Miller Electric is an American arc welding and cutting equipment manufacturing company based in Appleton, Wisconsin. Miller Electric, has grown from a one-man operation selling products in northeastern Wisconsin to what is today one of the world's largest manufacturers of arc welding and cutting equipment. [1]
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
A continuous or pulsed laser beam may be used depending upon the application. Millisecond-long pulses are used to weld thin materials such as razor blades while continuous laser systems are employed for deep welds. LBW is a versatile process, capable of welding carbon steels, HSLA steels, stainless steel, aluminum, and titanium. Due to high ...
Typically, the equipment used for SMAW consists of a step-down transformer and for direct current models a rectifier, which converts alternating current into direct current. Because the power normally supplied to the welding machine is high-voltage alternating current, the welding transformer is used to reduce the voltage and increase the current.
Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
Robot welding is the use of mechanized programmable tools , which completely automate a welding process by both performing the weld and handling the part. Processes such as gas metal arc welding , while often automated, are not necessarily equivalent to robot welding, since a human operator sometimes prepares the materials to be welded.
