Assessing the nature of the metal Stainless steel is ideal for storing drinks or edible items as it is resistant to corrosion. Normally, welding is only carried out on carbon steel. Carbon steel is capable of handling the excess heat that any welder might accidentally apply to the metal. Consequently,  it is compatible with most available welding machines . And it does not require as much current to run as carbon steel when welding. Due to its high thermal conductivity, aluminium requires an almost uniform supply of heat to prevent the melt pool from drying out. However, high heat input often leads to distortion of the work piece. Aluminium therefore requires more sophisticated welding machines. So we advise you to evaluate the metal you wish to join before selecting a welder.   Establishing the ideal amperage The cost of a welder depends on the current it can produce; thicker metals usually require more current to be welded correctly. Then you need pa...

It is a good idea for an enthusiastic welder to learn about the different types of welding equipment to improve your employment prospects.   A wide range of welding equipment   and accessories are available on the market. Here are some tips on choosing a perfect welding machine.   Refer to the specification sheet Referring to the specification sheet will help you understand a few key factors that distinguish a quality welder from others. For example, a specification sheet can help you measure how many continuous welds a machine can perform in ten minutes.   Analyse compressed gas requirements, if any Different welding processes require the use of different compressed gases. Oxygen, argon and carbon dioxide are the most commonly used compressed gases for a variety of welding procedures.

Direct current is used for MIG/MAG welding. The arc burns between the workpiece and a consumable wire electrode, which is also the source of the necessary filler material and is essentially endless. It is supplied either on a spool or in a drum and is guided to the contact tip by the drive unit. The free wire end is relatively short, which allows a high amperage to be used in spite of the thin wire electrodes. Solid wires or “flux core” wires can also be used as filler metals, depending on the requirements. Solid wires are most often used for MIG/MAG welding. These wires are manufactured by drawing them to the desired nominal diameter from a rolled wire. Flux core wires are manufactured by introducing the powdery filling into a U-shaped strip at one of the production stations. The strip is then sealed by folding or welding it. Different fillings affect the welding process in different ways. The shielding gas flows from a gas nozzle that surrounds the electrode. It protects the arc and ...
