Welding and Fabrication Engineering

As we know well, welding is an ancient art which is prevailing since the Bronze Age. It is the process used to join materials, usually metals or thermoplastics by melting the work pieces. The molten material is then allowed to cool and become a strong joint, with pressure sometimes used in conjunction with heat to produce the weld. Welding produces a secure, strong joint that cannot be compared with other methods. In today’s world, welding engineering has become an arising need in job market. Welding and Fabrication Engineering Technology is structured to support welding and joining operations. Here engineers pass plans and projects to mid-managements personnel who are supposed to carry out the planning, organization and delivery of manufacturing projects.

The major emphasis lies on developing skills needed to lead projects and interface with engineering and development teams. Welding and Fabrication engineering involves the techniques of utilizing welding and fabrication methods in an efficient way. Fabrication is an industrial term that refers to building metal structures by cutting, bending and assembling. The cutting part can be done by sawing, shearing or chiseling. The bending is done via hammering, press brakes or similar other tools. And finally, assembling is done via welding, binding with adhesives, riveting, or threaded fasteners. Fabrication and machine shops that use engineering techniques have overlapping capabilities, though they generally concentrate on metal preparation and assembly. Fabrication and welding engineering generally covers essential fabrication and welding skills like safety, engineering communications and teamwork.

Welding fabrication engineers make, join and repair metal parts for machinery and equipment such as motor bodies, trailer units, containers, truck frames and bridges. The fabricator is the one who employs or contracts out steel detailers to prepare shop drawings, which the fabricating shop will use for manufacturing. Manufacturing engineers will program CNC machines as needed. Welding is considered to be the main focus of steel fabrication. Initially the formed and machine parts will be assembled and tack welded into place, then rechecked for accuracy. In case if multiple weldments have been ordered, a fixture might be used to locate parts for welding. The welder then completes welding as per the engineering drawings. Special precautions might be needed to prevent warping of the weldment due to heat. This includes re-designing the weldment to use less weld, welding in a staggered fashion, covering the weldment in sand during cooling. Using a stout fixture and straightening operations after welding.
