I went to school with the foreman. He lucked out and got offered an apprenticeship after going there for work experience in 1981. He's been there ever since. [Reply]  [No Email]

The largest capacity plate rolls in N. America, 8" thick capacity cold and 12" thick hot (1650 deg's)! The articles are under newsroom and there's a picture of the 7" thick heads. There's a 100 ton overhead crane to support the rolls. Then they have their house built 3000 ton head press... Lanse, back gouging is very common on thick pressure vessels to ensure full penetration with no slag or other impurities. Shells are usually done with a root pass and sometimes a hot pass, followed by sub arc and then the the root pass is gouged out on the other side into the sound weld. Then it is filled up with sub arc. Nozzles coming out the side are usually all done with stick but flux-core may be used more now. They are tacked in place and often braced so they don't move. Then they are welded on the inside and back gouged from the outside into the sound weld. Even after gouging, you have to clean it up real nice with a grinder to get rid of left over carbon. Even though there is about a 30 deg. bevel to get full penetration, it can be trick getting 100% penetration into the weld done from the inside. [Reply]  [No Email]

It won't take you long to learn what to look for when carbon arcing. A grinder will cover up things, where a carbon arc will open them right up so you can see the bad things more easily.

Even the slightest bit of hardfacing would take forever to grind off. Another big advantage to gouging is doing repairs. It will show cracks that could be very hard to find by grinding. It's also a lot faster. [Reply]  [No Email]
