Weld types explained

[Charley Davidson]

Anybody (Stan) care to describe each of the types of welds we should know how to do?
Maybe add pics of how they should look when done properly.

It's been years (high school 77) since I've been in a welding class.

I'd be interested in that too!

i dont think i understand the question.... are ya talkin about the different joint types? position? or like mig tig stick... i gotta have a lil more to go on here...lol

sorry i havent been around much lately, i try to log atleast once per day and quickly type a answer here and there, bridge building got me wicked busy right now...

Fillet, plug, lap, & so on When to use which one, stuff like that. do's & don'ts

sheesh, i hate computers! i had a 4 paragraph dilly tryin to explain it all and the stupid thing restart on me n lost it all.... so, here goes again...

next month, i will be flying out to a place to make videos of different welds in different positions using various processes on various metals. hopefully that will be the answers most are looking for. this isnt going to be easily explained without the aid of video, but i'll give it a shot...

the do's and dont's of all this...... you arent asking for much are ya???lol!

welds are broken down into pre approved joints and weldments. 1-6 either f or g... example is a 3g or 2f. the number is the position 1 being flat 2 horizontal, 3 vertical, 4 overhead, 6 is commonly pipe that is set at 45 degrees to the ground, so that when its welded, you cover all positions in a single pass... the "f" is for fillet. the fillet is typically a "t" joint. the fillet is guaged by toe, throat, height. toe is the prtrusion at the bottom, throat is the thickness int he center and height is the (you guessed it, the height of the weld).... the "g" stands for groove... typically a butt joint. bevel the edges and when placed together, you have a groove to fill.

testing is commonly done with a groove test, because its harder to get complete fusion while maintaining bead characteristics.

i think thats gonna answer your question for that....... i think....

now, if youre asking what process do's and donts whether it be 1f or 4g is gonna take me a month to write and explain... each stick rod is different and runs in each position differently, mig is mig, unless its aluminum, fcaw has its own lil things and tig is different again...

i would have to write down each rod and how to run it, then do the same again for solid wire mig, then again for tig, or, just wait for the videos...

as for pic's, i'll try to get some different things going, but like i said earlier, the brisge job has me completely covered up right now

Clear as mud, thanks. You making these videos to sell or what's the deal?

Bluesman, Thank Stan I just ask the question he's the one with the info lol

[SICFabrications]

waiting on simon for the vids...... he has all the footage on these..... as i run across the demand for various welds and what-not, i will post them as i can.... so far, i havent found a camera with or without a hood that can see the weld clearly as it is getting laid down...... still trying tho

that would end up with about a 500 page book if not more with the dos and dont )

Here is a wealth of free Knowledge WELDING Symbols And Definitions

Hi I was going through some photos from a cat site and found this image of a repair, does anybody know why it was done like this, I can understand the Y shapped protuding fillets on the cat but on the weldment metal itself I cannot see why it was done.Anybody?

It looks like they welded HRS to cast iron, if so the Y s are to prevent the casting from cracking. My 2¢ worth
