Nearly fifty percent of objects in the U.S are affected by welding, welding is the main driving force behind manufacturing. The history of welding dates back to 4000 B.C, although there is only proof of it dating back to 3700 B.C. Products were invented such as jewelry, utensils, and weapons like swords and spears. Although we use a different method than used in the bronze age, they both use the same method which is the melting of two metals to bond them together. Metals such as Iron, Bronze, Gold and silver were all used to weld. Thousands of years of welding gave us the life we have today.
Blacksmiths in 3700 B.C. were the welders, blacksmiths crafted tools out of many different types of metals and sold them to the people in their towns. They were some of the most important people in this era because without them it would have been almost impossible for people to do the things that they had to do. Blacksmiths also created many different objects such as horseshoes, body armor and weapons. Welding in this time consist of heating two different pieces of metal together at a very high temperature in a fire, which causes them to bond. This type of welding takes a lot more time and effort but in reality is the same way we do it today only without electricity. Blacksmiths in a way not only crafted different…
What is welding, and how does it work? Not many of us grasp what welding is or however it works. According to Blessed Virgin Book, “welding is the method of heating and melting metal components to affix them together” (www.weldinggeru.com). A welding machine uses electricity to soften the conductor, fusing one piece of metal to another. The attachment machine uses a ground that connects to the surface that allows the artisan to form a flowing current passing through the conductor and the metal…
2. RESEARCH ON THE STRUCTURE OF METALS AND TYPES OF BONDING.
What are metals?
24% of our planet’s mass is metal. They are used as mainly because of their properties; metals are strong, ductile, have high melting points and are excellent conductors of electricity. Other properties of metals are given below:
• Can be made stronger by alloys and heat treatment.
• Easily machined.
• Most of them are heavy.
• Susceptible to corrosion.
Metals can be divided into two; Ferrous and Non-ferrous.

• The weld is taken from a website: 
• Product: The weld is for a pressure vessel assembly joining the cylindrical shell and the dome shell.
• The type of the weld: The welding process used is a submerged arc welding process with a butt joint where a groove is made of different shapes and sizes in order that the weld pool may sit in the groove to join the parent metal parts.
The below mentioned figure represents the submerged arc…
quality of the welding in the manufacturing process by utilizing simulation, we have to briefly describe the used simulation process called Design of Experiment (DOE) and understand the characteristic of such analytical process.
Basically, the process of accumulating the data based on the observations is time-consuming and costly and miscalculation in the return of investment on the improvisation can be harmful to the organization. Therefore, different types of analytical software were…
