ing.
