Just a curiosity ... but why did you choose to study welding instead of another discipline?

My gut feeling was that you were going to do okay ... but to ward off the evil eye ... it is better to not say anything.
So now ... you can share some of your tips and tricks accumulated over all those years.

I'm going to be testing on Hastalloy C276 soon and would like any advice, tricks and tips to welding this metal. Its going to be a pipe test 6g on a sch 80 2". I have been welding for nine years and have mastered Stainless, carbon steel, cast iron and have a lil experience with aluminum. Any a...

IronManJay. One aspect of welding is explaining how the weld was performed ... which is essentially a welding procedure. Welds that need to conform to Client's specification, to the Fabricator's procedures, and to Codes ... will require a procedure. A procedure has a number of welding variables that...

correct me if im wrong but isnt hydrogen highly unstable, the same reason why automobile companies wont use hydrogen to power the automobiles instead of gas. by compressing that into a gas cylinder would make the risk even higher if something was to happen inside of a shop? say if something happene...

i am confused with the whole idea of people adding oxygen to tank mixtures, doesnt that contaminate welds just as if wind is to blow away the shield? i have never seen any mixture in my area include oxygen. all we can get is argon,co2, helium for welding. but for cutting we can get full tanks of ox...

Prompt38. The whole idea is to not let air reach your puddle while welding. If you have room to weld onto the inside surface of the boiler, you may need to repeat the process from the inside. Slightly filing or grinding down along the crack to remove oxides and to reach clean metal, and then fill it...

I ended up buying a Dynasty 200DX and been playing around with all the buttons and what not. I realized that I've been pulsing (1pps, 60%on 40%background @120A for .120' wall DOM tube) for the past 2 days on all the steel I've welded. I am curious if I am making this a bad habit? I know pulsing can...

Do you have the brand name for the rod?
Years ago Kobe (if I recall correctly) used to make something similar that would leave a glass like surface on the internal surface of the weld and protect it from oxidation.

Hi all. My first time tig welding and I seemed to have messed up big time. I was trying to weld a 304 threaded shaft onto a 304 stainless boiler but my lack of experience and practice led me to make cracks/holes on the surface of the boiler. The boiler is about 3/32" to 1/8" thick. The th...

i have 90/10 argon co2, 75/25 argon co2 and i have pure argon. i use pure argon for my tig machine, my 90/10 and 75/25 are both on my 220 mig welder, i was curious, if you use 98/2 argon co2 then why dont you just as well run pure argon? i wasnt sure if that would work or not. with that little of c...

Are you learning a lot?
Sometimes money is secondary to a job that is rewarding.

Chadwarden. 6010 rod. If there is excessive weld metal buildup at the extremities of the tack, then a quick hit of the grinder is recommended. For a restart, the quicker the rod is changed and restarted, the better. This allows the restart to begin with the weld metal still hot. Normally it is not n...

What is the manufacturer and model of your regulator?

Otto Nobedder. About twenty-five years ago, my failure analysis instructor, drilled into us to not 'guess' the cause of the failure when starting to investigate. He keep telling us, if you start with a probable cause, you will almost always prove yourself right. He said even very good metallurgists ...

Otto Nobedder. When you wrote that you saw three 'signatures', i thought you meant that you compared the three welds and noted that three different welders had done them. Darn ... I went back and started looking at those welds and tried to understand the differences that you had noticed. Then after ...

Regy_boy. Do not know about the UK, but many constructors/fabricators around the world will require you to take a test weld as per the contractual code of the project that you will be welding on. So if that is the case, then yes, the employer pays the cost of qualification. Depending upon the contra...

Could the inverter welding machine that is not 'generator safe', be protected by put an adjustable 'breaker' between the generator and the welding machine connections? Perhaps breaker would be similar to the components that are within the 'generator safe' inverter machines.

It is a relief knowing that you will be working in your shop for this project.
While following your string evolve over these weeks, for some reason or another, I was imagining you having to do the work on site.

Keep us informed.

A very simplified overview of some major codes are at the attached link:

Are developing the welding skills on plates as well as piping?
Have you started to learn stick welding?

Robertj. Even though you are new to welding, you probably know that welding can be done in different positions, in example when the pieces are flat, vertical, overhead ... let's say out of position. Each position has its difficulties. Perhaps the easiest for a beginner is the flat position of the wo...

"Network Simulation" ... I had to look that one up.
A long shot, but have you seen any overlap with welding and network simulation?

So what type of hobby projects do you weld?
