Welding Table – Why You Need One

There are basically two types of FCAW

Flux cored arc welding (FCAW) is a type of electrical welding that utilizes the reaction between the filler metal and the welding wire to produce a hot, sparking and melted metal product. This highly efficient welding technique is one of the most widely used in the construction industry. It’s simple to use and provides a fast production rate. There are basically two types of FCAW – the direct fed system and the alternating current (AC) system.

The difference between these two methods lies in the source of power. AC welding uses electric currents while DC welding uses conductive welding cables. AC welding cables carry higher deposition rates than do the DC cables. Therefore, AC welding machines are generally more profitable for manufacturers who have lower overhead costs.

Flux cored arc welding (FCAW) is a simple yet highly efficient process for welding metals

Flux cored welding requires a continuously-feeding consumable fluid tubular electrode comprising a flux and a continuous-voltage or (CCV) power supply. Flux cored welding is sometimes also known as ‘continuous feeding’ because it involves feeding the filler metal (usually steel) into the welder at a faster pace, which eliminates some of the manual work. The fluid expansion rate of the filler metal is also faster with the use of a continuous feeding system. However, the use of fluid infusion can be problematic as well as messy if it occurs without the proper fluid cleaning equipment.

In order to achieve a good welding performance and a consistent weld, the welder needs to position himself in a welding position that provides a stable base and seat. In a typical welding position, the welder is sitting on a welding bench with his hands held above his head. The seat should not only provide a comfortable welding position, but also should be equipped with a shielding gas source and adequate ventilation. The welding bench itself should have a sufficient amount of shielding gas.

Proper ventilation also allows better oxygen flow

Depending on the type of welding process to be performed, the welder may be required to stand in certain positions. Usually, the welder will stand on a welding pedestal. This positioning is essential for proper safety procedures. It enables the welder to maintain his balance and provide a firm support for his arms, hands and feet while welding. Welding pedestals also allow better access to and circulation of air. Proper ventilation also allows better oxygen flow, minimizing fatigue, skinning and other unwanted welding fumes.

In addition, standing on a welding pedestal also gives a much more even weld, with no parts becoming over heated. Many welding shops use a variety of stand racks to provide these facilities. For example, one type has a slant plate that provides the welder easy access to both the legs and the wire feed. Another option has an adjustable pedestal that lowers or raises the welding work table. There are some modern designs that incorporate a hydraulic lift system for convenience, as well as providing adjustable legs and a sloped floor.
