, BiHave a read of this mite answer a few of your questions. Also note all remarks are made from top tier blue chip companies. You can't get better results than that.
According to Brett Jago, Bilfinger’s Production Supervisor, “The K-TIG system has created a huge range of opportunities for us. It provides us with substantial cost savings across the board. We’ll be using it for everything in range. This is extremely significant new technology, and an enormous leap forward in productivity. We’re glad we got in early.”
The K-TIG controller ensures repeatability & conormity to our weld certifications. Even an inexperienced operator can simply select which program to use, and it will weld exactly how you expect it to.Brett Jago, Production Supervisor, Bilfinger
K-TIG’s ability to virtually eliminate wire consumables has had a dramatic impact on the cost of each weld.Brett Jago, Production Supervisor, Bilfinge
With only one pass involved in most applications, there’s greatly reduced gas consumption. We’ve seen gas reductions of up to 96%.Attila Szabo, Principal Joining Engineer, GE
K-TIG welding is a new productivity benchmark. It sets an entirely new bar for what can be achieved with an arc welding system. The speed, penetration, quality and overall savings generated by the process are extraordinary. Attila Szabo, Principal Joining Engineer, GE
According to Atilla Szabo, GE’s Principal Joining Engineer, “This process will make fabrication more cost effective in developed economies such as the US. The 90+ percent reduction in welding time and gas consumption, the elimination of edge bevelling and the elimination – or near elimination - of wire consumables are of tremendous significance to fabricators and go straight to the bottom line,”
The results speak for them selfs..
check out the web page and try get download some case study's the result are unbelievable..Nothing compares to K-TIG it's in a league of its own..
http://www.k-tig.com/applications-aerospacewebsite is very good a lot of information that can answer a lot of questions for people new to the space.
