Submerged Arc Welding SAW Working Process Equipment

Seam Welding Diagram Working Advantages and Disadvantages Seam welding is a resistance welding process in which overlapping sheets are joined by local fusion progressively along a joint by two rotating the circular electrodes Usually spot welding as also other ERW machines are automatic and work on the following weld cycle 1 Squeeze the two metal pieces together with a light pressure 2 Pass heavy electric current for a very brief time to obtain coalescence temperature 3 Apply pressure and hold for sometime 4 Remove pressure The rectifier welding machine works on AC power source and is capable of delivering ac high frequency as well as dc welding current There are various types of rectifier welders available in market however all of these are same in functionality and working Bound seam A bound seam looks like a French seam on the right side of the fabric There are no visible stitches on the right side of the fabric and on the opposite side the fabric edges are neatly enclosed Flat felled seam A flat felled seam is an extremely strong closed seam that is often used for items like jeans Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal and the melted metals when cool result in a binding of the metals It is a type of welding that uses a welding power supply to create an electric arc between a metal stick " electrode " and the base material to melt The working principle of resistance welding is the generation of heat because of electric resistance The resistance welding such as seam spot protection works on the same principle Whenever the current flows through electric resistance then heat will be generated The same working principle can be used within the electric coil Arc welding can be automatic and it can also be manual depending on the tools and machines that will be used The ends of the metals are connected with the use of electricity The ends of the metal pieces will be melted before they will be fused and solidified with other materials Seam welding is a variation of resistance spot welding In this type of welding the welding electrodes are motor controlled wheels unlike that of the stationary rods Due to this a “rolling” resistance weld or non hermetic seam weld occurs This method is frequently used to join two sheets of metal together The electrodes are rotated at a pre determined constant speed in the continuous motion process of seam welding The current impulses are also timed to get an overlapping weld The work pieces can be moved alternatively at similar speed with the electrodes idling under the welding pressure What is intermittent motion seam welding

China Circumferential Seam Welding Machine MIG Welding

The first practical demonstration of resistance welding was performed at the Franklin Institute in Philadelphia in and was “perfected” in It was in that the first production resistance welding machine was manufactured a Thomson Gibb machine HOW A RESISTANCE WELD IS MADE The basics of resistance welding are quite simple H F induction process is used to make spot static jig and scam welds however butt fillet and tee joints are difficult to make The welds produced are tight and strong The process can be easily automated to weld films sheets and tubes Lap welds by seam welding machines can be carried out at speeds as high as 27 to 65 m/hr In this blog I have provided basic information on the unique qualities and benefits of using a nanosecond fiber laser for spot and seam welding metals This is a rapidly expanding technology and new possibilities are found each day Please contact us if you would you like to know more about this technology and how it might apply to your process Jul 02 Welding Machine A welding machine is used to create the heat and apply the filler metal The filler metal is supplied to form the joint either from the electrode itself or by filler material The temperature of the heat produced is of the order of ° to °c com/articles What is Seam Welding Seam Welding aka Resistance Seam Welding is a type of spot welding that uses motor driven wheels This welding process produces the parallel seam weld and the single seam weld at the same time With the help of the continuous spot welding you can form the gas tight as well as liquid tight joints This welding process is very difficult to carry out for the sheets of metals which have a thickness larger than 3 mm Resistance Welding Definition Resistance welding is one of the oldest of the electric welding process is used by industry today The weld is made by the combination of the heat pressure and time All resistance welding spot welding seam welding projection welding etc are worked on the same principle of heat generation due to electric Laser beam welding LBW is a welding technique used to join pieces of metal or thermoplastics through the use of a laser The beam provides a concentrated heat source allowing for narrow deep welds and high welding rates The process is frequently used in high volume applications using automation as in the automotive industry Generally the welding location can be defended with some kind of shielding gas slag otherwise vapor This welding process could be manual fully or semi automated Circuit Diagram In Arc welding process heat can be generated through an electric arc struck among an electrode as well as the workpiece
