Reply:Elvis, i've noticed a lot of great stuff coming from you, but have to ask... What kind of shop do you work in? i mean absolutly no disrespect, i am just curious... those are vastly huge pieces of pipe that i am usually seeing, and Ti? that is HUGELY expensive! i really like that you take your work very seriously. i am trying to follow the posts as closely as possible, and am happy that the teacher is so dedicated. i am really enjoying the pictures. i can't remember who said it exactly in thread one, but i agree that i never thought that looking at pictures of welds could be so enjoyable. keep up the good work. i can't wait to see how the Ti works out. i love the colorations and "rainbow effect" that the weld leaves.later,Andy
Reply:aczeller....Preliminarily (is that a word?), I work in and have usually worked in a "code shop". Back in the 80's I completed 2 years of a pipefitter/welder apprenticeship but relocated before I could finish. Most companys I have worked for fabricate pressure vessels, and related piping systems. It is not unusual for me to work with flanges 36" in diameter, or a shell 12' in diameter. Most work I've done is subject to AWS or ASME quality control which can require x-ray testing in varying percentages. Chlorine, phosgene (etc) vessels (lethal service) are common. Many times we will get a contract requiring exotic metals, such as titanium. Recently I welded a portion of a fan made of inconel which had a material cost of $10,000. It has been mentioned that excess discoloration on Ti is unacceptable and that is true. The rainbow effect may look nice, but it is contamination and must be minimized (we finally built a purge chamber to fit the weldment). I have certified on Ti, and that particular job is finished and it may be some time before I see Ti again. Unfortunately, I have no pix of the finished product but on the plus side, it wasn't sent back. ELVISLast edited by ElvisW; 10-12-2007 at 04:41 AM.
Reply:i see. thanks for the insight. i used to work for Northern Natural Gas (16,600 miles of natural gas pipeline from 2" through 36") and every weld that was completed had to be 100% X-rayed (or other approved testing method), so i can understand the code aspect. it sounds very interesting (your fab shop). i think i woudl really enjoy that experience. any pointers for getting into the welding industry?thanks!AndyP.S. my screen name is ACZeller... short for Andrew Christopher Zeller.
Reply:aczeller...if you are not already a welder.I myself YEARS back enrolled in a welding program at a vocational high school. I was taught the basics and I do mean BASICS. I give full credit for my abilities to my co-workers over the years who either taught me the correct procedures, or yelled at me for doing them wrong. Experience was my best teacher. A welding program is a must though for a beginner and should not be hard to find in most areas. They will give you a taste of a variety of welding procedures but will probably not focus on any one in particular. After you get your first welding job, your skills will increase. Especially if you ask alot of questions and spend your lunch breaks experimenting with procedures you don't come in contact with in your daily job. Welder is not at the top of the list these days as an occupation desired by younger people. Mouse clicker probably rates higher. It can be hard dirty work and the numbers are diminishing. But that's why we are here. To help others if we can become more proficient at welding by sharing knowledge/experience. WeldingWeb is a great place to learn new tricks but you must have the tools (machines) necessary to apply them. Enroll in a welding course and I am confident you will easily find a welding job and help fill the void.ELVISLast edited by ElvisW; 10-13-2007 at 10:59 AM.

Reply:Back...I tried signing in some months ago and could not, so I gave up. I must have been doing something wrong.To what degree I'm back is questionable at this time. Sorry for leavin ya'll hangin'.At this time things are slow at my shop and being the part timer I am the first to be asked to stay home. The economy I guess. So for now it's music only for me. But this has happened in the past and never lasts longer than a month or two. I intend to finish what I have started but can only answer questions or provide text at this time. Feel free. I was rather shocked upon returning to find this a well viewed thread. I can only say for like the hundredth time, thanks for the interest. And thanks to management for keeping this thread open for me to complete someday.ElvisLast edited by ElvisW; 06-01-2009 at 01:56 PM.
