2022年10月11日 · In TIG welding, a tungsten electrode in a hand-held torch heats the metal being welded and a shielding gas (commonly argon) protects the weld puddle from airborne contaminants. The tungsten is a non-consumable and the filler metal is added via a filler rod in the operator’s other hand.

2022年10月5日 · TIG welding was developed to efficiently join aluminum and magnesium alloys, and pure tungsten made sense at the time, since it has the highest melting temperature of all metals. In those days power sources were transformer based, and pure tungsten could accommodate welding in the AC mode, which is the standard for aluminum and magnesium.

We'll talk about independent ac waveform control, gas selection, TIG welding Aluminum with DC TIG, and techniques for welding anodized aluminum. JlGC0PtSPBM 93680479-3399-4237-aad6-3ee6fd8aeb66

2021年9月1日 · The TIG welder in action. The rod is being fed with one hand while the other guides the torch. A comfortable position here means a lot to weld quality. This is the type of weld joint you should avoid. All these tubes converged at one point and were tack welded into place. It is virtually impossible to reach the inside edges of the tubes.

2018年9月10日 · With the TIG process, the heat comes from an electric arc that streams between the electrode in a hand-held torch and the metal being welded. The arc and molten metal are shielded by an inert gas, which protects the electrode and base metal from oxidizing. Filler rod is usually added to the puddle of molten metal as the weld progresses.

2020年4月8日 · Most of the work I’ve done with plate and extrusions has been with 6XXX series aluminum — and 5356 filler rod is the best match for these alloys. 5XXX series aluminum is available in a wide range of thicknesses, from thin sheet to heavy plate, and either 5356 or 4043 filler rod can be used for these alloys.

2019年4月5日 · The silicon bronze rod’s lower melting point makes it ideal for joining together thin sheet metal, galvanized steel, and nuts and bolts, too. It’s nice for sheet metal work because the lower melting temps means less heat, which equals less warping when compared to TIG with, say, an ER70 rod.

2009年8月1日 · Learning to TIG aluminum. TIG welding aluminum doesn’t need to be intimidating. With a little practice — and some basic best practices to help beginning welders — you can produce the results you want. Follow our four steps below to practice and advance your TIG welding skills with aluminum. Step 1: Watch hand and torch placement

2009年8月18日 · Balance control is also an important feature when TIG welding aluminum, as it can be used to increase or decrease the cleaning action to remove surface oxides. Most aluminum TIG welding repairs won't exceed 80-150 amps, so a 200-amp class power source matched to a 250-amp water-cooled or 200-amp air-cooled TIG torch will suffice.
