A welding engineer is a type of materials engineer concerned with all aspects of welding that lead to the manufacture of a product. Welding is the process of using a combination of pressure and heat to fuse separate pieces of metal into one piece. These engineers may research more effective welding techniques or design more efficient equipment to aid in the welding process. They may also oversee manufacturing processes to ensure quality control or evaluate inspection procedures.  2, record 1, English, - welding%20engineer

G. Cotter Enterprises, Inc. has made tremendous advancements toward a finely tuned microwelding process. Microwelding originated with the mold makers needs in mind. [Since it is an] ultra sensitive method of welding, this skill is now applied to medical parts, electronic components, sensitive finished machined surfaces, polished surfaces, and any surfaces that would not lend themselves to conventional welding. The science behind microwelding is due to the tighter control of the arc in close spaces. The less heat added to the part, the least amount of distortion will result. Minimal sink(sink marks on the material surface due to melting into the base metal) is maintained through this process. Ultimately, precision microwelds lead to less rework, which in turn assist in lower cost for machining. In fact, many microwelds can be finished by hand.  1, record 2, English, - microwelding

In most steels it is desired to eliminate the particles formed by the reaction of the deoxidizer with the oxygen.... Free machining steels are exceptions where many small uniformly distributed particles of certain types are desired. These particles lubricate the cutting tool, prevent welding of the cut chip to the tool tip, and cause the chip to break into short pieces. Additions of lead, sulfur, manganese sulfide, selenium, and tellurium to the steel improve the machining properties of steels in this manner.  1, record 3, English, - free%20machining%20steel
