**Calculate**the

**weld**area (cross section of the

**weld**) including root and cap reinforcement in square millimetres. 2) Multiply

**weld**area by pipe circumference (

**weld**length) to give a

**weld**volume in cubic millimetres. 3) Divide this answer by 1,000,000,000 to give

**weld**volume in cubic metres.

In this manner, how is welding consumption calculated?

1 **Calculating** Filler Metal **Consumption** The number of pounds of **welding** electrodes or **welding** wire necessary to complete a given **weld** joint may be **calculated** by the **formula**: P = WL E Where: P = Pounds of electrode or wire required W = Weight per foot of **weld** metal L = Length of **weld** (feet) E = Deposition efficiency

how many amps does it take to weld a 1/4 inch steel? For example, to MIG-**weld** 18-gauge **steel** in a single pass takes roughly 70 **amps**. **Welding 1/4**-**inch steel** in a single pass requires roughly 180 **amps**.

Accordingly, how do you calculate welding time?

EXAMPLE 1) **Welding Time** = Wt/Ft of **Weld** x Ft of **Weld** Deposition Rate x Operating Factor Substituting the values in Example 1: . 814 x 1,280 5.36 x . 30 = 1,042 1.608 = 648 Hrs.

How do you calculate welding thickness?

The size of fillet **weld** height approximately specifies the = 0.7 formula, where z is the fillet **weld** width. Minimum fillet **weld** height is selected according to the **thickness** of the **thicker welded** part and according to the material.
