How do you prepare the materials in readiness for the welding activity?

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.

What is a nonfusion welding?
it should be called solid state welding which does not melt the base... in fusion welding the base melts as you weld.
What is another word for welding?
precocious leading
What is a non-adaptive robot?
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.
What is a flange rating?
*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:
How are robots used today?
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.
Why filler materials are used in welding process?
filler materials are used to fill the gap between the two job materials during the welding process
What exactly are Hobart welders?
Welder is a tradesman who specializes in welding materials together. Welding is a process that joins materials. Hobart Welders is a brand of welding machines. And yes, they are good.
What is a wps?
welding procedure specification its document for welding activity to be carried out in proper essential and non essential variables of welding
Can a threaded joint be welded?
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
What is a nonfusion welding?
it should be called solid state welding which does not melt the base... in fusion welding the base melts as you weld.
What are object of welding?
Welding is done to weld materials by operating a welding machine. Many industries such as Shipyard, Robotics will be needing welding applications. The applications include extending a rod eor pipe, joining two materials etc. My brother is doing a welding course at Weldtech Training Inc at Ontario. He is very much fond of welding. It gives someones great opportunities to work in several fields.
What has the author John Barry Moss written?
John Barry Moss has written: 'Science and metallurgy for students of welding' -- subject(s): Welding 'Properties of engineering materials' -- subject(s): Materials
What does mean for SFA in ASME?
SFA means Welding Filler Materials.
What does mean for sfa in asme secIX?
SFA means Welding Filler Materials.
Purpose of oxy-acetylene welding?
You have oxygen and acetylene to blend into the tip for a flame. It will be regulated by adjusting the regulators on the bottles and the welding handle will have adjusting ability for the temperature you need for the metal you are welding.
What is non fusion welding and types?
non fusion welding is when there is no filler metal needed...Actually all welding is considered fusion welding, meaning the material fuses together unlike soldering. The material has to melt to fuse.
Which gases are used in normal welding process?
Depends on what you think of as normal welding. Gas welding use oxygen-acetylene. MIG/TIG use Argon. MAG, use an argon-something mix. Depending on what materials you are welding, there are some more options tha might be used.
