What is the proper arc gap in welding?

Arc spacing: Adjust travel speed so that the welding arc stays within the leading one third of the weld pool. For wire (flux-core or MIG) welding, keep a work distance of ⅜ to ½ inch. With stick welding, look to keep that distance ⅛ inch between the rod tip and work piece.

What is the correct arc length for SMAW?

Arc length for 1/16 and 3/32 in. diameter electrodes should be about 1/16 in. (1.6 mm); arc length for 1/8 and 5/32 in. elec- trodes should be about 1/8 in.

What is arc characteristics in welding?

It has a slightly downward or negative slope because of sufficient internal electrical resistance and inductance in the welding circuit to cause a minor droop in the output volt ampere characteristics. With constant voltage power supply the arc voltage is established by setting the output voltage on the source.

What is the 5 weaving motion in 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.

What is ideal length of arc?

Length of arc: The correct arc length varies with each electrode and application. As a good starting point, arc length should not exceed the diameter of the metal portion (core) of the electrode. For example, an 1/8-inch 6010 electrode is held about 1/8 inch off the base material.

What is normal arc length?

In general, the arc length is 0.10 inch and this measurement is taken as a base. One half of the weld penetration is combined with the base measurement and this results in the arc length for a certain amperage.

What is the ideal arc length?

How many types of arc welding are there?

There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW). We dive deeper into each type of welding here.

What flux is used for submerged arc welding?

The molten weld and the arc zone are protected from atmospheric contamination by being “submerged” under a blanket of granular fusible flux consisting of lime, silica, manganese oxide, calcium fluoride, and other compounds.
