Spot cum Projection Welding Machine

Gaidu Electricals Pvt Ltd offers a Spot Cum Projection Welding Machine. Resistance fastener welding, generally called projection welding, is similar to resistance spot welding. However, in the spot welding process, the size of the contact surface of the electrode cap tip determines the current flow, whereas in projection welding, the current flow is constricted to the embossed or machined projection. Projection welding passes a high current at low voltage through the electrodes to the welding area. As the machine cycles, exert pressure on the metal, a joint is formed and coalescence occurs. The heat balance for projection welding is affected by the following factors: projection design and location; thickness of the sheet to which the fastener is attached; thermal and electrical conductivities of the metals being welded; heating rate; and electrode alloy type. Gaidu Electricals Private Limited is one of the leading manufacturers, exporters and suppliers of multi process welding systems and inverters. The range includes inverters, MIG/MAG welding machines, welding positioners, arc welding sets, DC welding rectifiers, projection welding machines, metal gathering machines and seam welding machines. The company also offers clients TIG welding machines, DC TIG welding machines, submerged arc welding machine and pneumatic spot welding machines. These are appreciated by the clients for low maintenance, assured reliability, low noise, application specific design and extended durability.
