جوشکاری زیر آب

جوشکاری زیر آب از زمان جنگ جهانی دوم هنگامی که کشتی های خسارت دیده باید سریعاً در آب تعمیر می شدند به وجود آمد. بیرون آوردن کشتی برای تعمیر کردن آن، هم اکنون هم بسیار هزینه بر است و صرفه اقتصادی ندارد. شاید بسیاری از مردم جوشکاری زیر آب را بسیار عجیب می پندارند چون ماهیت آن را از آتش می دانند.

Here's Jennifer, doing a little shopping with pals in LA. She's carrying a bright blue Céline Phantom Cabas Bag and replica chanel handbags. Jennifer tends to prefer totes and top-handles, and Céline specifically. Jennifer carried this dark Céline Ring Bag to church just last week. She occasionally brings her kids along, but she seems to get her praise on solo more often these days, perhaps to shield the kids from the cameras. And here she is carrying the same Céline Ring Bag to a meeting in NYC earlier this year. The Ring is an extremely versatile style, but the brand seems to be intent on phasing it out. Jennifer and Céline aren't exclusive, of course. She's also partial to Chloé's new stable of styles. She carried this black leather and suede miu miu sale during a recent church outing. Here she is out shopping in NYC with a smaller, grey version of the Faye. If you haven't noticed by now, Jennifer is pretty dedicated to neutral hues. Speaking of, Jennifer carried this neutral leather top-handled D&G Monica Bag for one of her most recent trips to the cheap ray ban salon. Jen incorporated a dash of color into her Sunday style game with this unusual burgundy Hermès Octagone Bag with a striped strap. And finally, here's Jennifer outside of her church once again with a gorgeous black patent leather hermes outlet uk Bag. And in case you missed it, she's actually worn this outfit to church TWICE. Stars. They're just like us!
