When you are welding on something half the shop has been machining on for a couple of months you dont have any room for mistakes. It had to be done right the first and only time. A lot of people get real shakey when they find out the cost of the part in frount of them. Big difference between production and developement work. Inconel the hardest because its dirty. Platinium a real pleasure clean and smooth. A lot of our work was done under a microscope. Also used a lot of gold nickle solder. Some soldering was harder to do than the welds. Contamination could give u problems there to.
