İngilizce Metin Now that we’re set here for the long haul, we’re considering repurposing some of the old factories here to suit our current needs. Which means we could use some help getting them fixed and fully stocked. Türkçe Çevirisi Artık burada uzun bir yol için hazır olduğumuza göre, bazı eski fabrikaları mevcut ihtiyaçlarımıza göre […]

İngilizce Metin We cannot produce a definitive guide on how to become a TIG welder in this chapter but a few of the more important points are worth including. The use of inert gas prevents oxidation in the weld but it does not provide the cleaning action that a flux would. For that reason, the […]

İngilizce Metin A ‘Backing Bar’ is normally recommended to control the weld penetration and prevent distortion. A Backing Bar is normally included as a part of the welding fixture and may be grooved to produce a desired bead shape. The bar is normally made of copper and, in some processes, it may be water cooled […]

İngilizce Metin The process requires the use of a filler rod and a range of rods are provided for tungsten arc welding. There is no special joint preparation required for butt-welding metals up to 1/8in thick, and aluminium alloys up to 1/4in thick, in that the edges do not require bevelling. When joints are un-bevelled, […]

İngilizce Metin The tungsten electrode has a melting point of over 3,300’C and is non-consumable. The torch can accept a range of electrode sizes and configurations to suit different gauge materials. The electrode is fitted into the torch so that the tip projects about 1/8 in beyond the ceramic shield for butt-welding and slightly more […]

İngilizce Metin For example, it is left on continuously when welding aluminium or magnesium with AC current but it may also be used to initiate the arc when preparing to weld steel and is then turned off whilst DC current is used to conduct the weld. A foot pedal may be provided that incorporates a […]

İngilizce Metin When the equipment is used with AC current, the continual current reversals produce only moderate heating of the electrode whilst achieving a reasonable penetration in the weld area. To avoid loss of the arc during current reversals where the current cycles through zero, a surge injector may be fitted to the equipment. Alternatively, […]

İngilizce Metin However, this arrangement does not easily disperse the type of oxides encountered with many light alloys. A positive DC electrode (Americans call this reverse polarity) tends to become overheated so AC current is used for aluminium and its alloys where the current reversals will clear the oxides on the positive half cycles. I […]

İngilizce Metin TIG equipment can be used with either DC or AC current. DC current is normally used for welding carbon steels, low alloy steels, non-corrodible and heat resisting steels, stainless steels, nickel alloys, copper alloys, Nimonic alloys and titanium. When using DC, the electrode is normally made the negative (Americans call this straight polarity) […]

İngilizce Metin The equipment consists of a welding torch that is connected to a supply of the chosen inert gas and to an electrical current regulator. Argon is stored under pressure in a blue cylinder whereas helium is stored in a brown cylinder. The inert gas is supplied to the torch through a regulator on […]

İngilizce Metin The welding speed is higher than in gas welding and because there is no oxidation in the weld area, there is no need for a flux. This means there will be no flux residue to clean off so the finishing process is much cleaner and quicker than gas welding. However, the gas does […]

İngilizce Metin The tungsten electrode is encircled by a ceramic shield that is supplied with a flow of inert gas and is designed to direct it around the arc and on to the weld site to shield it from atmospheric oxygen and nitrogen and thus prevent oxidation. This makes the process particularly suited for welding […]
