Tungsten Inert Gas(TIG)
How does a TIG welder work?
TIG stands for tungsten inert gas and is technically called gas tungsten arc welding (GTAW). The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. An inert gas, typically argon, protects and cools the tungsten and weld puddle. TIG welding is similar to oxy-acetylene welding in that you use a filler material for build-up or reinforcement.
In race car fabrication, we use TIG welding for aluminum and 4130 chrome-moly steel. If you are going to weld either of these materials, you need a quality TIG welder. Miller offers products to accommodate anyone — from a home hobbyist to an advanced user.
If you have ever welded with an oxy-acetylene torch, you can easily weld with a TIG machine. The TIG process uses an electric torch, and the welder hand feeds filler rod into the molten puddle.
The ability to soft start and soft stop the heat makes the TIG process different from other types of electric welding. Some people like the accelerator pedal to control the heat if they are working on a bench and others like fingertip remotes on the torch if they are working in out-of-position areas. The remote adjusts the heat while you are welding.
Holdingham is a hamlet in the civil parish and built-up area of Sleaford, in the North Kesteven district of Lincolnshire, England. It is bisected by Lincoln Road (B1518) which joins the A17 and A15 roads immediately north of the settlement; those roads connect it to Lincoln, Newark, Peterborough and King's Lynn. Sleaford railway station is on the Nottingham to Skegness (via Grantham) and Peterborough to Lincoln Lines.
Prehistoric and Romano-British artefacts have been uncovered around Holdingham. There was an early and middle Saxon settlement, which appears to have disappeared in the 9th century. The current settlement's Old English name suggests a pre-conquest origin, though it was not mentioned in the Domesday Book and appears to have formed part of the Bishop of Lincoln's manor of New Sleaford. Holdingham probably functioned as the agricultural focus of the manor, while New Sleaford (0.9 miles or 1.5 km south) was encouraged to expand as a commercial centre. The land was ceded to the Crown in 1540 and was acquired by Robert Carre in 1559; it passed through his family and then, through marriage, to the Earls (later Marquesses) of Bristol, who owned almost all of the land. Enclosed in 1794, it remained a small, primarily agricultural settlement well into the 20th century.
The late 20th century brought substantial change. Holdingham Roundabout was built immediately north of the hamlet in 1975 as part of the A17 bypass around Sleaford; the roundabout also accommodated the A15 bypass which opened in 1993. After Lord Bristol sold the agricultural land around the hamlet, major residential development began; private suburban housing estates were completed either side of Lincoln Road between Sleaford and Holdingham in the 1990s and early 2000s. The hamlet thereby merged into Sleaford's urban area. Further developments took place in the 2010s and more housing has been approved for building in the 2020s on land between Holdingham and The Drove to the south-west.
Holdingham had its own chapel in the Middle Ages, but this was abandoned c. 1550; its site has not been identified securely. It has had a public house since at least the early 19th century, serving drovers bringing their cattle from Scotland to London. The hamlet now has petrol filling stations on the roundabout and Lincoln Road, as well as fast food restaurants, a hotel, a café and a nursing home – all opened since the middle of the 20th century. The nearest schools and other public services are in Sleaford. The hamlet was anciently part of the parish of New Sleaford; in 1866, the civil parish of Holdingham was established but in 1974 was merged into Sleaford civil parish. The hamlet now lends its name to a ward in North Kesteven, although the boundaries differ from those of the old parish. The ward had a population of 2,774 in 2011.
