What is Heliarc Welding

Now you might be asking yourself “when is it more appropriate to use the TIG welding process?”. Well, that mostly depends on the type of job you’re working. To being with, TIG welding is harder than most other processes like MIG welding. TIG welding needs a lot more control than other processes since you have to focus on things like timing, electric current, heat, and pressure. It’s this reason that TIG welding is often best left to a computer numerically controlled welding machine.

When deciding to use TIG welding it is important to pay attention to the thickness of the two metals that you are joining. Thicker metals are harder to weld together by just heating them until they weld together. The thicker they are the more heat and energy are needed to get them to the melting point. This can make TIG welding a lot less efficient or cause heat stress cracking. With heat stress cracking you could compromise the integrity of the weld and/or it’s corrosive resistance. With these points, it is obvious that Heliarc or TIG welding is best for joining thinner metals.

One of the best things about TIG welding though is the amount of control and precision you are given. The welder is given the ability to use a remote control switch or footswitch to control the heat and amperage. The actual TIG welder is also thinner giving welders more control. With all these, welders using the TIG welding process can achieve excellent precision and more detailed welds. Which is something all welders want.
