ABSTRACT
Welding being the major asset and salvation for mechanical
engineering, the seminar is all about the automation of major welding
processes used in industries using robots, which was hitherto done
manually under hazardous and perilous working environs. The seminar
dwells with two major industrial welding processes namely continuous
arc welding process and spot welding process. It also connects with
essential features of the robots used in these welding processes and
also the adv ....etc

Underwater welding refers to a number of distinct welding processes that are performed underwater.

The two main categories of underwater welding techniques are wet underwater welding and dry underwater welding, or hyperbaric welding.

In wet underwater welding, a variation of shielded metal arc welding is commonly used, employing a waterproof electrode. Other processes that are used include flux-cored arc welding and friction welding. In each of these cases, the welding power supply is connected to the welding equipment through cables and ....etc

ABSTRACT

Vortex refrigeration is a highly sophisticated system that contains a vortex tube which due to centrifugal force expels the internal energy of the air while the air at the centre core is made cooler. In this type of system the effectiveness is too low but considering its small size this can’t be ruled off. This is used as personal cooling system in suits that are designed to withstand heat.

Welding Processes
EN358 – Ship Structures
A Brief History of Welding
Late 19th Century
Scientists/engineers apply advances in electricity to heat and/or join metals (Le Chatelier, Joule, etc.)
Early 20th Century
Prior to WWI welding was not trusted as a method to join two metals due to crack issues
1930’s and 40’s
Industrial welding gains acceptance and is used extensively in the war effort to build tanks, aircraft, ships, etc.
Modern Welding
the nuclear/space age helps bring welding from an art to a s ....etc
