What is the main difference between filler rods and electrodes?
Filler rods are used to add metal to a molten weld pool during the welding process and electrodes actually have electricity running through them to deposit metal into the weld with the exception of TIG welding where the tungsten electrode is used solely for heat.... Hope this was helpful
What welding process uses a non consumable electrode?
consumable is when the rod or other metal is also used up in the weld, like common mig welding. Non consumable would be like forms of tig welding that don't use any rods or other metals to join the 2 materials together. This is the Distance
Which electrode is using for cs and ss combination weld?
309l
What is the role of silicon in welding electrodes?
Silicon is used to lower the viscosity of the weld puddle. This allows better flow of the molten weld puddle.
What is welding electrode coating do?
It melts. Avoid moisture. To cover the weld. ------ Plus adds alloying ingredients, determines the type of electrical current to be used (AC - DC or either), slows the cooling rate of the puddle to temper the weld, tells you what position you can weld in (flat,horiz,vert,overhead), protects the molten puddle from harmful gasses in the air by creating smoke and slag, determines how much amperage you will need to use, shapes and contours the weld bead and much more.
What is a leading electrode angle for in welding?
what characteristics does the weld bead have when weaving the electrode
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
How does length of gas nozzle effect mig welding?
The legth of the gas nozzle can affect the MIG welding process because it modifies the "electrode extension" or so called stickout. The longer the nozzle the longer electrode extension needed to keep the arc away from it thus the value od the welding current and arc voltage changes. These changes will have a great effect on the weld.
What is manual arc welding?
Everybody used to call it "stick welding". MMAW Manual Metal Arc Welding is the correct nomenclature. The "sticks" are electrodes held in an electrode holder connected to a power supply. Establish an arc between the end of the electrode and the metal and move across the joint. As you weld the electrode is consumed. Discard the "stub", insert a new electrode and continue.
What is polarity in welding?
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
What is the difference between a consumable electrode process and a non consumable?
Consumable electrodes actually form the filler metal of a weld. Stick and wire are examples of a consumable electrode. TIG on the other hand only produces the arc for the weld, and the filler metal is fed into it. The tungsten (the electrode) of a TIG torch does not enter the weld.
How do you weld spring steel?
hello what is filler metal (electrode) for welding of spring steel like 1.5142, 1.5225, 1.7138? regards
What is excess weaving in welding?
excessive We were taught 2-1/2 times the width of the electrode was maximum. ie: 5/16" width weld bead for 1/8" electrode.
What is the effect on the weld if the electrode is held too close to the material being weld?
the rod will simply stick to the material being welded!
Why Carbon dioxide is used in MiG welding?
MIG (Metal Inert Gas) and MAG (Metal Active Gas) welding requires an external shielding, since the electrode does not have a coating of its own.Higher carbon dioxide content increases the weld heat and energy when all other weld parameters (volts, current, electrode type and diameter) are held the same. Higher levels of CO2 allow deeper penetration of the weld as well.
What is the welding for MIG welding?
mig welding is Metal Inert Gas welding. it typically uses Constant voltage DC+ current. It uses a wire feeder that supplies the electrode to the weld puddle and shields the molten weld puddle with inert gas (argon/co2 blend). Filler wire and shielding gas depend on the metal being welded.
What determines whether polarity of a welding machine is set up for DCEN or DCEP?
The electrode. In some cases thin materials weld better with DCEN.
