Solid wire welding is a type of Gas Metal Arc Welding (GMAW) that uses a solid metal wire as the consumable electrode. The process involves melting the base metal and the filler metal (the solid wire) together to form a strong joint. The filler metal provides additional material for the joint, making it stronger than the base metal alone. Solid wire welding uses shielding gas to protect the weld pool from contamination.

Solid wire welding guarantees stronger welds because of higher deposition rates. The consistent deposition rate provided by this method ensures that the weld is structurally sound with fewer weak points, thus giving the product a longer lifespan. Furthermore, solid wire welding reduces spatter and porosity during the process compared to other methods like stick welding, which leaves behind slag that needs cleaning up when done. Solid wire welds also have an improved appearance since they produce smooth finishes without blemishes or surface imperfections. Additionally, better quality welds produced by solid wire ensure less rework, saving time and money. The versatility of solid wire welding makes it an ideal choice for different kinds of projects with varying material thicknesses. Overall, this type of welding offers a cost-effective option that requires less skill than other methods making it highly accessible even to beginners.

Flux cored arc welding (FCAW), also know as dual shield welding, is a semi-automatic arc welding process that is similar to metal active gas (MAG) welding. FCAW uses a continuous wire fed electrode, a constant-voltage welding power supply, and similar equipment to MAG welding. Flux core arc welding usually uses a shielding gas similar to that used by MAG welding, but it can also be performed without a shielding gas. It is more productive than MAG welding.

It is a flexible welding process suitable for all position welding, given the correct filler material and flux composition. Being highly productive due to the high deposition rates, it provides high quality welds with a good appearance. The high welding speed and portability of this welding method means that it is widely used in construction. This is further supported by the fact that the process can be readily performed outdoors, even in windy conditions.

Since it can be used to for a range of alloys, plain carbon, stainless and duplex steels, flux cored arc welding is also frequently used for surfacing and hardfacing.

Metal-Cored Arc Welding (138) uses the heat generated by a DC electric arc to fuse metal in the joint area. Here the arc is struck between a continuously fed consumable filler wire and the workpiece, melting both the filler wire and the workpiece in the immediate vicinity. The entire arc area is covered by a shielding gas, which protects the molten weld pool from the atmosphere.

MAG 138 is applied mainly to welding carbon, carbon-manganese and alloy steels, but may also be used for welding some stainless steel grades. Like MIG welding, success hinges on selection of the right consumables, power source, polarity on the power source, shielding gas and application technique.

A hull fitter is part of a shipbuilding team. As a fitter for the ship, you must cut and attach enormous sheets of metal which form the hull or outside of a ship. In this position, you have to have experience and training in welding. You will also have to operate with blueprints in a workshop atmosphere, cutting and welding metal sheets. You also need to work on the ship, frequently at high altitudes, to set the sheets into place and weld them to the ship’s frame. A fitter carries out a highly strenuous job. They typically carry up to 50 pounds of stuff (23 kg) frequently. The task might involve a high escalation into the air to solder or weld metal to the ship’s framework.

Marine Pipe Fitter. Piping Technician to work on a wide range of Maritime Piping Systems and related products. Ships have a maze of pipes that carry gas, steam water and other vapours in order to run. The trade`s people that connect assemble and maintain these pipe systems are called marine Pipe Fitters. Pipe Fitters are involved in the installation and maintenance of Fire Fighting, Bilge, Hydraulic Steering, sanitary, potable water, Hot water heating, fuel, and exhaust piping system on Ships. Marine Pipe fitter fit into the group of “pipe trades,“ which deals with the installation, maintenance and repair of piping systems.

These personnel also withstand weather, from high heat to harsh cold, when they operate on drydocks. To become a shipfitter, a person needs to be able to squat, and crawl when making templates or sizing metal.
