it should be called solid state welding which does not melt the base... in fusion welding the base melts as you weld.
Non fusion welding is the collection of welding processes that do not involve melting the materials that are to be joined.

you must make sure the edges are free from excessive surface contamination e.g Rust, ensure edges to be welded are correctly prepared e.g, made flat.
A non-adaptive robot is that will follow the instructions it is given despite changes in the environment. It will only stoop until it is shut it down by a human operator. Non-adaptive robots are also known as open-loop systems, as they don't receive feedback from the environment and is hence incapable of making decisions and altering the output Non-adaptive robots are commonly used in the industry for many tasks, including welding a spot, putting steel into a furnace and drilling a hole. They may be reprogrammable, which means that they may alter their tasks by accepting new instructions. This is, however, only possible when the robot is equipped to perform the new task.
Robots are used today in a variety of fields. They are often used to carry cameras into areas where humans would be in danger, they are used to carry out surgical procedures, and they are used to build cars and other machinery.
*Any flange having different MOC bears the rating with respect to international standards like ANSI B16.5.*It is a designed pressure that a flange can withstand.*For example a flange is having the following specification:25NBX150#,FORGED CARBON STEEL as per ANSI B16.5is having 150 psi flange rating.It can withstand 150 psig pressure safely.(Noting that in most cases the pressure-temperature charts of a given spec will allow for normal operating pressure to far exceed the class rating at ambient temperature. For example a 150# flange in A105 Carbon Steel will rate for 285PSI at -20 to 100 Degree F. For more information see www.texasflange.com The original intent was to class the parts to safely hold the given pressure at relatively high temperature. Since often times the operating temperatures are much lower the flanges can usually be used well above their given rate. When in doubt take your design criteria to a company that deals in it and ask for the specifics.)*Pipe flanges that are made to standards called out by ASME/ANSI B16.5 or ASME/ANSI B16.47 are typically made from forged materials and have machined surfaces. They are typically in "Pressure Classes" such as 150#, 300#, 600#, 900# 1500#; however, ASME B16.47 still recognizes the 75# or "Class 75" flange for certain low pressure and low temperature applications. These "Pressure Classes" have both pressure and temperature ratings for specific materials. The flange faces are made to standardized dimensions and are typically "flat face" "raised face" "tongue and grove" or "ring joint" styles, although other obscure styles may be permitted. Flange designs are available as "welding neck" "slip-on" "lap joint" "socket weld" "threaded" and also "blind flange". The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details ( see ASME Code Section VIII Division 1 - Appendix 2 ). These flanges are recognized by ASME Pipe Codes such as ASME B31.1 Power Piping, and ASME B31.3 Process Piping. Materials for flanges are usually under ASME designation: SA-105 , SA-266 or SA-182.*Please visit following link and download the software, you will get both pressure v/s temperature rating of flange:
roster welding
One type of welding is tube welding. Another type if mig welding.
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
smaw welding is sheilded metal arc welding
what is the difference between ultrasonic welding & radiographic welding
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
Digital Control of welding when welding
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
Transformer type welding machine
tig welding
Auto darkening welding helmet is the best welding helmet.
