Welding using the SMAW, FCAW and SAW

Stick welding takes its’ name from the shape of the electrode, which looks like a stick. It can be used to weld many types of metals including steel, stainless steel and cast iron.

Stick welding machines provide constant current (CC) using direct current (DC) or alternating current (AC). Direct current operates on different directions based on the polarity. Alternating current switches between directions.

Power in the electrical circuit used to power the weld is measured in amperes. More current or amperage is needed for welding thicker metals or electrodes.



Flux core arc welding usually uses a shielding gas like that used by MAG welding, but it can also be performed without a shielding gas. It is more productive than MAG welding.


Submerged Arc Welding (SAW) is a joining process that involves the formation of an electric arc between a continuously fed electrode and the workpiece to be welded. A blanket of powdered flux surrounds and covers the arc and, when molten, provides electrical conduction between the metal to be joined and the electrode. It also generates a protective gas shield and a slag, all of which protects the weld zone.

Test Pack Works

Test Packs aide the client with the identification and tracking of piping systems against P&ID and Isometric Drawings and can record information to document significant construction completion targets.

The test pack development is based on piping systems, spec changes, piping material and mediums and shall conform to the parameters and requirements set out in the project specifications.

Hydro Test Works

Hydrostatic testing is a type of pressure test that works by completely filling the component with water, removing the air contained within the unit, and pressurizing the system up to 1.5 times the design pressure limits the of the unit. The pressure is then held for a specific amount of time to visually inspect the system for leaks. Visual inspection can be enhanced by applying either tracer or fluorescent dyes to the liquid to determine where cracks and leaks are originating.
