In most of welding process, The P nuer, F nuer, A nuer PWHT, thickness (out of specified range) are essential variable. Based on requirements of ASME Code Section IX all essential variable, nonessential variable and supplementary essential variable (such as Group Nuer ) must be indied in the welding procedure specifiion.
MIG welding requires a wire feed system. The wire feed system is what feeds the electrode, or filler wire, to the weld joint. This is where the term “Wire Wheel Welding” comes from. The wire feeds come in many different forms. Some are part of the power supply

Welding is a fabriion process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
What is induction welding? With induction welding, the heat is electromagnetically induced in the workpiece. The speed and accuracy of induction welding makes it ideal for edge welding of tubes and pipes. In this process, pipes pass an induction coil at high speed.

Heat stress is not only a serious condition for workers, but it can greatly reduce productivity and increase operator errors. The heat of the welding arc and added warmth of protective clothing can make already hot conditions even more intense for welders. Miller
The lower ferrite nuer is better for corrosion resistance, while balancing higher ferrite content to avoid solidifiion cracking in the weld deposit. I would not worry about lower ferrite nuers for clad overlay welding, if no cracking is observed (Liquid Penetrant
Inductotherm Heating & Welding Ltd Appliions from Banyard, iRoss, Radyne & Thermatool Inductotherm Heating & Welding Equipment is designed and manufactured to a wide range of specified induction heating and tube seam induction welding systems, from its UK production facility in Basingstoke, Hampshire in the UK.
During mig welding, one of the most common causes of excessive spatter is using too much wire. If you’re getting spatter everywhere during a mig weld, try slowing down your wire feed speed. If that doesn’t work, the excessive spatter might be the result of arc blow, which occurs when magnetism in your base metal affects the quality of your arc.

4/8/2020· Welding, brazing, and soldering equipment is used to join two materials—often metals—together. The equipment itself may consist of a complete system or station, power source, gun or torch, or a monitor/controller. The American Welding Society (AWS) defines welding as, "a materials joining process which produces coalescence of materials by heating them to suitable temperatures …

The manual arc welding (MMAW) or SMAW (Stick metal arc welding) process uses consumable flux-coated electrodes to produce heat by arcing as well as to supply filler material to weld zone. Metal and carbon electrodes are mainly used in manual welding in steel, alloy-steel, structural steels, heat-resistant steel, surfacing (build-up metal), cast-iron, mild steel, and other metal alloys.
