Fillet Welds

We're going to  talk about one of the most basic weld  probably the most common weld you're  ever gonna perform alright I'll give you  a few seconds to guess what it is  everybody got it all right  it's the filling if you haven't guessed  that the Philip load is probably the  most common weld out there and I've got  some pieces of metal here and we're gonna do and fill it welds with them .

We're gonna be doing SMAW shielded metal arc welding stick welding because that's  probably the easiest way to go about learning to weld and that's what we're  here for is to help you learn to be a  welder alright if you don't know the  proper terminology for the parts of the  weld  look right here pause your video if you  want so that you have an idea okay so you know what we're talking about all  right the one thing.

We're going to be talking about is when we have our fill  at weld which will be the weld that goes  right in here we'll be talking about the  face of the weld and the face size of  the weld  now for instance this is 3/8 inch thick 10:18 mild steel this is quarter inch  thick and  eighteen mild steel now I had used this  previously for some TIG practice so I  had to clean it up.

That's why it's shiny  you still have the mill scale on  basically the same steel though all  right so what we're going to be talking about is the face of the weld and face  size or fill it weld size and here's the here's the key point that I want to get  across to you the Philip weld size need  be no larger than the thickness of the  thinnest member of the weld let me bring you in closer and we'll talk about this better all right now again when we're  talking about a Filat weld we can be  talking about an inside corner joint or a tee joint .

We're not talking about the  actual joint make up we're simply talking about the type of weld which is the filler weld and that is a weld that  fills up this area between the  horizontal member and the vertical  member I'm calling horizontal and  vertical in this instance they don't  have to be the joint could be positioned  like this you would be welding here it  would still be a football but anyway so  here we have 3/8 inch steel to 3/8 inch  steel and this weld that we're gonna lay in here .

To hold these two together does  not need to be any thicker than  three-eighths of an inch if it is any thicker it's certainly not going to hurt  anything although it may cause some  distortion because of the excess heat  it's not going to help anything now here  we are we welding a piece of quarter  inch steel to a piece of 3/8 inch steel  and again we don't want that fill it well to be any thicker than this  anything that's thicker than your thinnest member is wasted metal wasted  material wasted money wasted time .

Alright so we'll be doing  3/8 to 3/8 and a 3/8 to quarter-inch so you'll be able to see two different thickness sizes in the metal here so let  me get set up and we'll be back and  ready to well all right we've got our  test piece tacked up here I've tacked it  on the edges held everything in place  with the magnet to make sure it's all  nice and square.
