Thank you for your reply. "Stick Welding" is slang in the welding business, at least in my region and the most technical word we've ever used for it is arc welding. I did some welding for about 3 years and had a state certification. My comments were based on the current ship building industry http://www.appliedthermalsciences.com/Laser_Welding/Laser_Welding.html, and not intended to state that conventional means of welding will be abandoned in the future. I think you're right in stating the trailer is meant to be purely figurative and illustrative, which is the real problem I have with it. However it is just a teaser, and theres no guarantee that scene will even appear int the film. My comments were purely intended to nitpick based on my irrational hatred of Hollywoood and distrust of JJ .
