How do you measure groove weld?

Determine the weld size. This includes the depth of groove and the additional penetration into the root. The size of weld will be shown to the left of the groove symbol in parenthesis. If there is no number in parenthesis then the size of the weld should not be less than the groove depth.

How is weld width calculated?

the width of the weld cap, w, is given by w = 2(tan b x (t-r)) + g +2r. the area of the excess weld metal is given by the formula (w x h)/2. the area ‘A’ is (t-r) x (2r +g). the area ‘B’ is g x r.

How do you calculate welding consumables?

1) 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.

What is the difference between butt weld and groove weld?

In a groove or butt weld, the components being connected are located on the same plane. Groove welds and butt welds refer to the same weld type, where groove weld is the American National Standards Institute (ANSI) term, and butt weld is the International Organization for Standardization (ISO) term.

What is the minimum weld size?

Minimum Fillet Weld Size per AWS D1. 1 Table

Base metal thickness (T) a Minimum size of fillet weld b

T < 1/4 T < 6 1/8 c
1/4 < T < 1/2 6 < T < 12 3/16
1/2 < T < 3/4 12 < T < 20 1/4

How do you calculate welding weight?

CALCULATING THE WEIGHT PER FOOT OF A FILLET WELD In the fillet weld shown below, the area of the cross-section (the triangle) is equal to one half the base times the height, the volume of the weld is equal to the area times the length, and the weight of the weld then, is the volume times the weight of the material ( …

How are welding rates calculated?

Calculate energy consumption (Kwh/product)

  1. Welding current, Amp. Ampere.
  2. Welding voltage, V. Voltage.
  3. Consumption / product during arc on. Kwh/product.
  4. Consumption / product during arc off. Kwh/product.
  5. Total consumption per product. Kwh/product.

How much is welding per hour?

The average welder can complete about 140 inches of weld per hour. The number of welds per hour is the same as the diameter of the pipe. You can get an hourly rate of pipeline joints.

What do you need to know about groove welding?

Often associated with a groove weld is going to be the weld size. This weld size is the depth of penetration you will be getting when applying the weld. When a weld is applied we should be melting into the root of the part so our weld should be larger in dimension than the preparation of the joint.

What is the radius of a groove weld?

Its value depends on the welding process used and application; for a full penetration weld on carbon steel plates, it has a value between 1-4mm. The radius of the curved portion of the fusion face in a component prepared for a single J, single U, double J or double U weld.

How to calculate volume of a V butt weld?

There are three factors that determine the volume of the weld in a single V butt weld. These are the angle of the bevel, b, the excess weld metal and the root gap, g, as illustrated in Fig 3. To calculate the area of this weld we need to be able to add together the areas of the four components illustrated in Fig.3.

What are the dimensions of a groove welding symbol?

These dimensions must be shown in a detail or section view that is noted in the tail of the welding symbol. The preparation of the groove may be called out for how deep you are to prepare the part. This is called the depth of groove. V- Grooves, j- grooves, and u- grooves are the most commonly sized welds for depth.
