## How is welding current calculated?

To get the results in KJ/in or KJ/mm, divide the result by 1000.

- Example 1: If a welder takes 2 minutes to complete an 18 inches long weld.
- Answer:
- Travel Speed = Length of Weld/Time to weld = 18 inches/2 minutes = 9 in/min.
- Voltage = 24 volts.
- Current = 120 amps.
- Heat Input = (24 X 120 X 60)/ 9 = 19200 J/in.
- Table – 1.

**How are welding parameters calculated?**

The formula is as follows:

- Heat Input = (60 x Amps x Volts) / (1,000 x Travel Speed in in/min) = KJ/in.
- Travel Speed = Length of Weld / Time to weld = 25 inches / 2 minutes = 12.5 inches per minute.
- Heat Input = [(60 sec/min) x (325 amps) x (29 volts)] / [(1,000 joules/kilojoule) x (12.5 inches/minute)]

**How do you calculate welding cost?**

Calculate energy consumption (Kwh/product)

- Welding current, Amp. Ampere.
- Welding voltage, V. Voltage.
- Consumption / product during arc on. Kwh/product.
- Consumption / product during arc off. Kwh/product.
- Total consumption per product. Kwh/product.

### What is ASME IX welding?

asme section 9 is also called section IX. it is the qualification for welders for pressure pipe and vessels. it covers both brazing and welding and it is pretty much the industry standard for testing of pipe welders for power plants and such. Return to Welding Certification Forum.

**How many amps does it take to weld 1 inch steel?**

Broadly speaking, you need 1 amp of power for every . 001” of steel thickness. Stainless steel and welding out-of-position require 10 to 15% less heat input, while aluminum requires about 25% more.

**How is arc welding time calculated?**

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 .

#### How do you calculate welding materials?

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 much should I charge for a weld?**

The national average hourly rate for welding services ranges from $65–$125, often with a minimum service fee to cover overhead and transportation. Most welding shops charge an hourly rate for services, particularly if they’re doing straightforward jobs or pipeline work.

**What is ASME standard for welding?**

ASME section IX is a part of the ASME boiler pressure vessel code that contains the rules for qualifying welding procedures and welders. It is also used to qualify welders and procedures for welding to ASME B31.

## What is ASME welding code?

The ASME code requires that welders are certified to specific weld procedures used to fabricate the ASME code vessel. Welder certifications must be documented and maintained. A weld map must be generated that shows which welder performed each weld on an ASME code vessel.

**How do you calculate weld size?**

Calculate the weld size, s, at each node on the intersecting edge of the terminated part: SS or DS groove welds: s = t. SS or DS 45 ° fillet welds: s = sqrt(2) × t.

**How do you calculate weld volume?**

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 much do rig welders make?

While ZipRecruiter is seeing annual salaries as high as $137,500 and as low as $11,000, the majority of RIG Welder salaries currently range between $46,000 (25th percentile) to $101,000 (75th percentile) with top earners (90th percentile) making $134,500 annually across the United States.
