The individual beads do not seem too humped up (convex) however the valleys between the beads take away from the appearance. Concentrate on bead placement during the cap. Forget about how many beads you are going to cap with. Try to maintain a smooth transition where the toes of each bead tie into t...

They were used commonly in Black Liquor Recover boilers in paper mills. I never encountered the need fir a window weld in a power boiler however my experience is only mine.

In the cases where I was involved, they were always composite tubes. 300 series ss over SA210-A1 core.

Mike, Whenever possible they try to avoid window welds. In tangent tube furnaces with welded membrane, window welds are necessary. Than furnace design is not common. The tubes I was spoken of were those where you could only weld one side at a time. Sometimes scaffold or boiler configuration prevents...

I tested a group of brothers from Texas on a new recovery boiler job back in the 90's. I told them where the gas was and the toolroom and to get setup while I went to look at something. I came back a bit later and they were standing around with 4 or 5 tig rigs on the table and mad because they thoug...

@txweld Here is something I wrote a few years ago. I am by no means the authority on all things welding, but it may give you some things to think about. https://weldingclassroom.wordpress.com/ ... is-needed/

Looks like a ton of fun. The ones where you can get someone on both sides are usually better than the ones that have to be airbagged and welded one side at a time. Good fun though.

Congratulations Fredy!

Yes. I think the carbon content is the biggest issue as opposed to the method of manufacture. Cast Steel with .020 carbon will weld essentially just like plate, sheet, strip etc... of the same carbon equivalency. Of course with a casting there may be issues with part geometry that could cause diffic...

Cast steel is welded just like plain carbon steel of the same composition. "Casting" of carbon steel is no different than what happens as your weld metal freezes. Sometimes because of the complex configuration of some cast steels and possible variations in chemistry, cracking can be ann is...

The AC Balance may cause balling or blunting of the electrode during the DC+ side of the cycle. If you are running with your balance towards the electrode negative side, you may be able to keep the electrode nearly sharp. As you turn the balance towards the + side, the electrode will ball up more. T...

Welcome to the forum.

It depends upon which polarity you are running with your FCAW setup.

GMAW Aluminum is run on DCRP in all cases in which I have welded it.

The Entire OSHA standard is available online which can allow you to search additional information, interpretations, and other information. If you have the paper version with you, the para below may help you . 1910.27(b)(6) "Welding." All welding shall be in accordance with the "Code f...

6010 root and boiler pressure? Yes. There is no "Code Restriction" that I am aware of. Do you know of one ? Though it may not be the "common" way of welding a root pass in, its effective, efficient, and suitable for many applications. Best??? Maybe not always. But it works in ma...

Here is a great article by a man extremely familiar with the ASME Codes as they related to welding. May not fully answer your questions, but may give you a little more info to chew on. http://www.thefabricator.com/article/te ... adiography

There is no difference in acceptance criteria based upon the process or filler metals in B31.1. Typically rounded indication acceptance criteria is a percentage of wall thickness. https://law.resource.org/pub/us/code/ibr/asme.b31.1.2007.pdf see para 136.4.5 which refers the acceptance criteria for r...

Mig welding as with many other processes can sometimes have a wide variety of employment option. The industry sector and the products will often dictate how much skill you need or will gain while employed. Someone running 1" welds on yard art will require ans gain less skill than someone buildi...

Some quizzes I have used in the past that may be of interest. Only a few questions. One is a static HTML page so someone could copy and modify if for there own use. The other is made in a CMS called Concrete 5 http://weldertraining.org/index.php/welding-core-knowledge/quiz-number-1/ http://www.weldi...

You will always work for those who are willing to hire you. You can increase that number by growing your skills, knowledge and experience. Not every welding job is gonna be the dream job. Some people always want more. The more may be money, challenges, responsibility, or who knows what. There are tr...

Thanks for the comments. Everyone has so many varied experiences,how they learned to weld, jobs, people they have met, companies they like and don't like etc... I would imagine that one thing many of us have in common is enjoying what we do. Booomer, I have probably turned a few people off by my ent...

Welcome to the forum.

As a Southerner I have to tell you that The Cape is the only place north of Tennessee that I have ever worked and considered going back to to visit.

Have a good day.

A good video. I will definitely be referring students to it. This position can be a pain because of bead contour and placement. A note on the 2G position, For structural welders (D1.1) this position is not required to be tested in if a 3G/4G is performed. For ASME Sec IX, 2G/3G/4G is required. Great...

Everyone will always have to do things based on taking care of core "needs". If I have to do something besides welding to support my family, so be it. But I work towards being able to not only take care of my needs with money but also grow towards being able to do what I enjoy. One thing I...

Well Deserved and more.

Jody, I sincerely think you have contributed more to welding training than any single organization.

Congratulations on your decision to get into welding. I have worked in a few different industries. I have done OK in those. At no time did my personality have to change. I show up, with skills, work ethic, and desire to be a profit to the people who pay me. Sometimes I have done a good job, sometime...
