The single filler wires used most commonly have diameters in the range 3.2–4.8 mm; smaller wires are prone to cause random arc wander, particularly with the relatively long electrical stick-outs that are used, and larger diameter wires are more difficult to feed. welding processes Although it is possible to use standard fluxes, special flux formulations with […]

Impact energy is generally assumed to equal the maximum kinetic energy that is due to the acceleration of the flyer plate. Defining impact energy: Energy loss that is due to the bending strain energy in the flyer plate has been ignored in much of the earlier literature, because of its complexity. Recent estimates of energy […]

Manual metal arc welding has been used extensively in the shipbuilding, defence, offshore, and power-generation industries for the fabrication of carbon-manganese and low-alloy steels. An extensive range of MMAW consumables is now available covering the joining requirements of the more important engineering materials as well as repair, surfacing, cutting and gouging electrodes. Areas of development of […]
Read More In weldings, it usually takes place troubles and damages that makes your machine work ineffectively. In this case, maintenance is mandatory and if you know some simple tips to repair or maintain it, it is much economical and faster that celerate the productivity subtantially 1. Drive rolls not clear up or adjusted exactly. The drive roll […]

Wire feeders for constant-voltage FCAW systems are generally simple devices that provide a constant wire feed speed. The power supply provides sufficient current to maintain an arc at the voltage that is preset at the power supply. A change in wire feed speed results in a change in the welding current. Both air-cooled and water-cooled welding […]

There are many types of welding machine but mig welder is popular most. This types of welder is not as many other types because it is wire feed welding machine. Moreover, it is not made use of a stick or electrode. It is more efficient for general welding If you have a desire to buy […]
