You are watching: Why is it important to strike the arc only in the weld joint


Shielded steel Arc Welding (SMAW) operation requires a setup and then weld.

In general, the operator factor, or the percentage of the operator’s time invested laying weld, is approximately 25%. The remainder is invested in preparation and in remove slag.

The yes, really welding an approach utilized depends on the electrode, the ingredient of the workpiece, and also the place of the joint gift welded.

The an option of electrode and welding position also determines the welding speed.

Flat welds call for the the very least operator skill and can it is in done through electrodes the melt quickly however solidify slowly. This permits higher welding speeds.

Sloped, vertical or upside-down welding requires much more operator skill and often necessitates the use of an electrode the solidifies easily to protect against the molten steel from flowing the end of the weld pool.

However, this generally means that the electrode melts much less quickly, for this reason increasing the time compelled to put the weld.

SMAW operation Set-up

Before beginning make sure that you space using a great helmet because that SMAW welding and also protective clothing.

Clean the workpieceClamp the work close to the weldInsert the electrode into the insulated holder holder. Collection amperage at level recommended by the electrode manufacturer.Determine the best arc length. Together a guideline the arc for a 1/16″ to 3/32″ diameter electrode is 1/16″ (1.6mm). The arc lengh for a 1/8″ and also 5/32″ electrode is 1/8″ (3mm).Stick Welding Examples

Test Welds utilizing a Hammer In The Direction shown Above. Weakness deserve to be because of Porosity (holes in the weld), Incorrect warm or quick Travel Speed.

Use a hammer come strike the share on the product welded to the base. The weld have to bend slightly and not break.

Breakage can be as result of too countless holes (porous) in the weld, or if the weld has slag.

Also keep in mind if any of the beveled area is visible.

If that is, this can indicate the the filler material was not fully melted because of traveling too quick with the electrode or by no using sufficient heat.

Slag Removal

Once hardened, it should be chipped far to reveal the perfect weld.

As welding progresses and also the electrode melts, the welder have to periodically stop welding to eliminate the continuing to be electrode stub and insert a new electrode right into the electrode holder.

This activity, combined with chipping away the slag, reduce the amount of time that the welder have the right to spend laying the weld, making SMAW among the least reliable welding processes.
