bridges and highways would be impossible to build without welding‚ as would oil and natural-gas pipelines‚ offshore oil platforms‚ giant wind turbines and solar panels. Welders help install and maintain boilers‚ antipollution systems and other large structures‚ as well as piping for industrial‚ commercial and residential facilities. Welding is even used by artists to create sculptures and decorative items. There is almost no limit to what welding can do‚ especially since developments in the technology

welder is something I have wanted to do since I started learning it. I knew a little about welding when I first started welding. I knew it was a very hot job‚ especially during the summer. I also knew that this field of work requires a ton of practice before mastering it. This job can also be dangerous and requires many safety procedures before actually performing it. One other fact that I knew about welding is that it is very hard work and a challenge. It is a challenge because of the patience and

WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

There are more advantages of public transportation than disadvantages of it. It is because there are three reasons to support the statement. These reasons are that environmental effects of using public transportation‚ cost of public transportation‚ and accessibility of public transportation. Firstly‚ we can save our environment more by using the public transportation. We could take trains‚ buses‚ airplanes to travel most parts in the world. Therefore‚ we should use the public transportation than

Welding Outline 1. History of Welding a. Welding can be traced back to the Bronze Ages‚ where pressure welding was first developed. b. The Egyptians were also one of the first to use pressure welding. c. The blacksmith of the middle ages was the one to bring forge welding into the world. d. Early types of welding were used for holding items together for some project. As for the blacksmith in the Middle Ages it was more for horse shoes or fixing iron material

Optimization of different welding processes using statistical and numerical approaches – A reference guide Abstract Welding input parameters play a very significant role in determining the quality of a weld joint. The joint quality can be defined in terms of properties such as weld-bead geometry‚ mechanical properties‚ and distortion. Generally‚ all welding processes are used with the aim of obtaining a welded joint with the desired weld-bead parameters‚ excellent mechanical properties with minimum

These interruptions may occur in the base metal‚ weld material or "heat affected" zones. Discontinuities‚ which do not meet the requirements of the codes or specification used to invoke and control an inspection‚ are referred to as defects. General Welding
