2020-8-9 · Wire feed rate and hot wire current Attempting to push the deposition rate through increased wire feed rate will likely reduce quality. A rate of 150-180 IPM of.045” wire is typical for nickel based materials. The hot wire current should be maintained to approximately 10-20 Amps below the melting point of the wire.

TIG Vs STICK Welding: Which One Is Best And Where …

2020-8-8 · However, as mentioned above, tungsten has a very high melting point. Thus, the electrode does not melt in TIG welding. Instead, you have to use your hand to feed a filler rod into the weld pool. Mostly you hold the TIG torch with one hand and the filler rod with the other. This is why TIG welding is considered a bit more challenging than the

FAQ: What is the Melting Point of Mild Steel?

A high melting temperature means that mild steel becomes more ductile when heated, and it is therefore suitable for forging. This makes mild steel a very versatile material which is suited to a huge range of appliions – including in structural projects, a good example of which being the use of reinforcing bar in cast concrete. Typically

Why and How to Spot Weld With TIG Welder – …

Another reason to use a TIG welder to spot weld is if the material cannot handle high amperage. If the metal is exceptionally thin or has a low melting point, most welding methods will burn a hole through the material instead of creating a weld. The variability of a TIG welder allows for the joining of metals to fragile for other processes.

Welding techniques explained – Engineering Update

TIG welding uses a non-consumable tungsten electrode and has an extremely high melting point which means that TIG electrodes can heat other metals to their melting points without themselves melting. Argon and helium are the main shielding gases used in TIG welding. In some appliions, however, a mixture of the two gases can prove advantageous.
