释义 | > as lemmasMIG welding In full MIG welding: a form of metal arc welding in which the electrode and the welding surface are shielded by an inert gas such as argon or helium, so as to avoid the formation of oxides. Also attributive. ΚΠ 1960 McGraw-Hill Encycl. Sci. & Technol. XIV. 467/1 Inert-gas metal-arc welding with consumable, continuous electrodes (called MIG welding, for Metal Inert Gas) requires no flux and produces welds without a slag cover. The arc is in an atmosphere of argon or helium supplied at 5–100 ft3/hr from the gas cup of the torch. 1963 Encycl. Engin. Materials & Methods at Arc welding Inert gas shielded-arc welding... This process is often called inert-gas welding for short. There are two major subdivisions: TIG and MIG... Inert gas spot welding is a modification of the basic TIG and MIG welding methods. 1971 Engineering Apr. 88/1 Specialists in..metallic arc, tungsten arc (TIG) and metal inert-gas arc (MIG) construction. 1978 Jrnl. Royal Statist. Soc. B. 40 272 The first set gives fracture toughnesses of MIG welds. 1988 Tool World 147/2 Mig welding..is a simple process which does not require the technique of brushing electrodes against the surface. 1989 A. C. Davies Sci. & Pract. Welding (ed. 9) I. i. 36 Argon..is extensively used..in the welding of aluminium, magnesium, titanium, copper, stainless steel and nickel by the TIG and MIG processes. 1991 Metalworking Production Sept. 29 (advt.) Robotic mig and spot welding. 1994 Barbados Advocate 10 Aug. 33/6 (advt.) Welding equipment. MIG welders... Plasma Cutters [etc.]. 1998 Amer. Machinist 142 58/2 Anyone working with pulsed MIG clearly understands how these variables affect the arc... Pulsed MIG requires the operator to maintain an arc gap, which helps decrease the amount of spatter produced. < as lemmas |
