Weld Seam Removal: Grinding Disc vs. Fibre Disc vs. SMT Flap Disc | KLINGSPOR Abrasives USA

[Music]

today we're going to talk about one of

our many questions we get which of these

products are a grinding disc fiber disc

or a flat disc do we use to take down

different varieties of metal today we're

going to talk about it with a weld

so the first one we're going to talk

about is our grinding disc this is made

up of grit resin teflon inner layer

and your pore filler so what this does

you put all that together you're going

to have a very hard disk

so this right here you're able to remove

faster and that's something we'll be

able to show you more in depth further

into the video the next one is and so

here we have a klingspor fiber disc and

what it is it's just a vulcanized fiber

backing

which has abrasive grain bonded to it

usually in this case it's either going

to be aluminum zirconia or it's going to

be a ceramic aluminum oxide just because

you get a little more out of those

they're more aggressive and they last

longer so one thing i do want to hit on

is that these do have to be around with

a backing pad

so it's sole purpose there is just to

add support

because even though these are pretty

stiff durable backing if you run them

without the pads they will rip and

possibly break apart causing damage so

be sure and run these with the clean

sport backing pads as well

on my right here we have a cling spore

flap disc and essentially what it is

it's just a polyester abrasive cut into

little squares

and they're going to be glued to a

backing usually that's going to be a

fiberglass backing it's more lightweight

less heat build up things like that so

this has a built-in backing so there's

no really backing pad needed and this is

used as the same application as a fiber

disc and we'll go through the advantages

of each

depending on the application they kind

of each have their sole purpose and

sometimes it comes down to just a matter

of preference

so what we're going to do at this point

is we're going to take these welds down

with each of these and then at the end

of the video we're going to discuss the

advantages and actually you can see the

advantages of them so we are going to

time how long it takes to remove because

that is going to be a big factor as well

so just stay tuned

so as you can see in the photo the

grinding disc went about 15 faster than

the other ones but at the same time the

whole point for this is just to remove

that weld so you can see it's got gouge

marks and those inside that pitcher but

really for a grinding disc the whole

point of this it's a workhorse it is

going to remove really fast and it's

probably not going to look as pretty as

it when it's done

but we're getting that weld down and

we're good to go

the next one you can see the fiber disc

here it's a little bit more grainy in

terms of finish so you can see those

scratches left so it's not going to be

quite as aggressive as the grotting disc

danny used

but it's going to be close behind it and

it's kind of going to be that

intermediate finish

and one thing i do want to hit on you

can see the grinding area here is much

wider than that weld was so if you're

looking for a good aggression remember

it is going to touch the work piece

under it so it might be a little bit

wider than the weld

it is going to leave a wider scratch

and speaking of that it kind of brings

me to the flat disc here you can see it

leaves the best finish of the three

all while maintaining pretty good

aggression not as much as the other two

but you can see it's going to leave the

best finish while maintaining a good

aggression advantages to the flat disc

because you can kind of determine how

wide you want the grinding area to be

this one was an angled flap disc so you

can see it's much more narrow so if

you're looking for something just to

remove the weld and not touch the work

piece an angled flat disc would be a

really good option so

and as you can see these pictures again

this one leaves the best finish of the

three

so thank you all so much for joining us

for this metal video and we'll see you

next time
