What else can I help you with?
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.
The electrode holder used for shielded metal-arc welding may not be used carbon arc welding?
Any electrode holder that will accommodate the size of rod can be used. Twin Carbon Arc Welding requires a specific holder. Air Carbon Arc Gouging requires a special holder that also supplies a stream of air.
What type of welding process is used to join dissimilar metal?
friction welding can be used to join dissimilar metal. Also depending on the metals most arc welding processes and oxy-fuel can used. It's just a matter of using the correct filler material or electrode.
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 arc diameter in welding?
Depend upon dia of electrode & Arc length between Electrode tip and job surface.
What is the proper amount of arc length when welding?
A rule of thumb is - the arc length should be the same as the diameter of the electrode. 3/32" electrode = 3/32" arc length. 1/8" electrode = 1/8" arc length etc. The thicker the electrode coating the shorter the distance from the end of the electrode to the work. Drag rods are contact rods. E-7024 is one.
What is arc in welding?
arc energy is the amps that are comming off from the electrode
What arc welding process uses a consumable stick electrode?
The arc welding process that uses a consumable stick electrode is Shielded Metal Arc Welding (SMAW), commonly known as stick welding. In this process, an electric arc is formed between the coated stick electrode and the workpiece, melting both the electrode and the base metal to create a weld. The coating on the electrode provides a shielding gas and slag to protect the weld pool from contamination. SMAW is widely used for its versatility and effectiveness in various applications.
What is Arc Energy in Welding?
arc energy is the amps that are comming off from the electrode
What is Arc length in welding?
Arc length is the distance from the tip of the electrode to the workpiece.
What is the correct name for covering an electrode?
The correct term for covering an electrode is electrode coating or electrode insulation. This coating is used to protect the electrode from environmental factors and to enhance its performance and longevity.
What is the polarity used for arc gouging?
Arc gouging typically uses direct current (DC) with reverse polarity, where the electrode is positive and the workpiece is negative. This configuration allows for better control of the arc and enhances the removal of metal by concentrating heat at the electrode tip. The reverse polarity also helps in producing a more stable arc and effective metal removal.
