Dave tack welds during fit up do require preheat unless they are to be ground out during weld out and incorporated into the weldment. And I've preheated plenty joints with weldments less than 1"T, as per the WPS. IM SURE THE INDUCTION BLANKETS or RoseBud went to work prior to weld out
Anything 3/4 to 1-1/2 inch thick needs to be preheated to a minimum 150 degrees. Anything 1-1/2 to2-1/2 225 degrees . Anything above 2-1/2 needs to be at 300 . This is per AWS d1.1 structural code . This is to prevent hydrogen cracking and has to be done it would not pass UT . This is very common knowledge for anything structural . With that being said looks like he was just tac welding as he never showed the full welding process I would imagine he preheated it unless he’s in Mexico or a 3rd world country
What number filter do tou use for welding fumes?thanks for sharing very nive video...

Chaque fois chaque fois je regarde votre je veux voir vos vidéos ça j'aimerais que si au moins j'aurai ok mais
I know the work of welding can you arrange me a job. I am currently in Croatia
Preheat to the very least 350° usually the tack will crack or weld if you dont

선생님 이렇게 큰 h빔은 처음 봤어요. 어디서 살수있나요 ?
Для чего она тебе? Ты будешь строить Эйфелеву башню у себя во дворе? 😅
Bonjour
No welder does a tack without looking at it,he is a fabricator
What happens when the plate and beam doesn't line up?
Thats why God invented hammers. Big hammers!
Hammers, then yell at the steel fabricators for not making a 90° cut

Hello dear sir I am fitter I have 27 years experience in my technical field give me job
Safety squints = Engaged
Y la mascarilla. ¿ cuando ?😮😮😮
Beritahu saya jika anda mempunyai kerja di sini
Our factory specializes in manufacturing welding materials submerged arc welding agent for 30 years, win-win cooperation.
As Ironworker I've seen alot of crap fast welds by guy's in to much of a hurry and no prep just like this guy with no PPE !
Your damm rht M O 38 years cert.welder 7018 and 232 .072 seismic wire and 35 years structural Fabricator always pre heat at least 350° for 1" steel
That’s right, no spec, no Code of construction, so no WPS. Welder likes the “looks” of his weld but cold lap til hell freezes over! Rejected!

thats a big lump of steel.
You have to preheat no experience
Hii
@@ashadulislam7293 Yes hi sir
Hello
Yes hello.
Can never understand why when you could stand it up it people weld in position would be faster and neater wealded down hand not uphill
Depends on what process, doing a piece like that would suck with SMAW, but some FCAW-S 1/16” and up would make quick work of that in the field.
Tan feo eso de tener en la mano la mascarilla. Yo digo que tiene que ir . Donde corresponde en la cabesa. Vaje y suba. 😮😮😮😮
각장은 개 줬나 버티컬로 올려도 지킬건 지켜야지. 이런건 올리지 마셈 울나라 90년대 스타일
please clean a metal before fitting and welding!
Any steel over an inch thick is supposed to be preheated your weld is no good
what for?
Dave tack welds during fit up do require preheat unless they are to be ground out during weld out and incorporated into the weldment. And I've preheated plenty joints with weldments less than 1"T, as per the WPS. IM SURE THE INDUCTION BLANKETS or RoseBud went to work prior to weld out
Anything 3/4 to 1-1/2 inch thick needs to be preheated to a minimum 150 degrees.
Anything 1-1/2 to2-1/2 225 degrees .
Anything above 2-1/2 needs to be at 300 .

Actually with how there holding there hoods it proably isn’t in America .
And yes it’s not cast iron haha they stopped using iron structurally in the 1900s . Local 433 ironworker here 👋
