NMTS seeks out the most qualified inspectors with excellent safety records and retains many outstanding inspectors on our permanent staff. We do a thorough background check on all inspectors prior to mobilizing them to a job site. Welding. Welding processes are conveniently divided into two classes: . fusion welding and solid state welding. . . During fusion welding a portion of the base materials to be joined is melted and mixed, often with the addition of a filler metal, forming a solid joint after subsequent solidification. . History of Welding. Welding was used in the construction of the iron pillar in Delhi India, erected about 310 AD and weighing 5.4 metric tons. . History of welding. Welding, was transformed during the 19th century. In 1802, Russian scientist Vasily Petrov discovered the electric arc and subsequently proposed its possible practical applications, including welding.. Tig and Mig welding. By: Luke Woroniecki.

Welding Metallurgy. nature OF WORK. - Welders. , cutters, . solderers. , and . brazers. held about 337,300 jobs in . 2010. -Welders will either work outdoors or in a confined space to contain sparks.. - They wear safety shoes, goggles, masks with protective lenses, and other equipment to protect from burns and falling objects. . Covered in Subpart H, but an integral part of welding, cutting and brazing. Compressed gases-hazards. compressed energy. flammable, asphyxiants, oxidizers. Gases are used for cutting, brazing and “shielding” the weld. Joining and Assembly. Joining . - . welding. , . brazing. , . soldering. , and adhesive bonding. These processes form a permanent joint between parts. Assembly - mechanical methods (usually) of fastening parts together. Flexible Manufacturing. Copyright © Texas Education Agency, 2013.
