They work well on AC sine wave welding and form a solid balled tip that results in a stable arc. Welders can grind the tip of these electrodes to a sharp point and enjoy and stable arc that last a long time. The final weld puddle is cleaner since the electrode leaves fewer deposits, and thorium allows for easier arc starts and higher current-carrying capacity. Welders can work on projects that include thin aluminum, titanium, carbon steel, stainless steel, and nickel.
Since thorium is radioactive, welders remain cautious about using these electrodes. Since it can weld carbon steel, stainless steel, nickel alloys, and titanium, some welders have found that it works well as a replacement for thoriated electrodes.
Ceriated is not recommended for welding at higher amps since the heat can change the composition of the electrode. Welders prefer to work with Ceriated electrodes at lower temperatures for small, precise parts, pipe fabricating, and welding thin metal. It can weld steel from a square wave power source and it offers reliable arc starts and arc stability.
Due to its durability and versatility, some welders use Lanthanated in place of thoriated since there are no radioactive elements in the metal. Since the zirconium is a strong metal that resists cracking, it produces a stable arc and resists contamination. They are best for welds with titanium alloys, copper alloys, nickel alloys, and non-corrosive steel. Blue electrodes are highly effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, titanium alloys, low-alloyed steels, and non-corrosive steels.
They perform best with titanium alloys, copper alloys, magnesium alloys, aluminum alloys, nickel alloys, non-corrosive steels, and low-alloyed steels.
Extremely long lasting and highly durable, these electrodes are a staple in DC welding applications. These red electrodes are perfect for copper alloys, nickel alloys, titanium alloys, and non-corrosive steels.
Green electrodes are excellent for AC weld projects related to magnesium alloy or aluminum alloys. What is purple tungsten used for? Re: Purple tungsten The electrodes offer excellent ignition characteristics and consistent welding properties.
They are universal and suitable for all applications in the whole range of DC and AC welding for non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys. How do you end a tungsten ball? Now, start up the welder.
Again, let the electrode rest. Is thoriated tungsten dangerous? When TIG welding stainless steel and mild steel, and most other metals you have a direct-current DC arc running between the tungsten electrode in your torch and the workpiece.
Why welding of stainless steel is difficult? The main problem when welding this ferritic stainless steel is poor HAZ toughness. Excessive grain coarsening can lead to cracking in highly restrained joints and thick section material.
When welding thin section material, less than 6mm no special precautions are necessary. Which welding is best for stainless steel? This welding process creates a low heat input, which makes it perfect for thin material. How do you prepare stainless steel for welding? The next step is to remove any oxides on the surface of the metal.
