is a form of resistance welding. Resistance welding is a welding process that uses electric current to generate heat and melt the metal at the weld area. Unlike other welding methods that use filler materials or gas shielding, resistance welding does not require any additional materials or protect...
Brazingis a method of bonding that involves using a filler metal with a melting point lower than the base metals being bonded. Brazing joins metals by melting a filler metal between them using capillary action. This is different from welding, where the base metals themselves melt to create the...
In MIG/MAG welding the arc is established when the filler material touches the surface of the workpiece and a short-circuit is generated. Then efficient short-circuit current melts the end of the filler wire and a welding arc is established. For a smooth and durable weld, the welding arc s...
Welding can be broadly classified into three groups according to the joining method used: Fusion welding melts base materials or a base material and a welding rod used for joining the base material (filler material); pressure welding melts base materials mechanically through friction, pressure or ...
Choosing Filler Materials for DSS; What is the X-Factor? (cover story)The article presents two questions and answers related to welding including recommended filler material for GTAW to weld SA-790 4-in. schedule 40 duplex stainless steel and the meaning of X-factor in welding equipment....
No filler material is used. In stud welding, an arc is briefly struck between the face of the stud and the work piece; both parts start to melt and are then joined. Depending on the nature of the ignition method, a distinction is made between drawn‐arc stud welding and stud welding ...
What is electrode extension in welding? Electrode extension (stick-out length) isthe length of the filler wire that extends past the contact tube. This is the area where preheating of the filler wire occurs. It controls the dimensions of the weld bead since the length of the filler wire ext...

Smart MIG welders require less skill from the beginner: The most user-friendly welder makes it easier for the beginner to learn. The welding machine supplies powers, shielding gas, and filler through the MIG gun, allowing the beginner to concentrate on grasping the basic joints and welds. Take...
All welding variable must be recorded during the welding. Please note in WPS you have the range but you will not have a range in the PQR, and you need to record a single value for each specified variable.The ASME Section IX Training Course is 2 days video training course and available ...
