What is the distance from the tip of the bare end of the electrode to the base metal?

What is the distance from the tip of the bare end of the electrode to the base metal?

Arc length
Arc length is the distance from the tip of the bare end of the electrode to the base metal. b. Arc length is equal to the diameter of the bare end of the electrode. 4.

What is between the end of the electrode and the base metal?

Arc
Arc — is what is between the end of the electrode and the base metal. The resistance causes heat. Automatic Welding — is a weld made by equipment such as robots. Backup Strip — is a strip or section of steel butted up to an open gap between two pieces of steel.

What term refers to the distance between the tip of the bare end of the electrode and the base metal in shielded metal arc welding?

Arc Length. The distance from the tip of the bare end of the electrode to the base metal. arc welding. A process that uses electricity to heat and melt metal. duty cycle.

Is the distance from the tip of the electrode core wire to the weld puddle?

Arc length is the distance from the tip of the electrode core wire to the weld puddle.

What does the 70 in 7018 mean?

For example, the number 70 in a E7018 electrode indicates that the electrode will produce a weld bead with a minimum tensile strength of 70,000 psi. The third digit represents the welding position(s) for which the electrode can be used.

What is a Weldor?

One who welds, or unites pieces of iron, etc., by welding. One who welds, or wields. A manager; an actual occupant. An item of equipment for welding with: an electric welder.

What is the final pass of a weld called?

cover pass. the final weld pass of a multiple-pass weld that forms the weld face.

Why is it needed to keep the distance between an electrode and base metal?

The arc between the welding electrode and the base metal is struck (initiated) by the welder. The welder must keep the electrode positioned the proper distance from the workpiece (arc length) to maintain the arc.

What is the term for the length of wire from the end of the electrode to the contact tip?

Electrode extension: As defined by the American Welding Society (AWS), this refers to the length from the end of the contact tip to where the wire melts off.

Is the distance from the contact tube to the end of the electrode wire?

electrode extension
2.8. The stick-out or electrode extension is the distance between the tip of the contact tube and the end of the electrode.

What is the distance between the end of the electrode and weld pool?

The distance from the tip of the welding electrode to the adjacent surface of the weld pool.

What does 6010 mean on a welding rod?

The “60” in 6010 means 60,000 pounds’ tensile strength (the ability to resist being pulled apart) per square inch. The “1” means it can be run in any position—flat, horizontal, vertical, or overhead.

How are arc length and electrode extension measured?

Once the arc is struck, arc length is measured by voltage, and electrode extension can be measured by resistance in the circuit or with sight. When people use the term contact-tip-to-work distance, they often mean the sum of arc length and electrode extension.

How big does a grounded metal system have to be to be bonded?

11.4 Grounded metal bodies that are within 6 feet (1.8 m) of the main conductor shall be bonded to the system.

Why is electrode extension so important in welding?

Maintaining consistent electrode extension during welding is critical because varying the extension can change your amperage, which can put you out of range of your welding specifications. When that happens, you may be depositing a weld that’s less than sound.

What happens when electrode extension is too short?

Too short of an electrode extension increases the amperage and brings you closer to the weld pool, which can cause premature damage to the contact tip and create burn-through from too much heat. Too much extension lowers the amperage and can result in poor penetration that requires rework.
