PTC has air type resistance spot welding, gas metal arc welding, gas tungsten arc welding and ordinary arc welding machines. Air type resistance spot welding is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current flow. Work-pieces are held together under pressure exerted by electrodes. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The sheet metal that can be spotted ranges from 0.5mm to 3.5mm. The machine offer high efficiency welding for sheet metal and can be adjusted to access a variety of work piece shapes. Gas metal arc welding is sometimes referred to by its subtype’s metal inert gas (MIG) welding or metal active gas (MAG) welding. It is a semi automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun and we use carbon dioxide as a semi-inert gas. Gas tungsten arc welding is frequently referred to as TIG welding and is commonly use in high quality welding process. It has become a popular choice of welding process when high quality, precision welding is required. For ordinary arc welding, this will be used for the fabrication of our home furnishings.
