Cobalt based surfacing welding wire is mainly used for surfacing repair of worn parts of chemical equipment and various mechanical equipment. Such as metallurgical machinery, mining machinery, turnout, jaw plate, bucket, shovel teeth, engineering quarry and other brick machine cutters, screw, mixer blades, fan blades, mineral processing machinery, engineering machinery, building materials
Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.
Resistance welding is a method used for splicing a stranded wire, and is best for materials like nickel or stainless steel. While this is a relatively low cost method, there is high heat involved, which may have a tendency to anneal wires, and cause increased electrode …

1 advantages FCAW with CO2 gas protection welding of all virtues, and the following advantages: (1) high production efficiency In the flat position, flux cored wire melting speed of about 10% higher than solid wire, more than 50% higher than arc welding; in other positions, the deposition rate of flux cored wire than solid wires high above one times, 1-3 times higher than manual arc welding.
Recent transitioning in the wire bonding industry has seen a preference in copper over gold for use in the wire bonding process, the reason being that the cost of gold is rising. Despite there being concerns that copper is less reliable due to its hardness and susceptibility to corrosion, copper wire can be used at smaller diameters while performing identically to gold, making it more cost
welding-brazing (LWB) process using a Mg-Al-Zn based welding wire. The influence of the process heat input on microstructure and mechanical proper-ties of the dissimilar joint was investigated. Metallurgical bonding of immisci-ble Mg and Fe couple was
