Electrofusion welding can be used to weld various metal materials, and the appropriate power source and electrode can be selected for welding according to the actual situation. 3. Can weld thick plates Disadvantages of electrofusion welding
Strength:Spot welding is not a very strong welding process, as it only creates a small weld nugget that may not be able to withstand high loads or stresses. The strength of the weld depends on the size, shape, and number of the weld nuggets, as well as the quality of the metal sheets...
Polarity in welding refers to the direction of electrical flow between the welding power source, electrode, and workpiece. It plays a crucial role in determining the weld characteristics, penetration depth, and overall welding process. In this comprehensive guide, we'll explore the basics of polarit...
One of the main differences between a TIG welder and an MMA welder is the welding process itself. TIG welding uses a non-consumable tungsten electrode to create the weld, while MMA welding uses a consumable electrode that melts and becomes part of the weld. This means that TIG welding produc...
High Frequency welding (HF welding) or Radio Frequency welding (RF welding) is a method of joining thermoplastic materials using radio waves and pressure to create high-quality welds.
Manual Metal Arc Welding: This is how it works In stick welding, contact between the rod electrode and workpiece ignites the arc. This creates a short circuit for a fraction of a second between the two poles, meaning that current can then flow. The arc burns between the workpiece and the...
electricity between the welding electrode and the weld piece. The arc is generated when a sufficiently great voltage pulse is generated between the pieces. In TIG welding this can be accomplished by trigger ignition or when the welded material is struck with the welding electrode (strike ignition)...
and can also be used for circumferential seam welding, but the power loss is greater than that of high-frequency resistance welding. The main parameters that affect the quality of high-frequency welding are frequency, power, workpiece shape angle, extrusion pressure, distance between electrode (or...

F number: The F number variable requirement has been addressed in the QW- 433. For example if a welder qualified with SMAW process with E 7018 for carbon steel material cannot weld with the E-308 Electrode in same SMAW process. The F number for E-7018 is 4 and for E-308 is 5 and...
