Too long an arc length allows the arc to wander creating a poorly shaped weld. The slag is usually too thin and can allow Oxygen in the air to attack the molten puddle which causes Porosity in the weld. Too short an arc length buries the slag and creates less heat which traps the slag and impurities. Keep in mind that electrode coatings help determine the correct arc length.

What is the arc length of the minor arc of 95 and 18.84?
find the arc length of minor arc 95 c= 18.84
What is Arc length in welding?
Arc length is the distance from the tip of the electrode to the workpiece.
The circumference of Z is 72 in What is the length of the minor arc?
It is: 72-lenghth of major arc = length of minor arc
If the central angle of a circle is twenty degrees and the radius is fifty centimeters what is the arc length?
20/360=arc length/2pi*50; 1/12=arc length/100pi. 100pi/12=arc length. arc length=25pi/3 centimeters, which is approximately 26.17993878 centimeters.
How would you avoid the occurrence of porosity or slag on weld?
Correct current,travel speed, electrode angle, arc length
Why is it important to strike the arc only on the weld joint?
why is it important only to strike the arc in the weld joint
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
Can weld without flux is possible?
You can arc weld & then the flux will be in the rod.
How does arc length affect voltage?
The longer you strech the arc, the smaller the voltage. Current rises though.
How does arc blow affect welding?
Arc blow is a magnetic field formed in the weld area. It will pull the arc back and forth keeping it from being concentrated directly ahead of the electrode. Metal in some areas will not be melted and slag will flow into these voids trapping it. The arc can expel molten metal from the joint creating spatter. Arc blow can be very severe. You can avoid this by connecting the work lead to the end of the weld joint. Then work away from the work lead.
The length of arc AB is 28.61 What is the length of arc ACB?
The length of arc ACB is 57.2.
Arc length equals the measure of the arc?
The arc length is the radius times the arc degree in radians
Is flux cored arc a high precision weld?
yes
Who to arc length Radius of the circle 4756 and angle 45deg find arc length?
(arc length)/circumference=(measure of central angle)/(360 degrees) (arc length)/(2pi*4756)=(45 degrees)/(360 degrees) (arc length)/(9512pi)=45/360 (arc length)=(9512pi)/8 (arc length)=1189pi, which is approximately 3735.3536651
What is arc voltage or arc length?
It just means length.
How does length of gas nozzle effect mig welding?
The legth of the gas nozzle can affect the MIG welding process because it modifies the "electrode extension" or so called stickout. The longer the nozzle the longer electrode extension needed to keep the arc away from it thus the value od the welding current and arc voltage changes. These changes will have a great effect on the weld.
