Shielded Metal Arc Welding

Versatile, field-proven stick welding for structural and high-stress applications that must withstand heavy loads and sustained stress.

Overview

Versatile welding, built for stress

Shielded Metal Arc Welding — commonly known as stick welding — uses continuous-fed consumable electrodes with alternating current, running in both automated and semi-automated configurations. Its flux-coated electrode shields the weld pool as it burns, forming a slag layer that protects the cooling joint.

SMAW's versatility and simplicity make it adaptable across a wide range of applications and site conditions, and it remains our process of choice for structural and high-stress joints that must withstand heavy weights and sustained loading. One of the major factors behind a high-quality SMAW weld is welder skill — which is why every SMAW welder on our team is individually AWS certified.

How It Works

How an SMAW joint is made

A flux-coated stick electrode process proven across decades of structural welding.

1

Electrode Selection

A flux-coated stick electrode is selected to match base metal and joint requirements.

2

Arc Strike

The welder strikes the arc directly between the electrode tip and the workpiece.

3

Flux Coating Shielding

The electrode's flux coating burns to shield the arc and forming weld pool.

4

Slag Formation & Bead Deposit

Molten flux forms a protective slag layer over the newly deposited weld bead.

5

Slag Removal

The cooled slag layer is chipped and brushed away to expose the finished weld.

6

NDE Verification

Non-destructive examination confirms weld integrity before acceptance.
