## Fillet Size Calculation

Hi...

I am designing for 20mm with 25mm T-joint. what will be the throat size? and how much load that particular weld area can carry? bcoz i will lift the job with over hoist. wt of the job will be 2 ton...

Can any one help me?

How long is this joint? On plate that thick it wont need a lot for that weight, usually 3/8 or 1/2 but there are other factors.

First of all many thanks

I am using rectanguler block of 80 X 80 X 20mm thk.. Weld all around. Sir..is there any standard formula for calculating leg length and throat thickness.

1. Z = a x sqrt 2
2. .707 x t = Leg length

These formula i know but i refer so many drgs but all the time i am getting different sizes of weld.

This website may help. Look down the left hand column for joint design, etc.

Good Luck,

5. We really need a photo or a drawing.

Welds in shear ??

In general If a rod is E7018 it means 70,000 lbs tensile strength PER INCH.
You need a set of welding inspection guages for measuring the throat of a weld.
The width of a weld is about two rods wide with the flux coating on.

There are other factors.
Never stand under ANY load being lifted.
