How do you calculate electrode consumption?

Q. How do you calculate electrode consumption?

The electrode consumption per metre of welded joint is obtained by dividing the number of kg of weld metal by N, where N is the kg of weld metal per kg of electrode.

Q. What size electrode do I need?

Generally the size of the electrode that should be used depends on the thickness of the part to be welded. For thin metals the electrode is only slightly larger than the metal to be welded. For example if a plate is of 2.0 mm thick the electrode of 2.5 mm should be used.

Q. What are the most common electrode lengths?

The most commonly used sizes, however, are the . 040″, 1/16″, 3/32″, and 1/8″ diameters. 2.3. 5.1 The shape of the tip of the electrode is an important factor in gas tungsten arc welding.

Q. What does the 1 in E7018 mean?

The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen and usually DC current.E

Q. How is welding length calculated?

The length of the weld size La is calculated according to Ref. [32] part 4.5. 3.3.. The default throat thickness a is equal to plate thickness/2….Calculation of weld length.

a	the throat thickness
Fw;Rd	the weld design resistance per unit length
fvw.d	the design shear strength of the weld
fu	the ultimate tensile strength of the weld

Q. How is 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 .

Q. How do you read electrode numbers?

The prefix “E” designates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of 5-digit number indicate minimum tensile strength. For example, E6010 is a 60,000 psi tensile strength electrode while E10018 designates a 100,000 psi tensile strength electrode.

Q. How long is a duty cycle?

10-minute
Duty cycle is the amount of time it may be operated at a given output without exceeding the temperature limits of its components, and it is measured using a 10-minute cycle.

Q. What welds better AC or DC?

DC stick welding offers advantages over AC when welding steel, including smoother and more stable arcs, easier starts, fewer arc outages, less spatter and easier vertical up and overhead welding. DC positive polarity provides a high level of penetration into the steel.
