CWB Video Part 4 of Four. Preparation of Test Coupons, Bending and Inspection to CSA 47.1.mov
CWB Bend Test for weld coupons. A brief explanation of the correct placement method for coupons when doing a bend test, the analysis of results and what the ...
Hi. Within a few months i will be working on Coupon testing of Composite
materials. Presently I have been asked to do literature study on the topic.
So starting from the most basic question can you please tell me what does a
Coupon mean? and what is a Coupon for Composite material. It will be very
helpful for me to know these stuffs.
Here's 3000 in coupon savings. 1000 grocery stores 1000 restaurants 1000
general merchandise I also discovered lots of other great ways to save
money with discount coupons. This one is the real deal for sure.
groceryandrestaurantsavings (dot) com
the coupons should be ground flush to the same size as the parent metal...
for example if you have 3/8" parent metal the grinding on the weld zone
should meet the same criteria

Glasses, yes. Gloves, NO! It's far too easy for a glove to catch in
rotating parts, and that will cause much more damage than just getting a
little nick if you get too close, and the sparks don't have enough energy
to break OR burn skin. With bare hands, you can really feel what you are
doing and you can control the metal better. If it's getting too hot to
touch, you're grinding too much too fast. NO GLOVES around rotating parts!
Wicked!! thanks man this helps out a lot! we just started open root. 6011
for the root pass and 7018 for the hot pass and fill. we are soon moving on
to tig tho and i'm so excited for it! you make it look so easy. I was to
specialize in tig so i hope i can pull it off. Anyways thanks for making
this vid. I'm going to try and get my teacher to show it to the class.
yer buddy was a hard test though. i had a guy from the lloyds register
timing my root and hot pass. then he timed me on my cap! something to do
with the heat input lol. Then when we got to Kuwait we had to do 3 more
f**king tests. still passed them though :P
the best welding school in houston texas is San Jacinto College. hands
down. now there is other private schools taught by retired guys who are
pretty damn good, but i only encountered one of those schools and there
seems to be 3 or 4 dozen of them.
I suck at welding aluminum when its butted up against eachother with no
gap. Here you are with a monster gap throwing it down like a pro hahha.
Much to learn!!!! :)
It would be super cool if you can show a small side screen with how your
applying your foot pedal in this welding procedure! Keep up the awesome
work...
CWB Video Part 2 of Four. Preparation for Welding to CSA W47.1.mov
CWB guide for preparation for Shielded Metal Arc Welding, and Flux Core Arc Welding, an explanation of the stop and start welding methods required when ...
After reviewing many of your other posts I have come to the conclusion that
you are just a retard. You absolutely can check your liner if you're not a
fucking moron...which you clearly are. CWB and ABSA are governed by the
same departments they are just different outfits. Some people only require
CWB for their job so ABSA is irrelevant. You also talk a lot of shit on
peoples welding videos for someone who has none of their own. Seems to me
like you're just a jealous child. Grow up, cunt.
And for 2,... NEVER get in a habbit of dragging or PULLING your weld!!!!
the position of your tip/cone on a mig makes changes to the way it not only
welds but the shielding (GAS)!!! the whole point of getting into welding is
finding a decent job makeing GOOD money!!! and the only way to do that is 2
ways.. work fast,.. and know how to do welding properly!!! if you go into
the places that are gonna give you the $16 an hour and do things like pull
your weld.. NOT know how to set your mach.. NO JOB
I am a welding instructor and a welding inspector in Toronto. I am a CWB
qualified welder in GMAW in the horizontal position done in spray transfer.
I'm also all-position qualified (flat/horizontal/vertical-up& overhead) in
GTAW, SMAW & FCAW! Not sure where you are from but you don't know what
you're talking about in regards to testing in Canada to the CSA Standard
W47.1 & W59. There is no pre-qualified joint testing in GMAW for vertical
or overhead. I never mentioned anything about vertical s
the biggest problem i see... you dont even somewhat look like you are in a
comfortable posistion for 1, and a way to remedy this is put a clamp on
your work, hell ill put anothe drop of say angle against the wrok so it
doesnt burn my hand! free handing is NEVER going to be as consistant as
welding with you in a proper strong body position that is comfortable to
you! prop that hand and be relaxed! you will ALWAYS see a much more
consistant weld! remember... Technic is only developed over time!
That stop and start wasn't pretty, but luckily that's where you usually cut
the plate for the bend. I jacked up my cutting last night and had to use
the edge of my plate where the welds stopped at the end. Luckily, I always
cut them a bit wider than the book says to give me room for cutting error,
(I hate using torches). I didn't do much of anything different than this
video here, and I got a 97% on my test. All in all, I'd say it wasn't a bad
video. Just work on your restarts. Good job.
For one the weld looks like sh*% because you free handed it and you're not
good enough for it. Two you have a back plate on it. Anyone who can halfway
weld can do this weld with a back plate on it. Get you some 3/4 inch plate
about 10 inches long and 8 inches tall, cut it in half long ways. Put you a
bevel in your top piece. Fit it up with a 1/8 inch gap between the plates
(with the bevel in the gap on top). Put you a MIG route (with no back
plate) then fill and cap it with FLUX.
i dont like the way you move the torch around you dont need to do circle's
in your passes that is not right at all when you form a puddle the molton
puddle of weld is already round why would you abuse your wrist like that i
will never understand it.. but looks like a good clean weld.. with that
thickness you would get better penitration with straight co 2... to me the
second and third one one you were going to fast ... man good thing you are
not busy took along time
Pushing the puddle and pulling are all preference and situation specific.
Just as vertical down and vertical up are(except with FCAW and SMAW.) You
don't get as much penetration when pushing with MIG, therefore, he actually
made the proper decision to pull the puddle. It's a test plate,
penetration=PASS. Also, quote me if I'm wrong, but I saw no porosity* in
his welds. His travel speed was a bit fast, but at least know your facts
before unjustly critiquing someone.
the BEST tip i have for ANYONE that wants to learn how to weld and do
fabrication..... start out burning rods!!! once you can burn 7018s
uphill... then you put a mig in their hand!!!! and learn EVERYTHING related
to the trade!!! just cause you can weld doesnt mean shit if you cant take a
drawing and make all your parts, fit, and weld the work!!! if you cant
fabricate your parts then you are useless in a shop that pays! Good Luck!
to you guys!

MIG welding stands for Metal Inert Gas welding (inert). An inert gas (rare
gas) is e.g. Argon or Argon + Helium. Its task is to protect the welding
deposit, MAG welding stands for Metal Active Gas welding (chemically
active). An active gas is e.g. a gas of the protective gas category M21,
also known as mixed gas 18 or MIX 18 (trade names). These protective gases
react during welding :)
Not bad for a school weld. But in the real world an inspector would shit if
he saw you running hard wire in short circuit. The only way you should ever
run hard wire in a "structural" manner is in spray so ~27+ volts (depending
on gas). This sounds like maybe 23 tops. If you are going to cert
structural go FCAW 3G super easy. And you should NEVER quench between
passes!
unless you were trying to tell him that most ppl confuse MAG with MIG and
that in reality MIG is active gas because most places using it are using
Co2 so if thats what your saying then your correct. but they dont use Co2
for non ferrous metals.You would think they should since its cheaper and
may not react with them but I may be wrong on that.
@redneckman454 do u know how to braze weld cuz i do i dont wanna be mean or
anything cuz i see some post but i do welding in tech and im a sophmore aka
10th grader i know how to use oxy acetylen and now stck b0ut next year i
will learn to weld pipe with stick and then after tht i will learn tig good
luck on the certification dude
You know, there is some world outside of the USA: countries where arc
welding was actually invented (Russia, 1881–1882, Nikolai Bernardos) In
Europe and in Russia they don't worry about AWS opinion; MIG is the legit
name there, but they also aware that GMAW is an alternative name for the
process at the wild West.
@redneckman454 do u know how to braze weld im just curious cuz i do i dont
wanna be mean cuz im just a sopmore aka 10th grade in side votech taking up
welding class but right now im stick welding next year i might do pipe with
stick and tig and good luck for the passing u will do well
pushing just makes sure the gas cleans the weld properly its hardly gonna
cool it quicker ya might aswell blow on it ha ha...if ya just weave back
and forward slightly ya go back into the puddle making better penetration
:) plus if ya not penetrating properly turn ya machine up...;)
why are you doing circular motions like that?really extreme,and its a
bullshit technique for guys that arent steady enough to lay one down,just
saying,you can tell your in school bud,once you school guys get a
grip,youll understand what welding is in the real world,keep at it
ha ha good set up before welding.......half circles work better and are
flatter than whole circles had lack of fusion in starts and to make your
plate even go left to right then right to left cause the angle change
effects buildup......not a good video to learn on
You should learn what to do when welding a 2g horizontal weld test before
making a video about it. The first pass should have a stop/start about the
last 2 or so inchs before the end of the coupon but this video doesn't. So,
it's a fail right there!
@gom9r you are right anyone can do it, but can they do it well, i think
not, even though mig welding is easy in my opinion there are people like
you that think they know something when they dont know shit. I can tell
because of your comment.
actually guy, i jus took, and passed, first try, a bend test. and i did it
short circuit, so i dont know if you jus cant do it, but i had no problems
whatsoever witrh it. actually going to take my unlimited today....
@welderbones you dont use spray transfer for any other position then
flat... i dare you to make a vertical test plate using spray transfer...
this guy was right to use short circuit transfer for his horizontal test
dont use a bend a circle just usd a stinger it works better and never put
it in water if your going to bend test it it gives you a better chance of a
failed weld but otherwise it was a ok video. keep it up
why do you have a backing piece in the root ive only used backing plate for
a horizontal spray transfer test not short circuit just use a 1/8th inch
and go then no need to cut that backing plate off
i dont understand stupid comments. So many stupid people think they can do
better or asking why dont you try it in another position. how about because
the video is called from 2g position. retard
I agree, inspector will want to see two root passes for 2g a stop and start
on the bevel side, usually shouldn't even weave unless your doing your
cover passes unless you cant run straight beads
MIG aka Metal Inert Gas, MAG aka Metal Active Gas. Of course in Europe
norm, i dont know where do you from. Maybe Australia and USA got other
norms and names, so thats why i get confused.
very awsome man im on elctrodes over head and its a pain in the ass im
using 7018 1/4 rods at 85 volts and using a whipping motion (i cant do it
in circles) i just have to keep practicing
Ok why dont you just lay it on a table its just the same it EASY . Im a
certified welder and i run that weld 50 times a week. Try it in a 4g
position with flux core wire or even in a 3g .
Welding Position 1G - Flat Groove Weld
Groove welds are made in the groove between the work pieces. Groove welds can take the shape of all of the joint types. This video illustrates welding a flat ...
+Andrew Taylor, the welder is welding in a zigzag pattern. Please keep in mind these videos are intended to display a typical weld in the position indicated. Ultimately, you will need to develop and test your own procedures to ensure that you are depositing a sound weld. Please let us know if you have any further questions.
Welding GMAW (MIG) Certification bend test
This bend test is on a 3/8" v-groove w/ 22.5 degree bevels. It was welded in the vertical up position using the GMAW . (Gas Metal Arc Welder)
This bender takes forever, the one we used at Hobart you could just set the
plate down on a table with a hole in it and it would press it through. Must
faster.
