Can some one explain to me the difference between laser and Tig welding. I know the technical difference but what are some pros and cons? Is Laser welding the new tig welding? If Laser can weld thin/thick and produces stronger more cosmetic welds isn't tig welding going to be slowly phased out? From the limited knowledge i have about laser, the only major setback right now is the cost of machine. As technology advances the price point will slowly decline allowing it into the hands of consumers? Is there some major negative with regards to laser which i am overlooking?

Which companies are major players in the laser welding field?
