I just started practicing for TIG open root. I am having trouble, so, I thought I would ask for some help from you guys with experience. What size is your landing and root gap? Whats your bevel angle at that? What amperage and filler metal size are you using? are you walking or whipping? What cup si...

Im practicing downhill 6G. My filler/cover pass I am using 7010 rod. I am encountering quite a bit of spatter when I am finished. Its not sever but it is present, especially on the top of the pipe. Will inspectors in the field have a policy against spatter? Is there any method of spatter control I c...

To all the engineers in here, I have always operated under print specs, which often come stapled with a WPS that includes preheat temperatures, etc.. But I have been curious to know, what are the "rules" (loosely worded) to determine what needs preheat and to what temperature. Of course, t...

How does one obtain a TWIC card?

I have always wondered about the pancake hood. Why use it over other hoods? What is the purpose, other than shoving your head between the ground and a pipe or in a tight spot? Is there really any benefit to using a pancake over other hoods?

Any welders on this forum currently or previously welding in west Texas? Is there still plenty of work to be had? Is it difficult to locate housing? Who are the contractors to contact, and who to avoid?

Thanks...

Wasn't something like this just posted? Yesterday I think. It's interesting. A lot were saying Tig was very common even in the older days. Field work will still be more SMAW. Think of the elements.

6010 root pass on open root pipe is standard and has been taught for many years. This is followed by a 7018 fill and cap uphill or 7010/8010 downhill. (Most typical) I have noticed over the past years many employers and engineers running a tig root with a flux core fill/cap, 7018 or 7010/8010 fill/c...

I run mine:
3/32 - 50-55 amps
1/8 - 75-80 amps
5/32 - 80-90 amps

I run on a crisp setting at +2 as well.

Hope this helps!

Im in SLC, UT. There are 2 major Chevron refineries here as well as Lauren Engineering (A company that specializes in the energy industry, refurbishing refineries and erecting new facilities around the globe). I know for a fact that all shop fabricated parts built by Lauren is Tig root and Tig out. ...

Very nice! Looks good. Are you going to bend test?

Here's my Invertec v250-s, but others are different.

Thanks! This helps a lot!

What is the actual difference? Like what happens differently with each setting? Sent from my SM-G900R4 using Tapatalk Crisp is 100% arc force. It digs a whole lot more. Soft setting will "soften" the arc force. I have noticed if I have crisp on while I do my 7018 fill pass I am more likel...

Hi all, Question, Im using a Lincoln machine at school, training for pipe, uphill and down. I have never used a machine with soft/crisp arc settings before. I have noticed quite a difference when switching between the two. But I am curious to know, when is the best time to use one or the other? For ...

Thanks.

Ill get some pics up at lunch.

Any info on where I can find specs/WPS for a branch test?

For sure!

I am currently in Salt Lake City, Utah.

I am mobile and willing to go just about anywhere, especially Alaska. Preference does not matter so much at this time. I have nothing tying me down and more seek experience than geographical location.

Im Jake. I am experienced in custom fabrication over the past 10 years but recently decided to go back to school specifically to learn pipe. My past as a welder/fabricator has helped greatly in my training but I am more interested in getting my hands dirty on actual projects, as a learning opportuni...

Thanks for the info. I dont have access to 1/8 7010 rods. At the moment all I have on hand is 5/32. Im "warming up" on plate (yesterday and today), 3/8 thickness, 8" joint, 30 degree bevel/60 degree angle, 1/8 land, 3G position, and trying to get the feel of downhill. Its very differe...

I have some questions on downhill procedure. Im practicing for 6G cross country pipe. All passes downhill: root, fill, cap. From what I have been told by the instructor at school, root is 6010 (typical) but filler and cap are 7010. I am curious to know, what are the parameters most commonly used in ...

[/quote] Jake, Maybe you should have found a job before quitting one? :) ;) If I am understanding your question correctly, you want to do 6G but are practicing on a 3G plate. While that I good, you need to get to a 6G practice piece as soon as you can. Running a 6010 straight down is a little differ...

Hey I wanted to ask you for your opinions on Pipeline Welding. Right now Im in college and thinking of going to the Tulsa Welding School to do the Pro welding program in hopes of becoming a pipeline welder. My parents work for a natural gas company and are pushing me to become a welder on the pipel...

Justjake85, Welcome to the forum. How about a introduction and a little more information. What material, pipe or plate, rod etc? -Jonathan No problem. I am training to pass 6G test. I hope to go out to the oil field after I am confident with my training. I have been welding MIG, TIG, Spray Arc and ...

I am practicing for a pipe test. I have the uphill down. I am struggling with the downhill. I am noticing my slag running through my puddle and its throwing of my arc, my visibility, and my final bead. Any suggestions would be appreciated.
