Nickle weld engine block
If you're planning to use a nickel weld to fix a cracked engine block, think again. Electric welding on an assembled engine should never be attempted. It simply breaks every rule for successfully welding cast iron, which will always require high temperature preheat of over 1,000°F. It is impossible to create a stress-free, leak-proof weld with even a preheat as high as 600°F, which you cannot do on an assembled engine anyway. If anyone tells you differently, they just don't know what they are talking about.
If you own a Cummins Diesel 5.9-liter engine with the number 53 cast on the side, you may face a serious problem. There are a number of these engines installed in vehicles between 1999 and 2001 that develop cracks.
The pros at LOCK-N-STITCH Inc., however, have used their 30 years in the business of cast iron oven welding and metal stitching to find the best solution.
The most effective solution does not involve any type of weld at all. Instead, LOCK-N-STITCH Inc. has used their patented repair solution of metal stitching and their new reinforcing bracket for the job, fixing the problem at the root.
Even if you're not prepared to do it right the first time, make sure you don't do it wrong the first time. A nickel or even a braze weld will further damage the block and even prevent stitching the crack later. At that point, you'll be looking at a full replacement of the engine block.
