What is weaving in arc welding?
Weaving motion (uniform side-to-side motion) is applied to the electrode which gives better fusion of the weld metal. This weaving motion or process should be repeated on welding beads from left to right, right to left, and top to bottom, and bottom to top—to build up an uniform appearance of the weld metal.
Should you weave when MIG welding?
The general guidelines for MIG welding are whip when welding thin metal or making the first pass in a joint, circles for a both thicker materials and wider welds. Weave for vertical up and down.
Is Tig stronger than MIG?
Bottom Line. TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.
Is it better to weld up or down?
A vertical up weld will penetrate better while a vertical down weld may look more aesthetically pleasing. Both welds take practice to learn but can be very helpful when used in certain situations. … You can weld from the bottom, working your way towards the top of the joint.
What is the work angle?
The work angle is the angle between a line perpendicular to the nonbutting surface and the plane containing the weld axis and the electrode axis.
What is peening in welding?
Peening is a cold working process in which the surface of the component is deliberately deformed, in the basic method, by hammering. During peening, the surface layer attempts to expand laterally but is prevented from doing so by the elastic nature of the sub-surface, bulk material. … hammer.
Do you weave stick welding?
For welding vertical up, use a push or forehand technique and tilt the top of the electrode 0 to 15 degrees away from the direction of travel. … Note that on material 1/4 inch and thinner, weaving the electrode is typically not needed because the bead will be wider than necessary.
What is string or weave bead in welding?
FILLER PASS WELDING Weave beads, produced by weaving the torch across the joint, can be used on carbon and low-alloy steel in the rolled or horizontal-fixed position. Stringer beads, laid parallel to the joint, are used for welding stainless steel pipe since there is less tendency toward carbide precipitation.
What can occur if the current setting is too low?
Setting the amps too low will result in a tall, narrow bead lacking in penetration. The weld will be difficult to start and the arc prone to straying towards one side of a joint in preference to the other.
